There are many benefits to adding a second hard drive to your laptop such as improved speeds, greater storage space, and less heartache when installing new software. Use this guide to install one using our optical bay hard drive enclosure.

  1. Remove the following ten screws:
    • Remove the following ten screws:

      • Three 14.4 mm Phillips #00 screws

      • Three 3.5 mm Phillips #00 screws

      • Four 3.5 mm shouldered Phillips #00 screws

      • When replacing the small screws, align them perpendicular to the slight curvature of the case (they don't go straight down).

    How much weight can I save by removing the optical drive?

    gunes314 - Ответить

    You can save a lot of weight if lets say your installing a solid state drive or putting in a second hard drive but if you know that you use the CD/DVD disc drive a lot then you might just want to leave the drive alone.

    Marshall WahlstromHelgren -

    Also wondering how much weight I'd save by just removing. My drive is broken for ages, but I have not needed it in ages. The HD was already replaced by a cheap SSD (second best thing after upgrading to 8GB), so I'd appreciate losing some weight. I mean, the computer. Although I could lose some too... erm... well, anyway, I guess the lack of the DVD would not interfere with anything, right? Opinions?

    Carlos Duarte do Nascimento - Ответить

    Apple has meticulously balanced the MacBook's weight from left to right, and removing the optical drive may off-balance the Mac.

    Seji the veggie -

    What so you think that a removing the optical drive which weighs less than a AA battery will unbalance a MBP making it unusable? LOL!

    Unless you use the MBP on a high wire (an even then I have my doubts) you'd never notice the weight difference.

    pmhparis -

    The issue is not one of weight but an issue with the systems cooling and an opening which objects could enter. For a few grams of weight I don’t think its worth it! A better solution would be to swap out the heaver HD for a much lighter SSD, and getting all of the performance benefits of the faster drive as well!

    While you might not think it the optical drive also acts as a stiffener so there is less twist in the case. This is because of the size of the hole for the DVD/CD’s so taking it out weakens the case design.

    Dan -

    I'm thinking you'd probably be OK losing the DVD drive without a problem. Just make sure the optical drive cable is secured or you might hear it rattling in there from time-to-time.

    Wilder Torres - Ответить

    Since you’ll be removing many screws it’s best to plan ahead. I found it especially helpful to have a small plastic tray with about a dozen separate compartments to hold screws. As I removed screws I kept them in one compartment for each item removed. For example: The lower case removal involves the removal of ten screws. I kept them all in the first tray compartment and set the lid aside. Also, I put a post-it note identifying this compartment as “Lower case” and noted that the top right-most screws were the long ones. I continued with this methodology as a removed the next item, and the next, etc. Disassembly notes included for each compartment. This helped SIGNIFICANTLY as I was able to reassemble the Macbook easily by simply going from one compartment to the next (in reverse order). This guide is rated “Difficult” which it really isn’t when you plan ahead in this way. It saves time in the long run.

    when putting the macbook pro back together, the middle screw on the right side (if the computer is upside down and you have the hinge furthest away from you) requires a bracket that was not included with my new upper case. i had to remove it from my old case and transfer it over - if you don’t do this, that screw will have nothing to attach to.

    • Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board.

    • It is useful to pry upward on both short sides of the connector to "walk" it out of its socket. Be careful with the corners of the connectors, they can be easily broken off.

    Diego Hernandes -

    Did you properly ground yourself to the case before putting the spudger to the connector/logic board? Did you use a spudger or something else that is non conductive...or did you use a flat blade metal screw driver instead and compound your error by not grounding yourself before touching the logic board? All kinds of variables here but the bottom line is iFixit provided you a guide to fix your computer. Lots of others have followed this guide without trouble. Your battery issues are not their fault. They did say this guide was moderate difficulty...maybe it's just a little beyond your skill level. We should all know our limits!

    stiknrudder -

    Rather than be careful of the corners of the connector i would say don't use the spudger anywhere near the corners. While the corner looks like the obvious place to begin to pry it up from, it will break. Levering from the sides as the instructions suggest works well.

So be safe and don't fry your logic board in the process...

    Prying the battery connector off does not take much force. I did exactly what the guide suggested (walked it off back and forth) with the spudger without any problems. Just be very gentle, much like with anything inside laptops, they are very fragile and need to be worked with carefully. A+ instructions, battery replacement was a success.

    Its a lot easier and safer (corner wise) to pry it using the flat side of the black spudger directly in front of the connector (don't go/use the corners) very easily you will be able to pry it further by inserting the spudger into a better and thicker plastic section of the connector

    DON'T remove the Battery Cable, you risk the battery NOT being recognised when you start the Mac up again, or breaking it!! More to the point, APPLE DOES NOT RECOMMEND THIS, so don't do it! I Installed 2x 8GB ( 16Gb total) of Crucial Mac RAM at 1333Mhz for my Late 2011 MacBook Pro, and it works beautifully, fully recognised and working well. I followed these instructions, but as Apple didnt recommend disconnecting the battery, I skipped this step, and as well as taking less time, nothing was damaged or broken, and everything works perfectly!!! Just make sure that you DISCHARGE ALL STATIC ELECTRICITY FROM YOUR HANDS, by touching a metal surface in the Mac. Apple recommends the edge of the Optical Disk Drive ( Big silver thing ) before touching any parts. Also, Take care removing the RAM out of its packet, DO NOT touch the Gold connectors, and hold the RAM by the edges. Finally, be PATIENT, GENTLE and it should all go perfectly. I managed it first time, with no technical ability, so follow my advice. Good luck!

I turned it around with it guts open and guts hanging out. Screen was on. I forced it to shut down by keeping the power button down. Turned it back and first thing removed the battery cord.

    Luckily the computer started up just like normal. But hearing that sound was just too scary.

    BTW I had been cautious to de static myself multiple times.

    The guide worked perfectly, as it has in the past (our family has three Mid-2012 Macbook Pros that have been separately upgraded with RAM and SSD).

    The PH00 screwdriver fit perfectly.

    One note on getting the screws to seat easily and thread perfectly...always turn them gently a couple turns to the left (CCW or Anti-Clockwise) until you hear a small click. That's where the threads will grab. Works with any screw, but when threads are fine, this will help ensure that the screw is at the correct angle and will grab and seat perfectly.

    Great guides. Thanks!

    One other note: The screw heads fit flush with the curvature of the case -- which means that they aren't exactly horizontal. In other words, they aren't perpendicular to the table that the computer is resting on. Don't try to force them straight in vertically, because you'll risk cross-threading them.

    • Use the flat end of a spudger to pry the AirPort/Bluetooth ribbon cable connector up from its socket on the logic board.

    N.B! Thank you very much all you here on iFixit! Some IMPORTANT notes. Be very careful BEFORE prying the connectors up and down. They are very fragile and the picture could actually be seen as showing a bending loading in their weakest direction, AROUND its slender axis. The connector is slender and inserted on the logic board, so the gentle "walking" up and down should be done ALONG their slender direction and WITHOUT touching the adjacent connectors. If bending is done around its axis the soldering comes apart and the cable is done and gone. Just happened. These flat cables are one of the weakest design spots in my experience. They are a major time, money and geist consuming reason for malfunction like Wi-Fi connection problems, HDD, SSD not found internally but externally from USB issues et al being found on different forums. Thanks again and again.

    • Carefully pull the camera cable out of its socket on the logic board.

    • Though not recommended by iFixit staff, some users opt to omit this step completely. For information on this, see the step comments.

    • Pull the cable parallel to the face of the logic board. Pulling it upward may damage the logic board or the cable itself.

    "Carefully pull the camera cable out of its socket on the logic board."

    I followed these instructions to the letter, heeding the warning to pull vertically.

    The camera cable broke at the connector.

    The connector was pretty tight in the socket. Had to use a tiny screw-driver to free it. There was no way simply pulling would have worked.

    A quick google of "macbook pro camera cable broken" shows that this has happened to many other people, and been reported to ifixit. But no mention in the instructions. Disappointing.

    The MBP no longer boots. The cable is soldered to the LCD, which must be replaced. $500?

    I've replaced 4 dvd's with hdd's already, in different macbooks, so wasn't too fussed about #5. However; this time I broke the camera connector cable :(

    The connector is stil in it's socket, and I can't get it out no matter what I try. My guess is that some of the glue that connects the socket to the logic board, got into the socket as well. Prying with a small screwdriver, pulling with a pair of tweezers... nothing works. And this mbp belongs to a friend who uses his camera a lot for skyping...

    I hope we're still friends after I tell him.

    The thing is; I think it might be possible to do the whole operation with that cable still in its sockets; if you pull the rest of the cable free of the fingers, you can probably fold it out of the way when you lift the dvd out.

    You are so right about making sure to put back the two metal rings when you screw back the two (red) 10.3mm screws. I missed putting back one of the rings and read your comment after I had installed the drive and closed the macbook. Everything was working fine, but I went back to open it an leave it just as it was, with both metal (one with a plastic/cloth material around it) plates/rings attached properly. So it is very important to make sure you put those two 10.3 mm screws back with the plates/rings that they hold, exactly as they were before you put it apart.

    I think you should remark when re-assembling the machine, you should pay attention to the metal clip in Step 9, the upper left screw position, it's easy to miss when assembling, because there are so many wires, and it may be very easy forgetting putting the metal clip back in place.

    No idea how I'm supposed to put back the "grounding rings". Anybody?

    Sarge Izzard - Ответить

    As far as the grounding ring goes, it slips back over the screw hole, be patient and gentle. You may have to finagle the airport board under it first and then lay the board flat and reattach the subwoofer. I will see if I can add a pic in the near future. But that the best way to describe it.

    Another comment on step nine I have is about the subwoofer. In my case the screw hole that is for the "One 5 mm Phillips screw" (its currently circled in yellow) was broken [Mind you I have never dropped this computer so it came that way from apple. So be carful, it may be fragile and need some repair. Apple really needs to have better quality control on parts like this .(also they won't care that it was that way, they didn't like that I opened the computer, so even though its their fault, I should never have known and therefore they shouldn't be held responsible in their mind.) This may not void warranty as an over all upgrade, but any parts 'broken' or in my case 'found broken' during the fix are not covered any longer. So just be aware of this possible defect. Happy fixing.

    No need to unscrew the 2 orange-marked 3,1mm screws - they just keep the two black plastic pieces together. In the contrary, unscrewing these makes the job more wobbly.

    i managed to strip two of the 3 #00 Phillips screws on this step, so im going to try and explain how i removed them.

    i got a ratchet that is about 5" long, and a 1/4" socket that fit the bits in the 54 bit driver kit

    there are all of the parts that you need in that kit to connect it to the ratchet

    with this tool of torque i dropped down a size and use the #000 Phillips bit

    i pressed good and hard, and watched the head. if it didnt turn i pressed harder

    one screw was the worst and the #000 didnt work on it, just stripped it further

    so i threw the j000 on the end and gave it a go

    the shaper point on the j000 seemed to do the job

    i was on the verge of JB Welding bits to them and trying that

    After completing this step during reassembly, it may help to loosen the screw just right of the rightmost red 10.3 mm screw. Then, make sure the metal plate attached to that screw fits inside the small cut-away in the outer body. I tends to run just over it, causing problems later when screwing the lower case back onto the computer.

    • Pull the AirPort/Bluetooth assembly and the Subwoofer upward near the center of the side of the optical drive until they clear each other.

    • Move the AirPort/Bluetooth assembly and the subwoofer away from the top of the optical drive.

    The left part in the picture (the AirPort/Bluetooth assembly) is held down under a plastic tab that sticks out a tiny amount. Thus, it needs to be pulled very slightly towards the camera module in order to be able to lift out.

    • Pull the right speaker/subwoofer cable out from under the retaining finger near the side of the optical drive.

    N.B! Thank you very much all you here on iFixit! Some IMPORTANT notes. Be very careful BEFORE prying the connectors up and down. They are very fragile and the picture could actually be seen as showing a bending loading in their weakest direction, AROUND its slender axis. The connector is slender and inserted on the logic board, so the gentle "walking" up and down should be done ALONG their slender direction and WITHOUT touching the adjacent connectors. If bending is done around its axis the soldering comes apart and the cable is done and gone. Just happened. These flat cables are one of the weakest design spots in my experience. They are a major time, money and geist consuming reason for malfunction like Wi-Fi connection problems, HDD, SSD not found internally but externally from USB issues et al being found on different forums.

    I had the same issue. I got to Step 14 with no problems and then stripped the bottom left screw head! I was able to get it out with the help of a rubber band. You lay a section of the rubber band across the stripped screw, place your screwdriver on the screw pinching the rubber band. Then place a decent amount of force to engage the screw as you turn. Worked like a charm for me! Also, if you bought the ifixit optical bay hard drive enclosure they included two of those screws in the bag of screws (at least they did in mine).

    andrewsimpsonx -

    I had to drill mine. I cannot for the life of me understand how those got to be so tight or so easily stripped. The is no reason for either. Both mine stripped like a hot knife through butter.

    I had to drill mine out. Not that hard with even the crappiest of drill bits. One I had to drill completely out, although honestly I just got the head off and left it. The drive bay replacement I got only had a place for two screws anyways. The other came out as expected, one I got enough into the head I was able to reverse directions and it came out.

    I also did this without removing the camera cable and other items, just moved things out of the way. I took one tiny pull on the camera cable and knew better than to bother. You should be able to easily manage the items out of the way without causing any damage. Also, if you can only get one screw in, just make it one of the left screws. The unibody setup and placement of other items make it so that no matter what the drive is secure no matter what.

    As complained, the left bottom one was also annoying me, stripped out. If it is moderately stripped, then the rubber band would be the best answer as guided by andrewsimpsonx. The screw is tiny and shallow, so all you need is just one very hard pressing the screw, pinching the rubber band.

    Can’t secure the hard drive holder to those two left screw placements. I was able to get them out without any problem - but the dual hard drive holder piece doesn’t have the right dimensions for me to re-secure the part to the upper part of the case. Basically, the head of the screw is “too wide”, and cannot be forced past the side of the drive enclosure. Will be sending pictures to iFixit, as this needs to be fixed. Right now, I’ve got an empty hard drive enclosure (since the SSDs are out of stock, and I had a stuck CD in the optical drive that was really causing a lot of slow-downs and grinding noises) just sort of sitting in there. Figured it was a bad idea to leave a huge gaping space.

    I would then click on the Lion usb, and tell it to put the OS and time machine back up on the ssd.

    So I help down ALT and when it started it gave me the options of the usual Mac internal or the Lion USB.

    I clicked Lion, but instead of taking me to the install options (Disk utility, restore from time machine etc etc) it gave me that grey circle with a diagonal line through it. The no entry sign - grey on grey - that I think you have.

    Some googling said that it is because I was trying to usb a 10.7 install on a MBP that shipped 10.8

    You can't go back, apparently.

    So if any of the OSs are older than the mac you got, you will get this error. The grey in grey no entry.

But when i put the HDD in the unibody laptop dual drive (iFixit), it is not recognized via the USB-port(however, the HDD starts spinning) or when installed in the optical bay.

Long story short - all of my issues are resolved thanks to some disassembly/repair work and new parts from iFixit!

    Same problem happens, i don’t know how to fix that as well. Anyone has any idea? Thanks

    I followed the tutorial and everything works fine when I use an HDD 320 go but when I use the new HDD I bought which is an Hitachi 1T 7200T 2.5 P I have some trouble. The disk utily takes a long time to recognize the new hard drive and then starts not responding.

    I tought my new HDD might be broken but when I use it with an external portable HDD Enclosure it works fine...

    Any ideas?

    I do believe the max size HDD is a 750GB. 1TB might be too big. Though the ONLY place I found this stated was on iFixit. No where else.

    I just have finished installing second SSD to my MBP (unibody 15` 2010).

    First one was changed like one year ago. Samsung 500GB SSD. It is in my HDD bay and I'm running system from it.

    Today I put a new Samsung 1TB 850 Evo 1 SSD in to my optic bay.

    I encounter problem with SSD not recognized by Finder.

    But It was recognized by Disk Utility.

    What I did was I erase new SSD by Disk Utility. Then the new partition was created and now It has been seen by Finder.

    So If you see it in Disk Utility just erased it.

    Some extra info in under this link--> https://discussions.apple.com/docs/DOC-4...

    Wish you all luck :)

    Hi all,

    I did this and all seemed to be working fine, both drives showed up and all was good then about 20 minutes later i got a message saying that "the drive had been ejected incorrectly" or something like that. The drives have now disappeared from finder and Disk Utility. I took the SSD out of the superdrive caddy and put it in an external USB3 caddy, it's working fine. I even left this connected over night (all OK). This morning i put the SSD back into my Late 2011 MacBook and the same thing happened, 20ish minutes and then the eject message... Have i missed something?

    Any help would be very much appreciated.

    Dear iFixit

    I changed my Hdd with an ssd using this guide. My hdd is now in a caddy where the optical drive used to be.

    I can see my original drive ( Toshiba 500GB ) in the disk utility-app, but i can't reach my data on it.

    When i take it out of the caddy again and put it in a external Hdd case, i can read it perfectly fine.

    So there is nothing wrong with the hdd or the connection.

    Is this a problem i can fix with software?

    Thx for the help!

    Those were Phillips #00 in my case, not #0, on the small metal mounting bracket.

    • Don't ditch that drive! You can still use your optical drive externally with the help of our SATA Optical Drive USB Cable.

    • Align the cable's SATA connector with the drive's port and plug in securely.

    • Plug the USB connector into your laptop and your optical drive is ready for use.

    There is a small metal button in the front of the drive and you can use that to eject the drive if you were wondering.

    Joseph Landry - Ответить

    my drive’s connector is nothing like that, and I’m wondering is it possible to connect it to another computer?

Has anyone else noticed their Macbook booting and responding slightly slower with this duel-hard drive setup? I first swapped out my main hard drive for a SSD and the computer felt amazingly quick. I then replaced the optical drive with another SSD for additional storage and backup and ever since then the computer has felt slightly more sluggish in general. I suppose the CPU now has to constantly communicate to the second SSD where it could mostly ignore the optical drive before. Has anyone else noticed this?

Landon McKee - Ответить

Just fixed that issue:

Put the new SSD where the old HD used to be. Put the old HD where the optical drive used to be.

I found that the ports in the motherboard inside the mac have different speeds. The HD port is 6mb/s and the optical drive is 3mb/s.

chicle -

Are you sure its MB/S that would be horribly slow.

Zarkex -

I am seriously considering replacing my old HDD with a SSD instead of using a dual drive. Would you recommend still adding a dual drive with new SSD/ old HDD or just replacing the HDD with an SSD. I like having an optic drive, although not necessary. I am looking from the point of utility and practicality. Cheers!

Looking to upgrade my 2007 Macbook Pro (yes its still kicking... barely).

Im looking to purchase a new 2015 13" MBP non-Retina and was wondering if the dual hard drive upgrade is possible since all the installation instruction out there refer to a 2012 MPB unibody. Has nothing changed for the 13" non-Retina since 2012 or am I going to run into difficulty/surprises with the 2015.

Thanks in advance,

Huey Na - Ответить

The 2015 rMBP uses a m.2 SSD, and does not have a 2.5" HDD slot. The mid 2012 non retina MBP is the last generation that this mod works on.

Do we need to reinstall OSX after replaced it?

Sen Phina - Ответить

Successfully did this.

Didn't unplug camera, battery or speaker. Didn't remove orange screws from airport/bluetooth and didn't unplug antenna. I was just careful with the cables. One of the screws at the top left of the optical drive was sticky but just used a little contact cleaner and it came away fine. Everything is working as it should.

swirlykev - Ответить

Will this work with 2 SSDs? I replaced my HDD earlier with a 500GB SSD and if I wanted to add a second SSD in the old optical drive site, would that slow down the computer or require tinkering with the OS to get it to accommodate two SSDs? Or if I did this, should I get a new HDD and put it in the optical port site (I prefer the SSDs because I "throw" my computer around a bit, keeping it in my backpack as I'm a uni student and I know that jostling a spinning HDD can cause problems)?

irisremillard - Ответить

Kicking your mac around shouldn't have any noticeable effect on the hard drives - if you drop it from 1m every once in a while then yes, otherwise not really - remember iPods had hard drives for quite a while. Your computer sees hard drives and ssds the same way, you can have as many of either as you can fit

Darie H -

Great guide! Made it relatively easy to perform the upgrade. I did skip steps 6,8 and 11. Skipping steps means being more careful not to stress cables, connector or boards when maneuvering things around. Most connectors are pretty simple, just about weighing the odds of breaking a part by trying to remove/reconnect things or by working around the connections. Like every repair be diligent and take your time. It takes much less time to read and look closely at the steps then to order and reinstall another part.


nouzul - Ответить

TIP: If you do not have wifi and bluetooth after completing the the upgrade don't panic and stay calm. Assuming you were careful during the procedure you may have disconnected the airport/bluetooth board from the logic board. Without taking the airport board apart it looks like there is only one connection on the ribbon cable, on the logic board side. However there is another connector under the black material on the airport board side. Simply press your finger on the airport board right beside where yhe ribbon meets the airport board. If you hear a click you may have just solved your problem.

nouzul - Ответить

I skipped 6, 8 and 11. Works fine just means you have to be more careful moving things around as opposed to being more careful disconnection (and reconnecting cables).

nouzul - Ответить

Are there instructions for how to set up the SSD/HDD setup? I mean, what is the best way to migrate system OS to the SSD but keep data on HDD? Am I missing this somewhere? Thanks!

You may need to use disk util in order to create a partition on the new drive before being able to "see" it.

Everything in my macbook works just fine after going through the procedure above, but now my computer doesn't recognize my external dvd drive (I bought an LG cd/dvd drive). I've read in some places that because there is no optical drive internally now, the computer won't even recognize external drives, without having to make some changes. Any idea how I can solve this? Thanks!

jenkinssahline - Ответить

Bought the ifixit dual drive mount and tried to install my original HDD in the optical bay, but the mount is to big to fit property. The optical drive has cutouts on the left side for the CD/DVD entrance plastic, the mount doesn't have this and won't come close enough to the keyboard for the screws to fit. Ill probably take a tool and make cutouts myself but a huge minus for the part, 40€ + freight, freight was late and have to mod the part to use it. Not recommended! Just switch the HDD to an SSD and keep the optical drive.

Which model of Macbook Pro do you have? I found this to when installing it in a 2012 13" Macbook Pro

Worked perfectly. As noted below in Landon Mckee's post, at the top of this page, this installation should only be used for a secondary storage drive not your primary or OS drive as the ports they are connected to run at different speeds.

Steps 9 & 10 are the only slightly tricky things to get right. I wasn't too keen on pulling the parts so far apart, as they felt very delicate. Instead, I just pushed them very slightly away from the top housing screw of the optical drive so I could gently get my screwdriver in to remove the screw.

I didn't remove all of the thin wiring either, like most of the commenters here.

The upgrade went really well. It probably goes without saying that you need to take your time, have a LOT of multidirectional light and the right tools. Also be organised. Place the screws into a receptacle in the same order/position you take them out. A bit of double sided tape helps - gently place the removed screws onto it in the same 'shape/order' as you remove them. A magnetic screwdriver head is also essential. The key word here is GENTLY - and then this really is a doddle to do.

My firmware is up to date. I have done internet booting. I have booted from a bootable Siera AND El Cap flash drive. I have tried resetting PRAM. I have gone through power cycles. I have swapped out SSD locations to make sure they work fine, and they do. The issue is the drive that's in the Optical Bay won't read. When it does read, it doesn't let me erase or if it does, it fails when I try to RAID them together. I've been working on this for over 10 hours within last 3 days trying to figure it out. My old HDD works fine in the Optical Bay, but my new SSD doesn't. PLEASE HELP.

Colton Carr - Ответить

My guess is, the drive connector or ribbon. Also, some caddies have switches. For the most part, the caddy has to be out to see them.

My mid 2012 15 inch MacBook Pro does not work with a SATA III drive in my caddy, but works fine with an older SATA II drive. I'm thinking this is a hardware or software limitation.

Weird that it works with older Macbook's. The drive that failed worked fine in a non pro mid 2010 Macbook. Albeit in SATA II mode since the MacBook didn't have SATA III.

emkey1 - Ответить

One more piece of data. I bought a brand new SATA II 1TB drive and it worked fine in the caddy. It seems pretty clear the issue is with SATA III devices. It's a bit of a bummer since there aren't many SATA II drives larger than 1TB.

Thought I had a hard drive problem when computer wouldn't boot up. Took out HDD and connected with SATA cable to USB and the drive is fine. So I'm guessing the problem is the cable (which looks fine) or on the board. Was considering using this fix to put original HDD in optical drive slot but I see people remark that it will be slower than it was. Question is, how much slower? Too slow for a college student who doesn't use it for much other than internet browsing? Would I be better off getting a case for the original HDD, or just a new external drive, and continuing to use it via USB? Is that slower or faster than the optical drive connection? Thanks.

This guide is fantastic and very easy to follow!!

My Mid 2012 13" MBP's System Report shows a Link Speed of 6Gbs for my optical drive connection (should support SATA3.0). Using the first optical bay I purchased, my computer would not recognize a 2TB SATA3.0 HDD, a 120GB SSD nor would it recognize a 1TB SATA2.0 HDD. Strangely, the caddy worked with the stock SATA2.0 HDD.

I bought a different caddy from Amazon and all drives worked perfectly. Correct me if I'm wrong but most Mid 2012 13" MBPs should support SATA3.0 in the optical bay. If your SATA3.0 drive isn't recognized by your MBP, it could be due to a compatibility issue between the drive and the caddy you purchased. Try purchasing a different caddy before giving up.

I did everything as this manual explained. I put macOS on the SSD drive and computer started. No problem at all. Everything worked fine. I could install other applications, etc. But the next day, without me changing anything the computer doesn’t start anymore. The green light from powercable is on. But it seems that the computer doesn’t recognize the battery anymore (?!?). Sometimes if I try all kind of starting procedures (like option-command-R start or command-r start …) it starts for a few seconds and then shuts down.

Just replace HDD with SSD and leave the optical drive because you risk damaging your Mac. Use an external SSD or HDD for storage or a USB thumb drive / SD card.
