This OneTouch 4 Mini hard drive was bought at a Fry's store in 2007. It has a 80 GB capacity, and a 8 MB Buffer.
The drive has an estimated read/write speed of 28 MB/s
I am tearing this apart so I can put this under Spinrite to fix the drive from a unreadable sector.

This teardown is the same with the other onetouch 4 mini models.
-
-
-
The drive's enclosure doesn't have any screws or glue holding the case in place, it has a clamshell-style design that cradles the drive inside.
-
There is a seam at the bottom edge of the drive where the 2 halves comes apart. A flat head screwdriver helps pry it open.
-
-
-
The drive is suspended in the middle of the enclosure by several foam rubber pads, which keeps the drive quiet and keep vibrations at a minimum.
-
The metal plate covering the lower part of the drive is an EMF shield, and is where the SATA to USB board is held in.
-
-
-
-
Removing the shield is removing the 2 philips screws on the side of the drive where the shield is held in place.
-
Lets see what kind of chip and drive do we have here on the next step....

-
-
The other side of the drive. The sticker on the connector, is the serial number.
-
The controller board and the drive is connected using SATA.

The 2.5" hard drive in the Maxtor OneTouch 4 Mini isn't a Maxtor drive at all. It's a Seagate Momentus 5400.5 LD25.2 hard drive.
-
Here is the Seagate product overview to the Momentus 5400.2 hard drive, model number ST980210AS
-
Removing the EMF shield reveals a small PCB that plugs directly into the SATA and power connections of the Momentus 5400.5. It doesn't even have a physical connection to the RFI shield -- it just hangs off the back of the drive itself. The SATA connections to the drive are soldered to the PCB itself.
-
The controler board's chip is made by Initio. It is a Initio INIC-1605 USB to SATA Bridge Chip

-
Even though the hard drive's label reads "Not Suitable for Laptop Computer Use", it still works perfectly as a laptop hard drive.
