Why the HDD wont start the mac os installed?
I own a macbook pro late 2009 with 250 gb seagate 5400 rpm.
I replaced it with a HDD hitachi 500 7200 rpm.
It never finished the mac os installation but when i connected it externally through a usb it did well and the install finishes succesfully.
And when i tried to use the old HDD everything seems to be ok !
Would like if any one would help as am depending on this laptop for many tasks.
MacBookPro Mac OS X (10.6.4)
