I'll try to be as specific as possible here, so am going to make a bunch of statements to give as much information as possible.
I am using a MBP running OSX. I am very precious about the data on the drive, have looked into a data recovery service and will undertake it if I establish that I really shouldn't try anything.
I am competent enough to undertake the fixes I suggest, but first - the facts.
- The drive makes no noise when you plug it into a usb port.
- The drive is not recognised in disk utility.
- The problem is not the cable, i have tested it, and tested alternative cables.
- The problem is not the usb sata controller, i have tried alternative drives on the controller, and have tried alternative controllers on the drive.
- The drive is a toshiba MQ01ABD100
- Spinning the drive in my hand does not make any audibly 'odd' noises, it sounds fairly normal, and sounds the platters are rotating freely.
- I have not opened the case, and want to keep it that way.
The above tests have led me to believe that the problem is the logic board on the drive.
I can't see any components that look problematic to the glance, and continuity testing (using a multimeter) says that all of the fuses on board are intact.
Voltage tests show extremely low voltage on the motor power points (a tenth of the power being sent by a 2.5" WD drive i have), which further implies logic board issues.
I want to buy another drive as close as possible to being the same model. I'm confident I can buy the same model, but am also not kidding myself - lets face it, the revision is going to be different.
I want to use the new drive as a donor drive, and swap the logic boards.
Anyone see any problems with my logic, or my plan?
I have all the time in the world, its not mission critical.
