Any ideas here?

Motor Controller on PCB board went out.
Purchased replacement PCB board, swapped BIOS, Installed, didn’t work.
Obtained another PCB, swapped BIOS, installed, didn’t work.
Both boards before BIOS swap would run the hard drive, and show the drive on the PC but would not read the data.

My suspicion is that the shop that swapped the BIOS overheated it so the original BIOS is gone.

While I believe that obtaining a third PCB board would cause the hard drive to spin up and the drive to be recognized on the computer, I’m not so confident that it would cause the computer to read the contents of the hard drive.

Any suggestions?

First off you do not swap BIOS you swap ROM on the boards. If who ever you chose to swap the ROM chip destroyed it then you will need some help in this one. It will not help for you to try again on this one. Hope the person who swapped your ROM chip did not destory your ROM.

hi,
what happen when you swap first two PCB? does it spin up?
see my procedure as following:
i will swap ROM chip with first PCB. if nothing when power up. then swap return original ROM PCB and attach it with hard drive. even it no original ROM chip for this drive. mostly it can be make hard drive spin up. if it spin up with clicking. meaning this PCB is fine. these operation for make sure PCB is good. and original ROM chip may have problem. swap original ROM to this PCB again and check try to check and re-soldering it. as my experience some customer that re-solder should help. badly it still no help. take off PCB and check head stack connector which connect with with PCB. it may cause hard drive don't spin up. try more PCB will waste money.
had the find out the real problem with it.
what happen with third PCB now? does it recognized correctly? it recognized correctly should be access data area that you can backup your data.

When I swapped the PCB the hard drive would spin and would be recoginized as "G" drive. The hard drive works fine with the exception that the computer wouldn't read the data on the hard drive. When the ROM chip was swapped the drive would no longer spin or be recoginized.

So if I purchase another PCB and install then I'm sure the drive will spin again and once again be recoginized as G.
