Hi I have a Toshiba MQ01UBD100 which stopped being recognised by Windows, so I tried moving the BIOS chip over to a MQ01ABD100 PCB (SATA version of the board) but it clicks when starting up, and eventually gives me a user password prompt. The original drive was not password protected. Are there any chips that need to be moved across to the SATA PCB?

Post pics of the two PCBS, clear enough so we can see the numbers on the chips.

I suspect the pcb's aren't compatible.

Correct!

If the PCB has a different motor controller it WILL click.

So it should just be a case of swapping the motor controller over then?

I believe that G003138A should be a match:

Hmm that comes from the 750GB drive, so I thought the 1TB board would work.

The original USB board has a TLS2605 controller, which is the same on the SATA board which I swapped the BIOS chip to - G003235C

remove duplicates from string

Furthermore its reported on Data Medics that a G3448A to G003235C swap should work.

I should probably also add that I bought a second G3448A board, swapped the BIOS on to that as well and the drive just did nothing. I verified that the BIOS chip was written correctly by taking the chip off the board and reading it back out with my TL866
