Recently my external Lacie hard drive failed to power up. It had a slight burnt smell to it.

I cracked it open and inside was a Seagate Barracuda 7200.10 320gb.

So I ordered a new Barracuda ( identical ST3320820A ) with the intention of swapping out the PCB which I did. The hard drive is now spinning but I can't get the bios to recognize it.

The only difference between the two boards is the firmware. The old one is 3.AAC and the new one is 3.AAE. Could this be my problem and if so, can I fix it?

If you had a compleat new HD why did you not just use the whole thing?

The way you are doing it will never work with your old data (new controller firmware). You now most like need to format the HD.

Befor you changed the controller you should have checked to see if it would still spin. If it did still spin you should have run SpinRite 6.0 on it.

Whats wonderful about harddrives is that you need the same pcb, firmware and all, for a swap like you did to work.

To begin with it was a bad idea, but since the EEPROM for the HDDs are sometimes socket based and not directly soldered you may be able to swap the EEPROM.

edit: no such luck on your HDD

I do hope the OP had backups of his files. He defenetely voided warentys for both HDDs.

damn dude iam in the same exact place as you besides the fact that my harddrive is an old ide 60gb! consider yourself lucky. Iam gonna try and use magnifying glass and see if i can find the bad traces....yea...i hope.

First off, the use of SpinRite would have been a huge waste of time. Before doing anything, I strongly suggest you consider the value of the data to you. Any attempts you make now can and will most likely increase the cost of professional data recovery services. It is my recommendation that, if your data is worth $300 or more, you get take advantage of the free evaluation that most data recovery labs offer.

If you want to do the recovery yourself, you may get lucky with getting a PCB that is an exact match. But, the damage could be more severe than just the PCB and could also be with the head assembly and/or the SA tracks. If so, you'll need tools that will far exceed your budget.

Have fun!
