Hi all,

First of all, I'm new on this forum. I've read a lot of topics and post for the repair for a Barracuda ST500DM002. It is an F3 line.

I would like to have some feedback on my plan of action.

Situation:
Drive doesn't spin. I have got several drives with the same pcb and that are a match with the Donor Drive Donor Matching Guide. I've put the bad pcb on a working drive, and it won't spin either, so there is something wrong with the pcb of the defective drive.

Question:
- soldering and transferring bios chip is the only option / is the way to go?
- backing up rom settings and loading on new pcb is that in a way possible?

Just to be sure before I head to a store where they have a hot air gun..

You could use a programmer with a SOIC clip to read the chip, but then you have the issue on how to write it to the new PCB.

But if you have a TRUSTED soldering guy then it would be easier, if he/she messes it up though it's pretty much game over!

Have you tried the donor PCB on the patient drive just to make sure it spins. If the original PCB had some sort of electrical failure/surge it may have affected the read-write heads inside the drive.

I have just tried it, it spins and makes clicking noises, not the normal sounds of a working drive (but that might be because rom isn't swapped?

Yes that can be caused by an incorrect ROM. At least the drive spins which is a good sign.
