Hi Guys, I am new to this forum and in great need of your help. My GF's HDD's PCB main WDC IC chip overheated - trace of chared discoloration on insulation pad. Several presentations that she worked on are on that drive and no recent backup (but of course). She's devastated and can't really afford a full-blown data recovery service.

I was able to find a few close matches - both model and DCM; but in several cases the PCB code (both etched and on white label) don't match. How close do DCM and PCB code need to match to revive her HDD?
The HDD was in Dell Dimension 8110 PC - etched PCB code: 2060-701-265-001 REV A; white barcode label (by IDE pins): 2061-701265-200.
Thank you very much. Arthur.

There is a chance for cheap repair of this drive if You are quite lucky. You must find any WD drive that have logic board with printed number 2060-701265-001. It's also possible to use other compatible 2MB cache version of it with number 2060-701266-001. Any WD drive has it with MDL xxxxxxxx-xxGxC0. Then You must swap ROM chip (8-pins) located in U12 from fried PCB to good one. Be careful not to overheat them during resolder. If You don't how to do it, give it to pro that can do the job for You. Then drive should work again. If not and drive will be clicking, then You have bad luck as preamp of one or more heads are dead and from there the only way to recover it is DR company. Good luck and let me know if You are success.

But other possible complications should be considered also. If data is irreplacable then DIY should be last resort, not first.
