WD1600JB - needs PCB replace

[chaynik]

I try to use this disk with ATA-to-USB cable and power adapter. When turn on the power disk initially runs but then the adapter blow out and the disk too. The disk smells suspicious and when I remove PCB, there are some burned parts (U5, U7, Q1 and L1) as cen be seen on attached picture.
My HDD MDL is WD1600JB-00GVC0
DCM: HSBANT2CA
PCB label is 2061-701265-200AL.
I bought donor PCB (not HDD) with the same first part of the label, but the secont part differs after XC 1X68.
I have replaced PCBs and turn on the disk, but the heads just clicks and nothing hapened. May be I have to replace U12? Or pre-amp inside HDD is damaged too? If yes, what DCM donor HDD I have to look for?
Sorry for my English.

Move U12.

If it still clicks then you have bad preamp (which is quite likely by the extent of the burning)

Agree pcb is a heck of a mess .

Wow! Thanks to God, all data was restored and moved to a new disk! The drive revived after replacing U12. Now I can try to revive my other two died disks...

good to hear that the drive works.
so how did you match new PCB to your existing hard drive?
is it OK if PCB matches to the HDD model number (00GVC0 in your case) and DCM? (with replacing U12 of course)
