Hello,

can you gie me some tips for part numbers or parameters of those L1 and L2 parts (assume that's coils) located on the PCB of the drive?
Both are physically broken. The drive was inside a plastic box with usb-sata electronics connected. No one could physically damage the board. So I guess it was low quality of that part.
Can I solder any coil matching that size? As I've seen on some published pics on the net, those two coils have an A and H respectively on the top of the body.

Thanks
brunoz

If you don't have a stock of drives to take from , I think it's better to find a replacement board on Ebay and swap Eprom.

Should the eprom IC be the same on donor board?
I saw 8-leg SMD IC and should not be a really big problem to replace it from the defecitve board. But someting did blew those two coils - maybe whole board is deffective.. Dunno. The drive spins up, revs, the heads are making short starting quiet noise (i thonk that's normal - no ticking) but isn't recognized.

Those two coils appear to be part of the Vcore and Vio converters. If either of these rails was defective, then the drive wouldn't spin up. Did you measure the output voltages at each coil?
