PCB swap on a Samsung HD501LJ -- howto?

[rchadwick]

Actually, from the way the part looks, a carefully placed squeeze from diagonal cutters would snap the part in half. If it's completely in half, it's no longer in the circuit, and you don't even need to remove it. When cut in half, you'll be able to bend both ends up and out. Doing this back and forth a few times should break off the diode pieces, leaving just the leads. Again, if you're just doing data recovery, you probably don't need to even replace the part. The drive should work fine without it.

If it doesn't work with the diode removed, I'd send it in somewhere.

Hi

I have the exact same problem as the poster with the same drive and the same faulty part (suppressor)

Could someone please tell me where I can order the part in the UK and what the part number is ?


Many thanks

Hi all,

I've had a similar problem - destroyed a HD501LJ PCB with a short-circuit, one of the circuits has burnt.

Tried to replace the PCB with a similar one from a newer device, but same firmware revision (A) and same PCB model (Rev06). The disk spins, starts, then stops, and isn't detected (maybe does that mean it fails to recalibrate, just guessing here). Am I totally out of luck or can I still do something without calling an ultra-expensive disk repair service ?

If I understood correctly, I might have to swap the ROM, but I couldn't tell which chip is it, and it might well exceed my soldering abilities.

I've also got a HD500LJ, which is basically the same with less cache, is it worth giving a try ?

Needless to say, I really want the data on this HDD back.

TIA

Hi,

U are facing some FW incompatibility. The bad news is that these drives have their ROM within the processor...
