I have a Toshiba MK3263GSX 320GB/5400RPM 2.5" SATA drive from a customer's laptop. The laptop's motherboard and hard drive were shorted out when the AC adapter was plugged in (I'm still trying to find the reason).

I've taken a look at the PCB to see if I could figure out what's wrong. I bypassed the "S" fuse and got the drive spinning again, but it still isn't accessible. Are there any other components I could troubleshoot?

I have a working 500GB Toshiba MK5055GSX with a nearly-identical PCB. Would I be able to take the ICs from the shorted PCB and have them work with the donor PCB? I have the necessary equipment for rework/reballing.

Here are photos of the drives:




If anyone can give me some tips on this, I'd really appreciate it!

I can see there is ROM on location IC602 if u can replace this onto the Donor PCB. This should start your dirive, if its a PCB fault

I just finished swapping IC602, and it worked! I've got the drive backing up via Acronis as I type this. Thanks a lot for the help!

I'm still going to try to get the other PCB working, but that's gravy at this point.

Thanks again!

Hi guys,
I've got similar case, MK3263GSX didn't want to spin, I removed the fuse, bridge the solder points and now works good - I'm making a data copy right now, but I want to use this drive in future so it's better to protect it with a fuse.

My question is related to spare fuse. May I use any working fuse from any Toshiba drive? if not, what shall I pay attention while choosing the fuse? Currently I've got an old PCB from 52GSX and I'm not sure if shall I use it?

Waiting for an advice, thank You in advance.
