Dear friends,

I have a big problem and I suppose that you can help me. I have a portable Samsung 500GB HDD and probably PCB's defectived. I have to access my HDD to recover my data and because of that I bought a new HDD to change PCB and access to my old HDD. But it's didn't work . Please give a some advice to me about how can access my old data drive and get my datas!

HDD model : HM502JX
HDD P/N : HM502JX/VPZ
Capacity : 500GB

PCB : BF41-00288A 01



Many Thanks.

PCB ROM Transfer.

There are companies available which can do it for you.

Proper diags & info is needed not just "I have a portable Samsung 500GB HDD and probably PCB's defectived"

ie:

whats the fault?
was it dropped?
does the drive spin with the original pbc?
does it make a clicking sound?
is the usb port solder points ok?
Is the drive recognised in BIOS & disk management?

Give as much info as possible

Loki

Dear Loki, Sorry, You are right.

Fault : USB port broken, I repaired and tested, not worked! Get a new HDD, take off PCB and tried, didn't worked!
Spin : Yes, drive spin with original PCB
Sound : There is no sound, just flip-flop light of old and also new PCB!
Port Solder : I repaired old one, also I have new one.
BIOS : Not recognised by Bios, not on Windows, I didn't tried with third party Disk management programs!

Thanks for support again.

The square chip that has the big M (marvel) on it has embedded rom info that is unique to the drive.
This would require specialist harware to copy over to the donor pbc - not DIY

A quick search on this forum showed you might be able to remove two pairs of capacitors & connect the Rx & Tx to a SATA connection on the original pbc.

If you decide to opt to try a DIY fix then you accept the responseablity if it goes wrong.

Did you try your original PCB on your new drive?

Just curious ...
