Samsung USB to SATA PCB Compatability

Don't Lose Your Data Forever!

DIY data recovery has risks. You could lose your data forever! Don't want to risk it? Talk to a professional now.

Strange case . This drive came in my hand 1 month before. Waiting for donor. Yesterday I've got some strange results.

Patient HM502JX/VPK BF41 00282A 00 usb Korea
Donor Hm500JI BF41 00294B 02 Sata China

PCB not compatible. I swapped this drives hsa to patient.

I have some PCB that I need to convert Sata.
Tried 4 or 5 PCB. 1 PCB worked
Donor PCB HM250JI. Lol 250gb

After than I've got ID. Capacity true. Backed up all modules , Rom . Tracks from 0 to 66. Not read any others. Error.

Cannot see folder structure. Cannot read beginning parts (blocks) Decided to clone disk. Cloned 40% parts ( in different locations not fully continiuously) Kinda big bloks) very fast and no bad sector. Fully good condition.. Remained parts (blocks) making long busy..
Everytime I made manual power reset and solve busy problem again and again and again. Till 40% I tried all reading settings. Same result.

I recently recognised that MRT recognised patient has 2 heads. I have swapped 4 head HSA from HM500JI. I remember it has 4 head. Checked again donor heads in MRT (patient hsa working only h3 died) says same 4 head .

I guess some ROM compatibility problem.
What is suggestions. Thanks.
BF41 00338A
Any guess compatible SATA

Can we see pictures of the Main IC and the Motor controller chips?

If I had to guess, I'd say that the SATA equivalent is a HM100UI drive which would mean that a BF41-00322A board would work. But, that's just an educated guess.

I'm a total noob in any data recovery matter. But I really want to give new live to a usb hard drive that I have laying around.

It's a BF41-00357A ---> BF41-00315A situation.

The fact is I don't want to recovery anything, I just want to use the drive. The question is: Do I still need to transfer the ROM chip? If the answer is no I'll buy a PCB right now. But if I had to, so it's over, I never used a solder before :lol: :lol:

Thanks in advance!

With Samsung (and only Samsung) you might be able to get away without transferring the ROM IF you can find a SATA drive with the same exact firmware version as your USB one. Doesn't always work, as there could be minor revisions in the FW code, but it often does work.

Greetings, I work for the company B&S data recovery located in Peru-Lima.
I have come across a Samsung USB whose PCB number is "BF41-00309A" which is not registered.
Making comparisons and with trial and error I have managed to find the compatible SATA PCB "BF41-00322A"
I share it so that it remains here as a reliable record for all.
I send you photos and a snapshot of the work.
