Hard Disk spins normally. No weird sound.
The sata-2 connector is O.K. Blue light is on.

when I plug "USB device not recognized" message appears. I reflow and resolder "The coupling capacitor.


after that message disappears.

I need data. How can I convert to SATA?

More than resoldering those coupling capacitors ( don´t know, never saw problem in that area ) you should check the usb connector, those chokes pointed with white traces in your picture, and check continuity with an usb cable inserted fromt he pins in the computer-side of the cable to the processor side of those little chokes.

Also, depending on the disk/computer, you need to use a powered usb hub or cable with two usb connectors for these to work.

Replace the PCB with a new one from a drive with the same FW version ? If not possible get a SATA compatible drive + PCB and adapt the PCB to the drive ?

ISTM that the drive is OK but is unable to communicate with the bridge IC.

Yes, you are right.
Unfortunately, my PCB is BF41-00309A 00.

I have a Samsung HM321HI . its PCB is BF41-00315A-05. it looks like compatible.
swap roms but it's useless. motor can't spin.

maybe I had a mistake .

The HDA contacts are completely different. I hope you didn't damage the preamp.

donor drive is O.K. (hm321hi)
But the patient is not spinning anymore.

Motor Chips area was overheating. i immediately remove the power.
i took only 3-4 seconds. nothing fried. (i hope)

PCB looks like gone.. could i burn the rom chip ? (i hope i can't)

when i isolate the head contact motor is not turning anymore . is this good news?
is that mean Preamp's O.K.
