WD WD20NMVW spin up, but not recognized

[lordjohnny]

Hi.
I have a WD My Passport Ultra with a WD20NMVW 2TB inside.
The hard drive spin up, and after 1 minute spin down. The USB interface is recognized for Windows, but the volume and drive don't appears.
I try change the PCB with bios chips SWAPS, but same results.
Mac detects the usb as:

Code:

            My Passport 0820:

              Product ID: 0x0820
              Vendor ID: 0x1058  (Western Digital Technologies, Inc.)
              Version: 10.07
              Serial Number: 575835314142334838373034
              Speed: Up to 480 Mb/sec
              Manufacturer: Western Digital
              Location ID: 0xfd120000 / 4
              Current Available (mA): 500
              Current Required (mA): 500
              Extra Operating Current (mA): 0

Hi.
Thanks u for your response, i will should contact with a specialized data recovery service.

Another thing:
Windows recognized a WD Ses Device, and if i try update firmware, the tool detect the serial number, firmware version, ...
The WD Firmware updater detect a upgrade, but when try to update fail.

Regards and thanks u

Did you swap the chips yourself? Or you sent the PCB out?

As said earlier, the fact that it spins down most likely indicates the heads/preamp is bad.
