WD BAD PCB Device USB My Passport Essential SE 750 GB

Hello,

I have the following problem with my external hard drive. It is a model ‘My Passport Essential SE 750 GB USB 2.0/3.0’.

P/N: [Deleted]
Model: WDBACX7500ABK-00

Always it has worked correctly, but from yesterday when I connect it to a PC or Laptop pops a message “WD BAD PCB USB Device” and “WD Ses USB Device”, then request install the driver, but it doen’t recognition the Driver. (II have instaled the last ‘WD SmartWare 1.6.2 and WD Ses Driver’)

When I go to Windows Storage Disk Management, the device doesn’t appear.

I have used the Victoria Software and the Device been showed and the follow information:

Model: WD BAD PCB; 
Capacity: 1 LBAs
Firmware: 0000
Disk Size: 1LBAs 0kb
CHS: 0/0/0
Features: Not ATA 
Sector: 512 Byte Revice it!

[Warning] Invalid drive geometry!

But I don’t know use this software.

Also, the UVCView Software showed:

Appreciate any help to assist me recover the possible amount of data I can.

Thank you in advance.

If the PCB is bad you might need to get a new one. Now to my understanding it needs to be the same, if is not the same you might damage the unit further.

Where Could I get a PCB for this hard disk model (WDBACX7500ABK), Do you know, if Is it selling by WD or Partner?

Is it as easy as replacing? Do not have to change any chip on the PCB?

Thank you.

Regards.

FWIW, here is a similar problem:

Here is a comparison between your device and a functional Passport (may not be the same model):

AIUI, your Passport probably integrates the USB-SATA bridge IC on the HDD’s own PCB. I believe Essentials models incorporate AES hardware encryption, so that could be an additional problem. Even in the absence of encryption, you would still need to transfer unique “adaptive” information from the patient PCB to the donor PCB.

It would help a lot of we could see the “bad PCB”, but this would entail opening the enclosure. You might like to ask WD’s Tech Support for permission to do this, otherwise you would be voiding your warranty.
