Hello all -

Found some great information on these boards, and I wanted to submit my specific situation for consideration. Seems like there are quite a few members (attn: fzabkar!) who are knowledgable about this specific subject. Here are the details:

My WD My Book Essential Caviar Green drive was connected to a USB hub with an incorrect, overpowered power supply. One hard drive and a mouse were fried, the other HD was miraculously spared. When I plugged the hub into my MacBook Pro Laptop, it caused the laptop to reset but it is seemingly ok, as are the two USB ports.

The My Book Essential Drive still lights and spins when plugged in, but cannot be read by any system. I cracked open the housing to discover the PCB board and the other circuit board in there showed visible signs of damage.

A few photos are at this link:,jt13LmK,JK8h2tN#0

My questions to you guys are the following:

If the drive still spins but the PCB is cooked, what are the chances that data is still there?

If I replace the PCB board, what are the chances I can access my data?

While the board appears damaged, the electronics on the drive itself seem fine. Is this a good, bad, or irrelevant sign?

This is my primary Time Machine backup, but also had a few other files on it. The problem is I can't exactly remember what is on there, and don't want to spend a fortune to recover it.

I was able to get the drive to be seen by Mac's disk Utility using a USB Sata connector.

It says the following:
Disk Description : WDC WD20 WD-WCAZA8794644 Media Total Capacity : 2 TB (2,000,398,934,016 Bytes)

Connection Bus : USB Write Status : Read/Write

Connection Type : External S.M.A.R.T. Status : Not Supported

USB Serial Number : 7CA0A8794644 Partition Map Scheme : Unformatted

Appreciate your help!

having the same experience as you here read up,,,,,,ok first up, some my book essential has an encryption on them...meaning if you remove your HD from the external enclosure it will be detected but the data will not or garbled. i recovered my data by using the fried pcb and used a data recover software then trow out the damage enclosure bought a new one put the HD in and reformat and recopy my data back in to it...

suggest goto western digital's community forum and search there. to see if your WB essential is encrypted type or not. and you might still see my post there and here is my post on how i recovered my data
