Recover overvoltaged WD MyBook
October 13th, 2009, 9:21
I put the adapter for my Asrock Ion 330 (19V) into the same-sized connection of my Western Digital MyBook (12V).
I have the Mirror Edition, 2 x 1TB. The leds in front started flashing immediately, I pulled the plug but the damage was done. When I put the right plug in the back, the leds started flashing again and the drives would not spin up.
I had it set up in RAID0 using the WD Drive Manager Tool, so I was able to use its full capacity. (At least, I think it's RAID0, maybe in some proprietary form, or JBOD?). The file system is HFS+.
After some testing with another (single drive) HDD SATA enclosure, I figured out the PCB of one of the drives got fried: one drive started spinning and showed up in Disk Utility (OSX) and Drive Management (WinXP), the other one didn't. With the PCB from the first drive connected, the second one started spinning too, and showed up in Disk Utility/Drive Management. However, they did not get a drive letter assigned and were unreadable.
I have high hopes the data is still on them, the question however is how to get it off there with the soft- and hardware I have available:
- I have already bought a second 2TB drive (the MyBook disks had about 1.6 TB on them).
- I have a 640 GB drive for backup purposes I can use temporarily. (It's this enclosure I used for testing the damaged drive.)
Since I can only access one of the two MyBook drives at a time (only one working PCB), I tried making a dmg image of the other one, using Disk Utility. I then tried Raid Reconstructor to see if it could repair the RAID, but it couldn't find the paramaters (entropy 93 etc.). Right now I'm in the process of letting Raid Reconstructor itself (in WinXP) make an image (has been busy doing that for the last 16 hours or so). I'll try if that works out next. To do so, I'll put the image on the new 2TB drive and also connect the MyBook drive with the working PCB. That way maybe I can slowly pull off the data and put it file by file on a DVD or my internal laptop drive. I just hope Raid Reconstructor knows how to deal with HFS+.
If this procedure fails, are there any other options I have?

Hi Stanley,
This procedure is guaranteed not to work
These drives need special equipment to work with; they have adaptive data on the pcb, and if these are burned you cannot access the data. Unfortunately nothing that you can do yourself.
I'm also in Belgium. If you can send me the drives, i'll make you an offer for the recovery.
You can also PM me.
Best regards,
Dobre

Agree, these drives PCB's CANNOT be fixed without specialist equipment & knowledge.
Dobre comes with my recommendation too.

Hi,
excuse me for the dumb question, why are using Raid reconstructor? U wrote it was a Mirror edition or something like that...
Then the content of the two drives are probably equal, so u just need one drive to gain access to the data....
