Really hoping you can help me out here, it seems that this forum is the best place to recover a seemingly dead hard drive.
A quick description of the situation: my brother had a WD MyBook Studio 2TB which was attached to his MacBook Pro (HFS+ etc.). Long story short, it looks like the hard drive broke because of overvoltage (he lives in a country where the electrical system is pretty dodgy). The circuit in the hard drive case has died, but the hard drive itself turns on when it's connected to another case or internally.
I connected it to a Windows machine to run TestDisk on, but I made the mistake of clicking "initialise" thinking that it wouldn't actually write anything to disk.
I ran TestDisk ("Deep Search"), it took 3 days, but finally got stuck at 93%, after having found the following partitions:

Now, I don't really know how to interpret the results, or what to do. According to the internet (and considering this is a GPT/HFS+ hard drive), I should connect it to a Mac, and use the information from TestDisk in pdisk to rewrite the partition table.
Could you tell me how you think I should proceed with the information I've provided?
Thanks in advance,
Nicolas
