I'm working on a Friend's WD MyBook "1TB" HDD that is not mounting. When I got in to it, I discovered that it is really 2 500GB HDD's set up as RAID-0. It appears that the drives themselves are fine, but that the logic board has failed.

My questions is this: can I re-initialize the RAID-0 using software RAID so that I can recover the data to another drive? If so, how and which software RAID would be best (Preferably open source. any platform OK).

Have you tried calling Western Digital's tech support? They may have some good ideas. – Ƭᴇcʜιᴇ007 Aug 13 '10 at 22:49
Not yet. Their working hours haven't corresponded with my work on the problem. – Ben Aug 15 '10 at 14:44
Another reason Raid 0 is a bad idea. I hope you get your data. Are you sure it is not Raid 1 (mirror)? – Moab Sep 18 '10 at 15:10

Prospects are not good. By far your best best is to find a new logic board and mount the drives in that, and then you MIGHT get access to your data. It is also possible, though very unlikely, that the meta-data format used by the hardware is actually a software RAID format that's recognizable by something. Hardware RAID uses a variety of metadata formats that is exceedingly rarely interchangeable outside of the vendor's hardware. Or even within their hardware.

Your best bet is to find a replacement for the logic board.

It should be possible, the key feature you'll want to look for is to Import the configuration from the drives. If you try to set up a new RAID array without importing from the drives, you'll probably lose all your data.

Alternatively, you could seek the assistance of a magenetic recovery company for about $1000.
