What you need to do is replace the drive that has alegedly failed and do a rebuild. Providing you haven’t done anything else to it all your data should still be there.
I have a MyBookWorld II with the blue rings. Inside it has 2x500GB disks. I had to replace drive A a couple of weeks ago and after the rebuild all my data was there fine. I couldn’t get exctly the same model drive as was in there, but I replaced it with a WD5000AAKS which cost me about £40, so probably $80 Canadian.
If you take a look in the WD KnowledgeBase you should look at article 1464 to replace the drive, then article 1496 which tells you how to rebuild the mirror array.
Don’t know what your level of experience/confidence is, but you could also try putting the failed drive in a SATA caddy attached to a PC which has ext2 drivers installed and see if you can recover the data that way
Dunno, but I couldn’t access the data on the unit after the drive was reported as failed. I guess if you took the good drive out, put it in a SATA caddy and attached it to a PC with the right drivers you may be able to pull all the data off, but I didn’t wan’t to risk screwing anything up so I just did it by the book.
However, after the recovery was complete and I knew my data was safe I just tried putting the “failed” disk in the SATA caddy for a laugh. I expected it to just be dead as a dodo, but to my surprise it powered up and by mounting the correct partition using ext2 drivers I could see all my data sitting there. I had it mounted readonly, but I copied some stuff off to another disk and it was fine. Maybe the original problem was overheating or the drive is flakey in some other way? It couldn’t be a WD scheme to sell more drives, no surely it couldn’t be that =;~)
