Can't get data off of former RAID hard drives

    In January I had gone on a trip out of state for a week, when I left my computer was running fine. I shut down the computer, and turned off the power strip before I left. The computer had RAID 1. When I came back I noticed I had an extra hard drive, and I noticed the RAID had failed for some reason (I don't know why, it was shut off the whole time).

    Long story short, the computer was getting old and I decided to put the drives into a new computer, but when I did the computer did not recognize them. I booted the computer with a live cd and it said something about it being an unknown raid configuration, or something like that. All windows wants to do with the drives is format them.

    I had set up the raid just so it would be almost impossible to lose the data on them, is there a way to recover the data? Can I make the drives usable without formatting them?

    With RAID 1 the drives are each a complete duplicate of the other. I would remove one drive from the RAID and connect it as a secondary drive to a system without RAID. If that doesn't work, try the other drive. If that doesn't work, you might try some data recovery software.

    I had a similar situation recently and Easy Recovery Pro did a superb job of recovering absolutely everything.

    Do you still have the old pc (where the disks where in RAID?)
    Maybe that machine will be able to recognize them and you could copy them over to the new pc.

    I don't have much experience with RAID so someone correct me if I am wrong, but I think that unless you hook the drives up to the exact same type of controller the disks will need to be formatted and the array needs to be rebuilt.

    The only redundancy RAID 1 has is hard drive failure.
    If one drive fails then you can boot from the second, this must be done on the machine the array was built on, putting them in another machine will not work.
    RAID of any flavour is NOT!! backup
