    Having a 2TB in raid 1 with a 250gb drive

    Recently my hard-drive just came up, (via ubuntu) with around 252 million bad sectors. Its clearly and truly on its way out.

    I am thinking about purchasing a 2tb drive to replace the broken one.

    At the moment, my pc is a dell prebuilt with 2 x 250gb WD drives in raid 0.

    The 2 tb drive should be enough space and I dont want to waste the one remain drive. It would be better to have the two drives working as raid 1 so that the 250gb driveit backs up whats on the 2tb drive.

    But is that even possible?

    or is the best way is to keep them as raid 0 and have a 2.25tb drive?

    Finally, is the bad drive well and truly dead? I'd prefer to keep the data on it

    If I understand properly the bad disk is one of the two in RAID 0. If that is the case you need to backup everything NOW. If you lose that disk you will lose everything on the RAID 0.

    If your controller allows you to use two different sized disks as a RAID 1 pair the the 2TB disk will appear as a 250Gb disk wasting a heap of space.

    Personally, I would stick the remaining 250Gb disk in a cupboard and run with the single 2TB disk. I doubt you will notice any speed difference.

    Yes you are correct! One of the 250gb drives is basically gone. The thing is the pc does not even boot up to windows now. Not sure how I can even begin to back that thing up.

    So would you think running the 2tb and 250gb as raid 0, is a bad idea?

    In that case I would install the 2Tb as a single drive then install windows on it then with luck you might be able to see some of the data on the RAID 0.

    Yeah that sounds like the best option then, and I guess from there I can do partitions and make use of the other working 250gb drive I guess.
