    Hi,
    I have a Raid 0 set-up on my PC. I think one of the drives is dying. Is it possible to switch from Raid 0 to Raid 1 at this stage?

    I have a full system back-up on an external HD using Acronis.

    This is on a Dell machine.

    Thanks in advance.

    How is RAID 0 done, software (which OS ) or hardware ( which controller )

    As far as I know it is done via some intel unit on the motherboard(if that makes sense). There is an intel prompt on start-up for RAID configuration.

    I am running XP SP2.

    go into the intel bios utility on boot up, and i'm sure you will find out then whether you can convert to raid 1 or not by seeing what menu options are available to you................

    generally the answer is no. All you can do is backup your data, and start from sctratch.

    Thanks for the responses.

    Is it easy to diagnose which drive is failing?

    Also is it a case of just replacing one or both and rebuilding the system?

    Thanks again

    you have no redundancy with raid 0, so if one drives dies, the system will not boot.
    is there no raid utility installed that will show you what drive is about to fail?
    also check the windows system event log to see if there are drive read/write errors there.

    In Raid 0, half a file is on each disk so if he takes one away, he'll loose half of his files which will mean he'll loose everything.

    actually depends on the stripe size, if it's 64K then files less than 64K will be on one disk or the other. You will of course loose the complete FAT/NTFS tables so you won't be able to find files unless you search the surviving drive bytewise and even then you're only likely to find plain text files unless you are a hero or machocist or have a super duper recovery CD.

    Backup, reinstall, restore
    Backing up would require a lot of storage so before you do , ditch the junk so you are only backing up stuff you can't retireve elsewhere.
