    I have a RAID-1 in my computer currently. This is the first RAID I've setup before.

    I was just wondering, how do I check the health of each drive?

    Will the controller let me know during boot-up that a drive is down? Is there a program to scan each drive?

    Depends, is it hardware or software raid? What is your OS?

    I guess it's hardware since you mentioned a controller. I don't know much about hardware RAID. The only card I ever had I didn't end up using.

    A way to check might be to shut down your computer and then pull out a drive. Boot and see what happens.

    BIOS may also indicate the status of your hard drives.

    If it's a Linux software RAID, you can cat /proc/mdstat to find out the status of each drive.

    But I'm guessing it's not :mamoru:

    yes, at boot it lists the number of physical drives, its state, the number of logical drives, and its state.

    haven't seen any controller that does NOT report this at boot.

    within the os that's diff story. depends on the driver or daemon you have.

    Mine doesnt, just lists number of logical drives. If something is amiss it freaks out and starts beeping.

    There is a management tool that will show me drive health though.

    I'll check what I have next time I boot up.

    I know a screen comes up briefly that lists the two drives and the Raid volume. Goes by too fast to read much though. lol

    It's a hardware RAID. Controller came on the mobo. I'm running windows xp
