    I believe my Raid-0 array is about to fail. I'm getting random ejects from one of the slices, which is an internal drive on the Mac Pro. Once it ejects, it unmounts the array and makes the system give me a "drive ejection" alert box.

    I already backed up all my data. I don't even know which one is the bad drive (or if the problem lies indeed in a bad drive, but it certainly doesn't appear to be a bad connection). Disk Utility finds no errors at all. Smart status is verified for all drives.

    This is a brand new drive which I just bought less than a month ago. Model is Seagate Barracuda ST2000D001

    How else can I check for errors?

    Non-enterprise class drives for RAID0 is pretty sketchy, in my experience. I believe that Barracuda is a green drive which is even less suited for RAIDs. Keep backing up!

    Words from a wise man. Especially the first and last part, even the part in between too.
