    Check the specs. It specifies that it is NOT compatible with TM.
    OSX needs to have this reformated, default format is windows. Did you reformat it? May be then?
    Basically Time Machine disks need to be the right format and I am not sure how easy it will be with the Raid. I think it should be possible on mac-mounted soft raided drives, but on external box? The system on that box which creates the raid needs to be TM compatible and WD is not specifying it. So chance is it will not work and it is not Apple fault.

    I assume it is formatted for NTFS which OSX can NOT write to out of the box (it can read, but not write to). This is true for all "non-Mac" drives on the market. Just format to HFS and it should be fine.

    Thanks! I will reformat upon arrival

    And thanks Pieterr for the link to the manual.

    The drive didn't arrive yet. I ordered it (ok even if it couldn't do TM) since I have a NAS on the LAN for my macbook pro's TM backups. There is space and I'll use a separate NAS volume for TM for the imac.

    I've never splurged for RAID 1 (redundancy) for any of my systems. I'm looking forward to having safer storage which will reduce my exposure when I'm lazy and don't backup to offsite as frequently as I know I should!
