Yes I know its bad to use raid 0 but I was using time machine just to try it out and backups will backup once or twice, then all of the sudden time machine will freeze, and the drive will no longer be recognized, and then the drive is hell to get working again. I have to plug it into a windows machine and use a norton tool to initialize it, and reformat it in ntfs, then reformat it in mac to make it useable again. I know everyone will say its the hardware but I assure you it is not. This happens with every drive I try, and every raid enclosure I try and it only happens in mac with time machine (and I tried reformatting the mac). Is there a known problem with time machine and raid 0? I searched the forums and didnt see anything. Anyone else have this problem?
