If you accidentally run a recursive delete like Rich did then your data is gone. RAID will not let you recover the deleted data. If a controller goes stupid or glitches during a write then at least one disk will have garbage data on it. RAID will not protect you from this. If a RAID rebuild uses that garbage data as the mirror "master" then you will really loose all of your data. To the contrary of your assertion, RAID will blindly and silently and automatically destroy your data. -- Rich P. _______________________________________________ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss
