RAID 0 is striping - it is not good insurance and in fact doubles your risk of losing data since if either drive dies, you lose data.

Bad idea. Assuming you meant mirroring and not striping, you do have your partitioned data on a mirror member but remember that the MBR is not automatically mirrored. You could try running the badblock utility on the failing drive and try to map the bad block out, but in my experience (going back about 25 years), once a drive starts to fail, it is on its way down and you get a another day or month out of it, but you will lose the drive - it's just a matter of when. Bottom line: 1. Check to make sure you're mirrored and not striped. 2. Replace the drive. -- Ed Wilts, RHCE Mounds View, MN, USA mailto:ewilts@xxxxxxxxxx Member #1, Red Hat Community Ambassador Program
