| ftdisk | System | 4 | Error |
There is a bad sector on one of the disks on one side of the mirror set. Your data security is at some risk. There is still a good sector on the other side of the mirror set, and the probability that the same sector number will go bad on both sides of the mirror is low.
To regain complete data security, do the following: (1) examine the event logs to identify which drive has the bad sector; (2) back up all data on that drive; (3) reformat the drive using the verify switch to map out the bad sector; and (4) restore the backed up data.
