Along with the -n another suggested, consider two more possibilities. Probably smartdrive capable disks, you can use the smartd and smartctl (man pages in section 8) to have non-intrusive monitoring and diagnostics active. Then reports can be generated. Another possibility, if allowed by you situation, is to remount the drive ro (IIRC, mount -o remount,ro <you device or mount path>. No one will be able to write to the drive at that time, but you should be able to run the fsck and (IIRC) do repairs if desired. HTH -- Bill
