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.
