[TriLUG] e2fsck under cron gets retcode=8 operational error

[Joseph S. Tate]

Ok, stupid question time:

Why do you bother to umount at all?  Why not just do it at shutdown?

Why haven't you already turned off mount count and time based checking
on that volume (from another system perhaps) if you're forcing a fsck
every hour anyway?

Why are you running fsck so frequently?  Won't that prematurely age
your thumb drive?

Why are you using ext2/3/4 on a thumb drive instead of a FS built for
flash storage so that you get error detection and correction as a
feature of the FS instead of having to kludge this whole convoluted
thing together?
