Well, the blkid library, specifically, was getting confused. E2fsck

What about if th blkid library was to report some sort of

That would be a great help.
One thing that you might do for devices that are always present (which
generally means you're not changing them in your /etc/fstab often) is
to use a UUID= reference instead. They are definitely less convenient
than labels, but they are also much less likely to cause confusion by
having duplicately labelled file systems.
Granted, no one wants to *type* "mount
UUID=9e132c06-1fd0-4bbd-ad06-5995a8f45b26"; they'd much rather type
"mount LABEL=websites". But if the only place the a
UUID=... specification shows up is in /etc/fstab, it might be worth
Can I set the UUID value, with some descriptive
text,(something like a long label name), or is the UUID only
Then you can just zap the label on file systems that you only plan to
reference via UUID, and then that reduces the chances for confusion in

Try the list of Articles and Publications here:
I'm reading up on that stuff now.
The first link in the list is interesting
I think the reason the USB has SO MANY errors on the FS is
because I possibly unplugged it, before umounting it!
I understand that the umount command flushes any disk I/O
buffers back to the drive?
In theory, theory and practice are the same;
in practice they are not.
