I left out part of this (that I did after sending the message).
Apparently the problem isn't so much the flash drive as what happens
when the icon on the gnome desktop doesn't go away - it refuses to be
removed.
I can manually mount the flash drive to its proper mount point, and
access it through the icon, but when I unmount it, the icon doesn't go
away, and after that, until/unless I manually remount the drive again,
the icon doesn't work (and won't unmount - duh!).
Now I'm not sure if this is a gnome issue or a CentOS issue. If I log
out and log back in, the icon still doesn't go away (implicating the
OS), but when I reboot, all is well again, for a while....
Thanks.
PS: John, the drive was not actually mounted when this happened, so a dd
would not work, either - it didn't even matter if the drive was plugged
in or not - the icon was there and unusable/misbehavin'.
Thanks.
