when next it happens, you might try (note, you are playing with a root tool, it may or may not work
as a normal user):
/sbin/fuser -m /media/myFlashDrive/
or
/usr/sbin/lsof  /media/myFlashDrive/

What can be *really* frustrating, is when those commands (with any options) don't give any info, and
you cant get it unmounted (granted I have not seen that since using Fedora 1 machines with DRBD as
an NFS server).

man fuser
"-m ... All processes accessing files on that file system are listed. ..."

man lsof
