I was burned once by this sort of Foolishness.  (Some USB Drives even have
"Blinky Lights", to tell when Activity occurs).  I do the File Copy, it
comes back to a prompt right away.  But then, when I say "sync", it shows
how slow Access is, to writing to some of these USB Drives.

Never pull out a USB, until you are *SURE* it is safe to do so.  That was a
good lesson for me!
