Hi All,

I does dm-crypt work with plain USB drives?

I ask, as I attempted to encrypt an entire USB drive and was able to access=
 and read/write data.
However, when I I attempt to umount the drive, I'm consistently told that t=
he drive is busy.

I've tried to umount /mnt to no avail.  In KDE Dolphin, the drive shows up =
in removable drives and disks.

Is this a dm-crypt, udev, or other issue?

Thanks in advance,
-J. Johnson
