Assuming something relatively current such as RHEL 4U3, 4U4 or Fedora
Core 5 or 6, the drive should show up automatically in the /media
directory.  The directory it's mounted as will reflect the filesystem
label (if any).  For example, if the drive has a filesystem label such
as "FlashData", then it will probably mount as "/media/FlashData".

If there is no filesystem label (such as a DOS- or VFAT-formatted
drive), then it will probably show up as "/media/disk".

If it doesn't automatically mount, then the raw device name will be
"/dev/sdDP" where "N" will be "a" if this is the first SCSI disk, "b"
if it's the second and so on (NOTE: SATA drives are also considered
SCSI drives in Linux).  The "P" identifies the partition number in the
drive, starting at 1.  You will have to manually mount the drive by
first creating a mountpoint as the root user:

	# mkdir /media/mydisk

Then executing a mount command.  Assuming this USB disk is the second
SCSI drive (because you already have a SATA drive) and that the first
partition on the USB drive is the partition with the file system (most
likely):

	# mount /dev/sdb1 /media/mydisk

Voila!  Don't forget to unmount it before you unplug it:

	# umount /dev/sdb1   --OR--   # umount /media/mydisk

Either command will work.
