(1) The drives generally arrive with fat32 file systems, when first attaching the drive, allow the workstation to mount the drive. Then unmount ether by right-clicking over the drive icon on the desktop and selecting 'eject/unload' or issue the umount /media/(drive) command.

(2) To locate the disk/block device:

	cat /proc/partitions

major minor  #blocks  name

   8     0   78125000 sda
   8     1     192748 sda1
   8     2   77931315 sda2
 254     0    1048576 dm-0
 254     1   10485760 dm-1
 254     2    8388608 dm-2
 254     3   10485760 dm-3
 254     4   26214400 dm-4
 254     5   77931315 dm-5
 254     6    1048576 dm-6
 254     7   26214400 dm-7
 254     8   10485760 dm-8
 254     9   10485760 dm-9
 254    10    8388608 dm-10
 254    11     192748 dm-11
   8    16  244198584 sdb
   8    17  244196001 sdb1

 * On most of our single (internal) drive workstations,  
the drive will show up as device sdb. Note the 
size of the drive (244198584) for identification.

(3) create the filesystem and label:

sudo mkfs -t ext3 -L calusb /dev/sdb

(4) re-attach the drive to the workstation, Ubuntu will automount the drive. Create the scratch area and make the folder accessible by all:

	cd /media/calusb
	sudo mkdir /scratch
	sudo chmod 777 /scratch
