cat /proc/partitions
If the new device is seen by the computer you will see a few messages come up. After a few seconds, if the drive is healthy enough, you will see something about a new device. Hit CTRL-C to get out of the tail command and run cat /proc/partitions again (hit cursor up twice at the command line to repeat previous commands you typed in) tail -f /var/log/kern.log
