Drive caddy jumper issues - /dev/hda /dev/hdb

Some students discovered that their hard drive caddies gave errors when
accessed as "/dev/hda" in the labs; but, they worked when accessed as
"/dev/hdb".

This is a hardware jumper issue with your hard drive inside the caddy.

If you have jumpered your hard drive in your caddy as "Master", it will
always appear in the Algonquin labs to be /dev/hda (first disk on the
first IDE controller).  Otherwise, your drive is a "Slave" and it will
always appear as /dev/hdb (second disk on the first IDE controller).

The "fdisk -l" command will list all the hard drives and hard drive
partitions about which Linux knows.  The output will tell you whether
your drive is /dev/hda or /dev/hdb.  (At home, it may even be /dev/hdc
or /dev/hdd or something else.)

Be aware of how your drive is jumpered inside your caddy, and use the
correct device pathname.
