How to unmount hard drives:

This is so that You can be sure the drive won't be written to.
Open a Terminal session.
Get a list of mounted devices by typing "mount" (without the quotation marks) and pressing [Return].
One or more of the list will contain the drive partitions You have mounted, such as 
	/dev/hdc1 on /home/kev/1_mount type ext3 (rw)
To unmount hdc1 type:
	umount /dev/hdc1
Note the command is "umount", not "unmount".
