add the drive. boot up the system. typing "dmesg | grep hd" or "dmesg | grep sd" will show you the drive device (something like /dev/hdb or /dev/sdc, depending on the drive type and controller you plugged it into). type "fdisk /dev/hdb" or whatever, and create your partition(s). type "mkfs.ext3 /dev/hdb1" or whatever the partition is to create a filesystem. add /dev/hdb1 to /etc/fstab (use the other lines as examples) to mount it on boot.

you can probably use gparted or something in place of the fdisk and mkfs commands, but you should learn to use the commandline tools. otherwise, i'll taunt you in public. after all, you have over four hundred posts here.

Hello :),

A longer, more extended check of one partition
--> badblocks -n -v /dev/hda1

A quick check of only one partition
--> badblocks -v /dev/hda1

To find additional info about your hard disk, use this command:

--> hdparm -i /dev/hda
