I've been running 8.10 for about two
weeks now. Everything has been going fine. I have the OS on a 13.5 Gig
drive and now that I've started adding applications and other things I
wanted to expand the storage space. I got an 80 gig drive to add
internally. It's a Western Digital and the jumper in the back is set
to 'slave'.

When I click on 'computer' the drive is shown. When I double click on
it to show it's contents (there isn't anything on it yet) I get a
error 'Unable to mount location can't mount file'.

When I try to open it with the file browser I get:
Could not display "computer:///SCSI%20Drive.drive".

So I did the sudo fdisk -1 in the terminal and got this:

Disk /dev/sda: 13.5 GB, 13578485760 bytes
255 heads, 63 sectors/track, 1650 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

Disk /dev/sdb doesn't contain a valid partition table

I'm assuming /dev/sda is the master drive, the one with the OS and the
stuff that goes with it.

And /dev/sdb is the 80 gig one I added.

After some googling I found these instructions...

sudo mkfs -t ext3 /dev/sdb

sudo su

mkdir /media/sdb

su myusername

sudo mount /dev/sdb /media/sdb

sudo chown -R myusername /dev/sdb

sudo chown -R myusername /media/sdb

That seems to have worked. My question is, there's a folder on the
drive called 'lost+found', can I delete this since I don't plan on
using it? or, if I can't delete it for some reason, can I use it to
store files? Why did that folder appear when there's already one in
the main 'file system' on the master HD?
