I plugged it into my windows machine and formated it in FAT32 (it was in FAT), but it did not seem to make a difference. It still shows up as sda. I decided to use some of the commands on another spare usb drive I had laying around and the results seem wierd to me.

These results are for the drive I have been using.
lsusb
Bus 003 Device 001: ID 0000:0000
Bus 003 Device 002: ID 0ea0:2168 Ours Technology, Inc.
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

dmesg | grep -i "SCSI device"
SCSI device sda: 512000 512-byte hdwr sectors (262 MB)
SCSI device sda: 512000 512-byte hdwr sectors (262 MB)

These results are for the spare drive I tried.
lsusb
Bus 003 Device 001: ID 0000:0000
Bus 003 Device 008: ID 0ea0:6803 Ours Technology, Inc.
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

dmesg | grep -i "SCSI device"
SCSI device sda: 512000 512-byte hdwr sectors (262 MB)
SCSI device sda: 512000 512-byte hdwr sectors (262 MB)
SCSI device sdb: 129024 512-byte hdwr sectors (66 MB)

It seems wierd to me that the only thing that changed when using lsusb was the device number and the number after the colon. Shouldnt the message "Ours Technology, Inc." change? Also when using dmesg | grep -i "SCSI device" the old references to the other usb drive are still there and the new one is sdb. I am completely confused by this. I take it that if no one else is having trouble with this than I must have messed something up. Should I format, reinstall and see if I can get it to work than or is there something else I can try. Also, what difference does it make if I have the usb drive plugged in when I boot up? Thanks again for all of your help, I dont mean to be a nuisance, just trying to learn what I can.

OK, try this approach then:

Boot up DSL.

Download the dosfstools extension from the "System" section of the MyDSL menu.

Open an xterminal window and type:

sudo su
cfdisk /dev/sda

Then use cfdisk to create a new partition table and create a new partition that is the same size as your available free space. Then write the new table and exit cfdisk

Then type:

mkdosfs /dev/sda1

and it should format your newly created partition with a DOS (FAT) file system.

Hope this does it.

Ok, I tried

sudo su
cfdisk /dev/sda

I received two different kinds of errors:

FATAL ERROR: Cannot open disk drive
Press any key to exit cfdisk
(light on drive does not come on)

or

ERROR: Bad primary partition 0: Partition begins after end-of-disk
Press any key to exit cfdisk
(light on drive blinks)

So it doesn't give you the choice to create a new partition table after the second error message?

If not, maybe it is possible to create a new table with another program like fdisk.

Will need to do some research on this one...
