Hi, I'm having the same trouble and I initially got stuck in that I couldn't find where my Ubuntu 7.04 had the plug-in drive. I couldn't see it on the mount table, so I issued
which produced, among other things,
Disk /dev/sdb: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 1 30401 244196001 7 HPFS/NTFS
Then I did
as suggested. I'll let you know if I get stuck again!

Replace X with the correct device. So if you only have one othrt drive connected to the system it will most likely be /dev/sdb1. Before running the command make sure the device you are referencing is the correct device. The command will erase all data on the drive.
Also, if you want it to be a FAT partition replace mkfs.ext3 with mkfs.vfat.
Hope this helps.
