I use fdisk.

first I su to root, then I

# /sbin/fdisk /dev/sdc

(for the third SCSI disk, in this example)

Then, once I am in fdisk, I would use the instructions fdisk provides,
to delete all partitions.

Then, I would create whatever new partitions I wanted.

Then, I would write the changes to disk.

Then, I would exit fdisk, and run mkfs on each partition I had created,
to format the new partitions in the filesystems of my choice.

Just make sure you select the correct device, or you might nuke the
wrong partitions. :)

Also... fdisk will not work unless you use /dev/[whatever]
If /dev/[whatever] mounts at /mnt/usb1, and you try using:

# /sbin/fdisk /mnt/usb1 ...it won't work, it will just give you an error
message.
