[opensuse] Fdisk-ing a usb drive?

Hi all,

In the absence of any clear/easy way to split a large tar/cpio/pax backup over
multiple files, I'm thinking of repartitioning the USB drive I have and putting
a Linux-appropriate file system onto it. However, I just asked fdisk to take a
look at it, and it didn't seem very sure about itself. Obviously I don't want
to damage the drive's partitioning in a way that I can't recover it properly,
so I'm looking for input. This is what I saw:

linux:/home/simon # fdisk -l

Disk /dev/sda: [snip snip...]

Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sdb1 * 1 60801 488384001 c W95 FAT32 (LBA)

linux:/home/simon # fdisk /dev/sdb1

The number of cylinders for this disk is set to 60800. [... snip snip...]

Command (m for help): p

Disk /dev/sdb1: 500.1 GB, 500105217024 bytes
255 heads, 63 sectors/track, 60800 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

This doesn't look like a partition table
Probably you selected the wrong device.

Device Boot Start End Blocks Id System
/dev/sdb1p1 ? 46390 152334 850999312 65 Novell Netware 386
Partition 1 does not end on cylinder boundary.
/dev/sdb1p2 ? 48229 117156 553649047 6e Unknown
Partition 2 does not end on cylinder boundary.
/dev/sdb1p3 ? 193979 209336 123360830+ 49 Unknown
Partition 3 does not end on cylinder boundary.
/dev/sdb1p4 ? 23815 23815 3302+ ac Unknown
Partition 4 does not end on cylinder boundary.

Partition table entries are not in disk order

Command (m for help): q

The size information is right (at least broadly so; it's a 500GB drive as sold)
but the partition information sure does look wierd. So, my question is, can I
safely repartition this? Will fdisk mess it up? Can I restore it to "general
purpose" use (i.e. get it back to a FAT32 format) using fdisk afterwards. Or
should I be using some other partitioning tool entirely?

TIA,
Cheers,
Simon
