Well, yes, but then what's inside the LVM partition is beyond me. I
guess your swap partition is in there but we cannot see it. I don't
like stuff I cannot see so I haven't used LVM.

There you go! You're a star!

The mount command:

[mark at Godzilla mark]$ mount
/dev/hda4 on / type ext3 (rw)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
usbfs on /proc/bus/usb type usbfs (rw)
/dev/hda1 on /boot type ext3 (rw)
/dev/hda6 on /home type ext3 (rw)
none on /dev/shm type tmpfs (rw)
none on /var/lib/jack/tmp type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
nfsd on /proc/fs/nfsd type nfsd (rw)
/dev/sda1 on /home/mark/Audio/audio1 type ext3
(rw,noexec,nosuid,nodev,user=mark)
/dev/sdb3 on /home/mark/Audio/audio2 type ext3
(rw,noexec,nosuid,nodev,user=mark)
/dev/sdc1 on /home/mark/Audio/audio3 type ext3
(rw,noexec,nosuid,nodev,user=mark)
/dev/sdb1 on /home/mark/music type ext3 (rw,noexec,nosuid,nodev,user=mark)

It's marked bootable by your DOS software. My input (if and when you
are ready) is to enter fdisk, blow the partition away, make one or
more new ones, format them, mount them, and then be done with the
gremlin on the other end of this chat named 'mark'. ;-)

CAUTION - Please read the man pages and proceed carefully here. The
following is from memory, but I do this fairly often to it's not
distant memory.

CAUTION 2 - If Rick or anyone more exerienced than me (almost
everyone!) says to do somethign different then OBEY them with a smile!
;-)

Here's how I think it would go:

fdisk /dev/sdb

p (to make sure you are on the right drive with one partition) 
d 
1
n
p
1
Hit enter a couple of times to make one partition the full size of the drive
p (to see your new partition before you commit)
w (to commit)
q (if necessary - I don't think it is. w drops you back to the command line.)

Look for any error messages. Sometimes a reboot is required. Happened
to me this morning in fact.)

At this point, if I got it right you'll have a Linux partition on the
drive the full size of the drive. You can make smaller ones if you
want to.

Now you format it with ext3

mke2fs -j -L newbackup /dev/sdb1

BE VERY careful here not to type /dev/sda1 or you'll blow away your
existing drive and have to rebuild your system.

mount /dev/sdb1 /mnt/newbackup

And you're up and running. We can handle putting the mount into
/etc/fstab later if you want.

Cheers,
Mark
