filesystem and mounting problems

[Geoff-lists]

Hi,

New user trying to mount some disks.  Can someone please let me know 
what I've done wrong.  Ubuntu 5.10 (Server) is what I have installed, 
and this mount task is the first thing I've done since the installation.

When I try and mount my disks I get the error:

[4296011.463000] VFS: Can't find ext3 filesystem on dev hde1.
mount: wrong fs type, bad option, bad superblock on /dev/hde1,
        missing codepage or other error
        In some cases useful info is found in syslog - try
        dmesg | tail or so


I thought I new what I was doing when I created the partitions on the 
disk. When I enter fdisk -l I get the response:

Disk /dev/hde: 80.0 GB, 800026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

    Device Boot    Start    End     Blocks    Id   System
/dev/hde1             1   9729   78148161    83   Linux


The entry in /etc/fstab is:

/dev/hde1   /mnt/80g    ext3    defaults    0   0

Thanks for your help,

Geoff
