Problem mounting 1 FAT32 partition (but others are OK)

I have a dual boot system (Win98 / Debian) and I'm trying to mount a known good fat32 partition under linux. I keep getting the "wrong fs type, bad option, bad superblock" error...

/dev/hda5 is the partition I'm trying to mount:

Code:

root@ttyp0[mnt]# fdisk -l

Disk /dev/hda: 60.0 GB, 60022480896 bytes
255 heads, 63 sectors/track, 7297 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hda1 * 1 1952 15679408+ c W95 FAT32 (LBA)
/dev/hda2 1953 7297 42933712+ f W95 Ext'd (LBA)
/dev/hda5 1953 6612 37431418+ b W95 FAT32
/dev/hda6 6613 7297 5502231 b W95 FAT32

root@ttyp0[mnt]# ls -la /mnt/hda5
total 2
drwxr-xr-x 2 root root 1024 Jul 14 20:19 .
drwxr-xr-x 13 root root 1024 Jul 14 20:19 ..
root@ttyp0[mnt]# mount -t vfat /dev/hda5 /mnt/hda5
mount: wrong fs type, bad option, bad superblock on /dev/hda5,
or too many mounted file systems
root@ttyp0[mnt]#

Any ideas? I can access this partition with no problems under Windows (it's my D: drive).

I also have the output from sfdisk if that helps:

Code:

root@ttyp0[mnt]# sfdisk -V -l -x  /dev/hda

Disk /dev/hda: 7297 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0

/dev/hda: OK
root@ttyp0[mnt]#

On the other hand, /dev/hda6 (Windows drive E:) mounts with no problems:

Code:

root@ttyp0[mnt]# mount -l
...
/dev/hda6 on /mnt/hda6 type vfat (ro,nosuid,nodev,umask=000,uid=1000,gid=1000)
...

I've tried this under debian and knoppix, with no luck.

Code:

root@ttyp0[mnt]# uname -a
Linux Knoppix 2.4.22-xfs #1 SMP Fr Okt 3 20:36:25 CEST 2003 i686 GNU/Linux

Any help appreciated,

Or mabey you should try formating the partition again using a linux formatting util (windows and linux formating utils should be identical, but mabey its just the formating was done wrong
