Error when mounting Windows disk

[patrik]

I get the following error message when I try mounting a Windows disk on my Linux computer.

FAT: bogus logical sector size 0
VFS: Can't find a valid FAT filesystem on dev 16:01.
mount: wrong fs type, bad option, bad superblock on /dev/hdc1,
       or too many mounted file systems

fdisk -l gives the following:

Disk /dev/hdc: 41.1 GB, 41110142976 bytes

Units = cylinders of 16065 * 512 = 8225280 bytes

I had a CDROM mounted as master on the secondary IDE channel when I installed Linux. Afterwards I unplugged it and put in a Windows disk as master using cable select. That's the one on /dev/hdc above, that I have problems mounting.

I added a line to /etc/fstab so that it looks like

LABEL=/                 /                       ext3    defaults        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
none                    /dev/pts                devpts  gid=5,mode=620  0 0
none                    /proc                   proc    defaults        0 0
none                    /dev/shm                tmpfs   defaults        0 0
/dev/hda3               swap                    swap    defaults        0 0
/dev/fd0                /mnt/floppy             auto    noauto,owner,kudzu 0 0
/dev/hdc1		/disk/hdc1		vfat	defaults	0 0

and created the mount point: mkdir -p /disk/hdc1

ls -l on /dev/hdc1 gives

brw-rw----    1 root     disk      22,   1 Jan 30  2003 /dev/hdc1

For reference, df gives

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda2               710368    463092    211192  69% /
/dev/hda1                39979     14831     23084  40% /boot

/dev/fd0                  1424       244      1180  18% /mnt/floppy

All actions done as root. What did I forget? I do something similar (mount a Windows partition) on another computer and it works, but there all partitions are on the same disk.

How can I see how many mounted file systems I can have, if that is the error?
