Can't find a valid FAT filesystem on dev

[leord5]

I have problems mounting a VFat hd drive. I get
VFS: Can't find a valid FAT filesystem on dev hdb

# dmesg | grep hdb
ide0: BM-DMA at 0xffa0-0xffa7, BIOS settings: hdaMA, hdbMA
hdb: ST34311A, ATA DISK drive
hdb: max request size: 128KiB
hdb: 8452080 sectors (4327 MB) w/256KiB Cache, CHS=8944/15/63, UDMA(66)
hdb: cache flushes not supported
hdb: hdb1
VFS: Can't find a valid FAT filesystem on dev hdb.
VFS: Can't find a valid FAT filesystem on dev hdb.
VFS: Can't find a valid FAT filesystem on dev hdb.

and when I try to mount the disk I get :
# mount -t vfat /dev/hdb /mnt/wind/
mount: wrong fs type, bad option, bad superblock on /dev/hdb,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Do you have any clues on what might cause this?
In windows the disk works fine.

oh i see the problem you tried a wrong command
hdb is only identify the disk and hdbX (wher X is a number X=1,2,..)
is identify a partition on the disk.
You can't mount a disk just a partition
So figure out the number of the partition and mount it

use "fdisk -l /dev/hdb" to list the partitons
and mount the correct partition

mount -t vfat /dev/hdbX /mountpoint
