External USB hard disk aint working/mounting

Hi all,
i have this western digital 80 gb external usb hard disk. But it isnt mounting in mandriva 2008. when i connect it the konqueror windows pops up with following error message ::
PHP Code:
usb hard disk wrong fs type,bad option,bad superblock,missing codepage errorCheck dmesg|tail 
dmesg | tail gives :

PHP Code:
sd 9:0:0:0: [sdbWrite Protect is off
sd 9
:0:0:0: [sdbMode Sense03 00 00 00
sd 9

FATbogus number of reserved sectors
Can't find a valid FAT filesystem on dev sdb1. 
If i try to mount it manually it throws up this error :

PHP Code:
sudo mount -t ntfs-3g /dev/sdb /mnt/disk/ -o rw
NTFS signature is missing
Failed to mount '/dev/sdb'Invalid argument
The device 
'/dev/sdb' doesn't have a valid NTFS.
Maybe you selected the wrong device? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?

sudo mount -t ntfs-3g /dev/sdb /mnt/disk/ -o rw

it should be sudo mount -t ntfs-3g /dev/sdb1
you must specify the partition number sdb1 or sdb2 or etc..
try fdisk /dev/sdb
view existing partition
recreate partition table if no data on hdd
create a filesystem on partitions created

Ohh im really sorry for a stupid mistake. But i forgot to mention that mounting hasnt been an issue.
Like after mounting it when i tried to play some content via command line :::
PHP Code:
kaffeineKXineWidgetPlaying: /mnt/disk/Smallville3/
KXineWidgetxine eventchannels changed
system call fstat
Input/output error
system call fstat
Input/output error
system call fstat
Input/output error
system call fstat
Input/output error
system call fstat
Input/output error 
also ls couldnt find any files
PHP Code:
[rusha@localhost Smallville 3]$ ls
cannot open directory .: Input/output error 
also mount gave folowing output
PHP Code:
[rusha@localhost Smallville 3mount
/dev/sdb1 on /mnt/disk type fuseblk (rw,nosuid,nodev,noatime,allow_other,blksize=4096
Though its giving input/output error on ls but df gives
PHP Code:
[rusha@localhost disk]$ df -grep -i sdb1
/dev/sdb1              75G  6.0G   69G   8% /mnt/disk
