Make a new directory in /media:-
sudo mkdir /media/forced

and then post the output of:-
sudo ntfs-3g /dev/hda5 /media/forced

If the mount does not work then we can find out the problem using the error message.

fation@fation-desktop:~$ sudo ntfs-3g /dev/hda5 /media/forced
fuse: mount failed: Device or resource busy
FUSE mount point creation failed
Unmounting /dev/hda5 ()
fation@fation-desktop:~$

It seems that hda5 is already mounted:-
/dev/hda5 /media/hda5 fuseblk rw,nosuid,nodev,noatime,allow_other,default_permissions,blksize=4096 0 0

Did you check in the /media/hda5 folder to see if that is your Windows partition?

i have 2 HD's and in both of them i have windows xp but when i go to the boot to select the OS there is only one winzoz and it doesn't function,there is a request for me to register the product and the pc get restarted,however i don't use winzoz anymore,so in /media/hda5 i have the folder windows and the windows programs the same at the /media/hda1 windows folder and windows programs!The space is already occupated by both the windows,but i'm searching the other partition of 80 GB :(

solved reinstalling ubuntu and erase everything at last i've got my 250 GB (j.k i've done a backup of all)
however thanks a lot to all the people

peace & love brothers
