can't mount ntfs

[solenoid]

debian:/etc# mount -r -t ntfs /dev/hda /mnt/windows
mount: wrong fs type, bad option, bad superblock on /dev/hda,
or too many mounted file systems

i don't understand ??

/dev/hda is the device, you need to mount the partition, most probably /dev/hda1. You can check the output of 'fdisk -l' thats a lower case L.
