If you're using Red Hat 9, as you suggested in one of your earlier threads, then please take the advice and install a newer distribution. Also, looking at your posting history suggests that you do not reply to your threads. Please do so, as people have been trying to help you and it's impolite to just ignore them.
With regards to the particular problem you're having:
1. Are you sure you're trying to mount the correct partition, i.e. are you sure it's /dev/hda1 for example and not something else?
2. Are you sure you're using the correct filesystem type, i.e. are you sure it's an NTFS partition rather than a FAT one?
3. Post your fstab, partition list (which you can get by running "fdisk -l") and any other error messages you get when trying to mount.
