ok, in your fstab file you should have something like this: let's call the NTFS partitions hda2 & hda3.
/dev/hda2 /mount/point1 NTFS defaults,noauto,user 0 0
/dev/hda3 /mount/point2 NTFS defaults,noauto,user 0 0
This will allow a user to mount the partitions once the system is booted. That user will then be the owner of the devices.
If you want them to mount during boot, then remove the noauto option. Note that if you do this, user ROOT will be mounting the drives during boot, so ROOT will have to unmount them if you want to remount them as a user. Also make sure the mountpoint is accessible by the user also, and not only ROOT. You could also in this case assign a UID= to the devices, making them mount and owned by user <uid#>
If you still have problems, you may need to make sure the etc/fstab file is readable by the user, not just ROOT.
Let us know if this works.
Also, check the man page for full details: type 'man mount' or 'man fstab'
