External drive is read-only, can't change

[nunix]

This is for 7.04.

I have an external USB drive that is being seen as read-only; I can't even change the file permission as root (by using gksudo nautilus and right-clicking on the icon). Doing some searching on my own I found a few directions for modifying fstab but this drive doesn't even appear to show up there. I don't use it that often, it's for backups.. and.. I actually need to do a backup. -.- So this is pretty frustrating..

# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# /dev/sda1
UUID=143c3cff-3c24-48d9-a989-e3e513ed4fb8 / ext3 defaults,errors=remount-ro 0 1
# /dev/sda5
UUID=37f844bb-46fd-4965-8ec8-5c1d893d3275 none swap sw 0 0
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0


But if I look under mount, the drive shows up as
/dev/sdb5 on /media/MEMORY LANE type ntfs (rw,nosuid,nodev,umask=222,utf8)

What the heck do I do so I can use my drive?
