Can't change the read permissions on an NTFS partition as root?
 

I've just recently installed Slackware 10, and after I mounted my NTFS pertition, I was unable to access it except as root. Even when logged in as root I am unable to change the folder permissions. Help?

post your /etc/fstab

/dev/hda6 swap swap defaults 0 0
/dev/hda5 / ext2 defaults 1 1
/dev/hda1 /windows ntfs ro 1 0
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0

You can not change folder permissions when the partition is mounted.

Change to
/dev/hda1 /windows ntfs umask=222 0 0

try something like this:
/dev/hda1 /windows ntfs ro,users,umask=022 1 0
