How to mount ntfs partition so a group can write to it?
 

I have an NTFS partition which is mounted by fstab at bootup.

User can read from it, but not write to it.

Root can read and write to it.

I want to set the mounted NTFS parition so that a group can write to it, and then I can add users to that group.

Any ideas?

you really shouldn't be writing to a NTFS partition. It's not safe, it may corrupt data. There are some projects that are supposed to be able to write to NTFS, but I think they are still experimental as well.

Sorry, just realised its not NTFS, its fat32 !

Use the gid and umask options to mount, e.g. if the group you want to have write access has numeric ID 500:

mount -o uid=0,gid=500,umask=002 <device> <mount point>

You can add this to the options field in /etc/fstab if you have this mount set up in there, so the options get applied whenever you mount it.

Basically:
-- MSDOS based filesystem don't do *nix style permissions, so Linux fakes it for you.
-- You use the uid and gid options to determine owner and group of files on vfat volumes.
-- The umask gives what permissions are denied. A umask of 002 denies no permissions for user and group, and denies write permission for others.
