What do I need to write in /etc/fstab to allow the user to have full read and write permissions?

Options

# sync/async - All I/O to the file system should be done (a)synchronously.
# auto - The filesystem can be mounted automatically (at bootup, or when mount is passed the -a option). This is really unnecessary as this is the default action of mount -a anyway.
# noauto - The filesystem will NOT be automatically mounted at startup, or when mount passed -a. You must explicitly mount the filesystem.
# dev/nodev - Permit any user to mount the filesystem. This automatically implies noexec
# exec / noexec - Permit/Prevent the execution of binaries from the filesystem.
# suid/nosuid - Permit/Block the operation of suid, and sgid bits.
# ro - Mount read-only.
# rw - Mount read-write.
# user - Permit any user to mount the filesystem. This automatically implies noexec, nosuid,nodev unless overridden.
# nouser - Only permit root to mount the filesystem. This is also a default setting.
# defaults - Use default settings. Equivalent to rw, suid, dev, exec, auto, nouser, async.


This only applies to a linux filesystem, not windows.


Do you want the partition always mounted?

If so use auto, if you want the user to mount it use noauto,user,exec,rw options.

If you auto mount you can set the permissions on the mounted filesystem with chmod to allow users to write to it.

It's best to have a common group like 'users' and chown the folder like so..

chown root.users /mount
chmod 775 /mount

This would go along with the fstab as..

/dev/hd?? /mount ext3 defaults 1 1

if you need to mount filesystem which has no user rights(vfat,ntfs,smbfs,...) use this:
/dev/hdXX /mountpoint vfat rw,umask=0 1 1
if you need to let user mount/unmount it:
/dev/hdXX /mountpoint vfat rw,user,umask=0 1 1
if you allow users to unmount partition mounted by other users:
/dev/hdXX /mountpoint vfat rw,users,umask=0 1 1
if your filesystem has user rights(ext2,ext3,xfs,reiserfs,....) remove parameter umask=0 or read "man mount" and set it to some more useful value
