But be careful, in the *general* case, modifying 
partitions is usually a destructive thing - ie it 
will destroy whatever is in the partition. Unless 
the editor explicitly supports resizing a 
partition (and the filesystem within it) then 
you'll need to do some manual work - it's 
something I've done a few times.
Assuming EXT2 or EXT3, you can do it by :

Make sure you have a backup/means of recovery if it goes wrong.
Check (fsck -f) the filesystem (resize2fs will refuse to work unless you do).
Resize (shrink) the filesystem with resize2fs.
Delete the partition.
Re-create the partition making sure that it 
starts in the same place and is equal or larger 
in size than the filesystem size.
If you didn't make the partition exactly the same 
size as the filesystem, resize the filesystem 
again to fill the partition.
You now have a smaller partition with the same 
files in it - just less free space.

WANTED: "Software CD ROM Kit" for Canon CLBP 
360-PS printer (Canon part no RH6-3612, or 
possibly RH6-3810, or RH6-3610 might do). I've a 
dead HD and need this CD so I can replace the 
disk and re-install the printer OS on it. If 
anyone knows where I might get hold of one I'd be 
grateful - requests to Canon drew a blank, it's 
been out of support for years.
Alternatively, if anyone has one of these and 
would let me image their hard disk ...
