[LAU] [OT] recommended partition manager ?

[Dave Phillips]

Greetings,

My laptop has seen a variety of installs over the past year, and I now 
have a fair amount of delegated but unused disk space. Is there a 
recommended procedure or program that can re-acquire that space for my 
Karmic installation ? I've never repartitioned a disk *after* an 
installation, so I'm a bit nervous about the process. Advice is needed 
and welcome.

TIA,
