[NTLUG:Discuss] Disk partitions under linux

[Leroy Tennison]

I have a 120GB Seagate hard drive which I use for experimentation, right 
now I have several distributions installed and set up for multi-boot 
from a single menu.  There are two primary partitions (/boot for 107MB 
and a user data partition for 3010Mb) followed by an extended partition 
(80GB) containing: 10.7GB (CentOS 5), 1077MB (swap), 10.7GB (SuSE 8.2), 
10GB (Fedora Core 5), 10GB (SuSE 9.2), 10GB (empty ext3), 12GB (empty ext3).

Questions/issues:

At one point I thought I saw a partitioning utility which listed free 
space but can't seem to get that kind of listing any more, is there a 
program or switch I'm missing?

This disk should have about 36.9GB of free space but when I try to 
create a new primary or extended partition nothing happens - no error 
messages but no new partition either.  What's wrong?
