Actually the partitions were made when I installed Windows on the harddrive, so
they are the wrong format. I didn't even think of that. Thanks for the link...I'm
going to read it right after I reply here.
The reason this harddrive has partitions is because of that BIOS 32gig max, actually.
I installed this harddrive on an old computer where I used it for a while, until I got
this new computer. The harddrive itself is 80gb but the first and second partitions are
both 30gb. This is all that my Linux OS sees. But actually, there's something strange.
I had Windows XP on the second partition of my harddrive and when I start up it
brings up Windows in the OS choices menu, so the BIOS itself is recognizing the
other partitions (unless maybe there's a boot record on the first partition or something)
but Linux isn't. I'm not using Redhat though, it's the OS that came with the computer,
CPU Builders Linux. I figure I'll switch to a different version of Linux and probably
install some version of Windows on another partition or something eventually, but
for now I'd like to get stuff set up so that I'll still have some idea of what's going on
when I do switch to another version. I'm also somewhat hesitant to start formatting
and installing new OSes because that's how I killed my previous computer, and
it's why I have this new one. Thanks again, though. I'll check out both of those
articles and see if they help.

EDIT: Aha!
Code:
fdisk -l
Disk /dev/hda: 40.0 GB, 40020664320 bytes
255 heads, 63 sectors/track, 4865 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 4799 38547936 83 Linux
/dev/hda2 4800 4864 522112+ 82 Linux swap
Disk /dev/hdb: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hdb1 * 1 3824 30716248+ c Win95 FAT32 (LBA)
/dev/hdb2 3825 9729 47431912+ f Win95 Ext'd (LBA)
/dev/hdb5 3825 7648 30716248+ b Win95 FAT32
/dev/hdb6 7649 9729 16715601 b Win95 FAT32
So it does recognize that the other partitions exist...
