Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have a problem. I had the "mount: wrong fs type, bad option, bad superblock on /dev/hdb1" problem and ended up loosing everything on both drives I had.
This error really needs to be fixed.
Anyway I have a WD3200BJ Western Digital 320 GB drive and it will not report anything larger than 305 GB capacity with 298 GB free. I have no partitions on this drive I am trying to get it running now. I also have a 250GB drive which is reporting find 239 total space available to partition. This problem started right after I got the error mentioned above.
Motherboard: A8N-SLI Premium
Hard Drive: Western Digital wd3200bj
System: Ubuntu 6.10
Also, I ran this hard drive for about a year with windows with no problems. It started when I put it in the new computer. The data is gone and there are no partitions on the drive so I can do what ever is needed to get this problem fixed.
This is the normal marketing gag of hard disk/DVD/storage media manufacturers. Your "missing" GB are simply not present physically. If you would have checked the drive size in Windows, it would have given you similar figures. Don't even try fixing it, you can't, it's normal your OS (Linux, Windows, whatever else) does display this values.
I understand that there is a difference between what is advertised and what is actual but a 22gb loss on a 320gb HD seemed a little much and I don't remember it being that big of a loss before my little error mentioned before.
Is there someone with this drive who can confirm this size for me?
AFAIK, you lost the additional 12GB because of the filesystem you selected. I have given up on ext3 precisely because of that. A 100GB partition would have only 94 or 95GB available; when I use XFS instead, it has 99.something available. Careful: I may be wrong - ext2 may be different from ext3 in this respect - but I guess someone else who is actually using ext2 could clear this up.
By default when an ext2/3 filesystem is created 5% is reserved for root use.
The output of the df command does not show this space. Reserved space is supposed to reduce fragmentation as well as allow root to login if the filesystem becomes full.
You can use tune2fs to reduce the amount of reserved space. If this filesystem is used just for data then you can safely set it to 0%
