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.

BTW, I use Samsung 1TB Raid Class drives, and have been replacing my Seagates with Samsungs as they die. Not that Seagate is bad - these drives are all at least 2 years + old. Seagate's RMA department wasn't that professional to me, so I've decided not to buy anymore of their products
You need to enable the sector based hard disk and not the cylinder based hdd use, when starting fdisk (append -u) or inside fdisk (press u). That is currently all you have to do.
Newer fdisk versions (which are currently not in slackware-13 or slackware-current) use that mode per default or the user is allowed to diable the old dos-compat mode with -c which includes the sector based use too.
All I know about these drives is from non-Linux sites (eg here), but my impression was that there is a jumper on the back of the drive that you can set to put the drive back into a compatibility mode.
Now, it would seem that a consequence of doing this would be that you lose the extra capacity and performance benefits, if any, by doing this, but it sounds as if it should work, even if it would not be ideal.
BTW, I got the impression that it was only a matter of time before other drive manufacturers start to use these formats...any idea whether that is true?
I just upgraded my desktop with 2 1.5TB WD "Green" drives and noticed a similar performance hit. Everything in X seemed to freeze sporadically for about 10 seconds. It did this when I was copying things to the HD as well as when the system was idle.
After reading this thread, I re-installed Slackware partitioning the drives with the fdisk -u command. It seemed like the easiest solution, so I felt I'd try it out.
I don't understand how it displaying the size of the drive in sectors instead of cylinders would make any difference. It does, however, seem to have made the system more responsive. It does slow down every once in a while but nothing like it was doing (almost completely unresponsive). I'm not sure if this is due to the hard drives, or that I'm using a Dell Dimension 8400 P4 system. It only has 1GB of RAM currently, I'm thinking of upgrading to 2 or 4GB, perhaps that would help.
I am turning my desktop into a seedbox and am copying over 385GB of data to the new drive. I have read in another forum someone saying their Green drive had severely slow write speeds. I don't notice anything currently, but can anyone give me the process of doing a speed test once this transfer is through?
I think these "green" drives probably have some nasty firmware that tries to save energy in a stupid way ... just a theory, but why else would they call it "green". You won't find be buying anything "green".
