Knoppix 4.0.2 CD won't work correctly on my computer
I recently got a knoppix 4.0.2 disk at school and played around with it a little bit there (it works). However, when I go to my home PCs, I get numerous error messages and in the end the screen goes black and it never boots.
1) With the CD in I turn the PC on and the splash screen (with boot comes up, I hit enter.
2) I get these error messages. I tried taking a picture of them with my dig. camera, though it didn't turn out too great.

Something about buffer read i/o error on device hdc. Being completely new to Linux I can't say I understand any of it. I was hoping you guys could help me out here and get this thing to work on my computers.
3) The process gets to autoconfiguring devices and hangs with a full bar for a few minutes.
4) The screen goes black and nothing else ever happens.
This is almost the same on both of my computers, and I thought it might be the CD but it worked at school and it looks like it's in good shape (no scratches, etc). Any help you can offer would be great.
Specs on the computer I'm trying it on: Hewlett Packard (groan, I know, tell me about it), AMD 2800, Radeon X800XL video card, 2x 512 Corsair value RAM. If you need anything else let me know.
[edit] Sorry about the double post, I clicked submit and the page never loaded so I thought it wasn't working and hit it again.

Cloop I/O errors usually indicate that the downloaded ISO was in some way corrupt, or the CDR media itself is bad, or CDR was burned too fast, or the CDROM drive is too sensitive to small burning errors. See "17 Q: My PC will boot off of the burned disc. It is strange since it loads but then stalls or it loads but is giving me I/O errors. What's going on?". Anyone who download & burns Knoppix CDs should first read the Downloading FAQ where we discuss how to download the ISO image without corruption and how to properly burn a CD that will work on practically all CDROM drives.

Sounds like you have a bad CDROM drive, or it needs cleaning.

Hey, I figured out that it was the CD. Why it worked at school and not at home I don't know, but I downloaded and burned my own Knoppix copy this time and it works like a charm (as well as it can on my 128 memory anyway ) Thanks guys!

Very likely a sloppy high speed burn, as Underscore pointed you towards in the reference to the Downloading FAQ. Such disks tend to work and not work on different systems just as you saw. It is very hard for us to convince people thay have a bad disk since they think that "I know it is a good disc because it worked on ...." is more meaningful than anything we can tell them. We have to let them learn for themselves as you did.

Yeah, well I can understand now why it was burned at a high speed because the guy who gave it to me made 24 (!) copies in one day of it for this one club I'm in at school. Not sure why burning at a higher speed messes things up but it's all good now (reminds me of a certain Sony game console I have....).
Thanks for helping a newb like me out!
