Knoppix failed Install

[pheadxdll]

I've got knoppix to install once on the same computer, so this is very fustrating. When ever I try to install, I partiction the disks and I start the installsion. At about 60% or so the install keeps spitting out these errors like:

cp: reading 'usr/share/local/ru/LC_MESSAGES/popt.mo' : Input/output error

Serveral pages of the same errors (but different files), go by and the installsion is complete. I reboot and the boot gives errors and X windows doesn't load. I know its not the CD. I guess its the hard drive. I think I partitcioned them right though. I made a primary swap (512mb) and a primary ext3 (5.12gb) /. Thanks for any help, I really want to have knoppix installed over any other distro.

Can anybody diagnose the error for me or tell me what it means? That could help me find the problem. I really am desperate.
