Thanks for the quick response!

I have an 80GB western digital HD. I do not have any 3rd party programs loaded. I did not partition the drive and did a standard XP Pro install. My confusion starts with the gpart information. I don't understand the information provided on partition 1 and 2. When doing a sudo cfsidk /dev/hda, it lists only partition 1 and 80GB. Don't know if this helps you any?

I did not do a gpart -w since the information seemed incorrect from the gpart -v. When running testdisk, I get the following error:
knoppix@Knoppix:~$ testdisk
testdisk: error while loading shared libraries: libntfs.so.9: cannot open shared object file: No such file or directory

The problem started when I had an unsuccessful bootup in XP. After shutdown, when I re-started I began receiving the disk read error message. I used the windows XP CD with the attempt of recovery. The only suggestion from windows was to re-format the partition. I have a Dell Dimension 8250 desktop.

I have a question:
When doing any commands like mount, gpart or fdisk,... should I execute against /dev/hda or /dev/hda1? When executing against /dev/hda, I get a permission denied error. The gpart information in my first post was executed against /dev/hda1. The sudo cfdisk command was successful against /dev/hda. Sorry for the very ignorant question but I'm trying to learn this.

My desktop in Knoppix displays hda1 only. When attempting to mount, I get errors. Thanks again for your help. I greatly appreciate it!
