files wont write to drives

[SomeProgr]

Im using Knoppix 3.4 c't edition, and am having problems. I need to write files to another drive, (doesnt matter hda 3 or 4) but it wont let me. When I try to copy a file to that drive, I get the error, "Could not write to /........ (Cancel, Skip, Auto Skip)" Any idea of why its doing this?

You have to make sure the other drives are mounted use kwickdisk found in your programs under sytems then under more programs if i remember correct. In linux drives have to be mounted kwickdisk is a easy fast mount tool
