I have a Dell Inspiron 5150 laptop with a spare HDD. I'm trying to install Knoppix 4.0 on the spare drive (it can be safely wiped as everything of importance is on the other drive; this one is old). QTParted will not allow me to format or even partition the drive; the error message I get is "does not support opening ntfs" or similar. Any ideas? I have been told that Dell does something strange with their restore partition that may be affecting any partitioning attempts.
