I'm having problems repartitioning the HD in my T42.

I'm trying to use the partitioning tool that comes on the Ubuntu installer disc to resize my main partition from 55gb to 45gb. Everytime I try to do this through the guided partitioning tool, it says that it fails and that I have to do it manually. When I try to do it manually, the size of the partition does not change.

I've turned the security chip off, but that doesn't help. Do I need to use a different tool or what?

Any ideas?
