Creating Linux and Swap partitions on a blank drive

[UnderScore]

Isn't better swapping with /dev/hda1 since it's the faster

Yes if you use swap space it should have better performance. But for maintenace or data forensics purposes it is necessary to disable swap acess.
*Try this only on a spare HD *
Partition & format a spare HD as I suggested in the post above.
Then reboot Knoppix normally. Then attempt to add, remove, resize partitions while the swap partition is enabled. It may be successful or it could fail. The write/resize processes will attempt to change the sectors on the HD where the swap is currently active. It could work but each process will be stepping on each other sort of like 2 people trying to go through a door-way at the same time.
