2. Write-access must be turned ON for each drive you wish to write to. It is turned OFF by default.
If you're using KDE, right click on the hd icon and select "change read-write status" (it's something similar, I may be slightly wrong in the wording as I'm not on a knoppix system now).

From a command line it's:

mount /dev/hda1 /mnt/hda1 -oremount,rw

Note: replace hda1 in both places with the proper partition device number.
