I have been meddeling with KNOPPIX for a few days now, and decided that I would like to create a persistant home. WHen it asks where I would like to install the home, it doesn't give me any HDA options... only SDA. When I tray to install it on SDA or SDB it says

The KNOPPIX configuration could NOT be saved: /dev/sda: Input/output
error
mount: you must specify the filesystem type
I've tryed going into the commpand prompt and typing "df -h" to look at the hard drives or something, but it doesn't show any.

Any help with this would be much appreciated.
