ValhallaSystems,

I am seriously "reaching" here, so take pity on me if this doesn't solve, or work, but, its my best I can offer on the issue...

I think your partition is already mounted, by Knoppix, when you booted - my guess...

Go to a Konsole window, and try the following "view" command ( for Disk Free):

Code:
cuddles@Morpheus:~$ df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda5              4806904   2946124   1616596  65% /
/dev/hda6             34218604  15114240  17366136  47% /home
cuddles@Morpheus:~$
What devices are mounted in your output? I am going to take a "stab" at the fact your hard drive partition will show up in the output, and it was probably "mounted" by Knoppix on boot, and is defaulted to read-only. If you get a /dev/hdX# in the output of df, try a root Konsole, and do a umount /dev/hdX# - on the device. Then try your installer again, and see what happens. ( like I said, this is a stab at it )

Another thought, this is about as simple as I can think of, you are running the installer in a "root" window, right? If you are running this as a "normal" user, do a su to get root priviledges, and then re-run the installer...

I also had problems with the installer in v3.4 - my success was to actually run the mkfs.ext3 manually ( I think, it has been a few weeks of doing my install )

A few things, that I can come up with, from the top of my Geekette head...

Hopefully, this helps,
Ms. Cuddles
