Hello,

I have been using Knoppix for long time now. Normally I use it on my server machine with WinPartition method. Now I am trying to revive one of the old machines that I have. Knoppix works fine if booted off LiveCD. It sees my hard drives as well. But it can't mount any of the partitions. In fact when I do cfdisk or qtparted, it just gives me error saying failed to open device.

The problem disappears if I try cheatcode pci=off. But with this cheatcode, my network card (eth0) disappears too. Other than pci=off, no other cheatcode allows me to access any of the two hard drives I have. Is there any way to resolve this issue? Am I missing something here?

TIA.

Here is exact error message from cfdisk and some more info.

For cfdisk /dev/hda command, it shows error:
unknown partition table type.
Do you want to restart with new partition table?

I have tried answering yes to question above. In that case, it allows me to create new partitions etc but it fails while writing the changes. It just hangs in there. Any idea what could be wrong?
