I'm trying to install Knoppix to my HD via the 'knoppix-installer.' When i create an Extended 29.85 GB partition, and format it in ext3 as a logical drive, the installer says: 'Error: File System has an incompatible feature enabled.' What's wrong? For the swap partition, QTParted would NOT let me make it Extended, so i was forced to keep it as a 100 MB Primary partition. I had to type 'IGNORE_CHECK=1 knoppix-installer' in order to go ahead and install Knoppix, anyway. However, it said it formatted the partition as 'reiserfs', but i want it as ext3, why did this happen? The reason i want to make the partition Extended in the first place is because i already have MacOS X installed on this drive.It is on a primary partition and set active. What can i do now?

Thanks in advance.
