The EXT3 disk partitions created by FC2 have problems.

Both "Partition Magic 8.0" and "Acronis Disk Director 9.0" flag the
EXT3 partitions as having errors or unsupported and refuse to resize them.

EXT3 partitions built by RedHat 9 appear normal and can be resized.
Not so with partitions created by FC2.

Build a brand new FC2 system from release ISO's.
Attempt to resize any of the EXT3 partitions with "Partition Magic
8.0" or "Acronis Disk Director 9.0".

The partitions should be resizeable and should not show errors.
