DiskDruid problem

[Mursalin]

i have partitioned my HDD with pqmagic. and i have installed redhat 5.2 some
sonth before. now, i got redhat 6.0. the installation program gives an error
(corrupted partition) when i attempt to run diskdruuid/fdisk.

redhat 5.2 runs fine. i can mount other partions. pqmagic does not report
anything wrong.

can anyone help me please?
