Has anyone else run into this problem. We have a machine which had hardware Promise RAID in use with RedHat 9. When we installed Fedora Core 4 on the machine, since dmraid didn't recognize the Promise hardware RAID partitions, we disabled the Promise hardware RAID in the BIOS and installed FC4 with software RAID-1 partitions. The FC4 install CD recognizes these partitions without complaint. However the FC5 install CD complains that the partition map on the drives are corrupted. My guess is that dmraid is seeing some residual tattooing on the drives and not using the software RAID. Is there some way to disable dmraid on this system during the installation? I would rather not have to do a low level format just to eliminate the residual tattooing. Jack
