Can I partition a set of disks using this into additional logical volumes under Windows XP? I am finding information that says you can't parttion a RAID array.

You can partition RAID arrays just fine. They would be useless if you couldn't

The problem is with drivers though. If you are going to use the DOS version of PM, then you need DOS drivers for your RAID array. If you have a crappy SATA fakeraid, then there are no such drivers and you can only partition from within Windows.

I want to partition through Windows and Dell said it can;t be done. It arrived with a 250gb drive already parititoned into a Dell Utility parittion (FAT), an unallocated one 31 mb, C drive, 59MB extended, D: Back up, CP/M Concurrent DOS, CTOS. I have no idea why this is this way. I just want three more logical drives to be added.

You can use Partition Magic (or some other Windows partition utility) no problem. Maybe the Dell person meant software RAID?

I partioned my raid drive without any issues
