There's a limit to how many primary partitions you can make...<BR /><BR />Try running the ADU from the Smartstart CD on the array, in case there's a hardware issue.

(4x9Gb and 4x18Gb.) <BR /> <BR />The 5302 has been setup with array 'A' as RAID1 across 2 9Gb disks, array 'B' as RAID1 across 2 9Gb disks and array 'C' as RAID 0+1 across 4 18Gb disks. <BR /> <BR />Using Disk Manager in Windows 2000, arrays 'A' and 'B' can be partitioned and formatted and given drive letters, but array 'C' is detected as 'Unknown', has a red warning icon and can't be partioned. <BR /> <BR />Any ideas? Thanks.
