I have a server with one hard disk array which is partitioned in to C and D. I've added three new hard drives and created a second array with those drives. Now, I would like to extend my D partition into this new array so that my D partition is much bigger. For some reason I keep getting an error in DISKPART saying the volume you have selected may not be extended." The D partition does not contain an OS and it also does not contain a page file. Both my C and D partitions show up as primary partitions. DISK 0 shows up as a basic desk. The new array I created shows up as DISK 1 and shows that it is also a BASIC disk. DISK 1 shows it's space as unallocated. I'm running server 2003 SP1. Any help would be appreciated.
