Extend my RAID5 primary partition

[Guest sbs newbie]

Sorry for the double post. I also posted in the SBS NG and should have

posted here first. I have a DELL Power Edge 4600 server running W2K3 SP1

The server has an integrated dual channel Perc 3Di RAID controller. On one

is my OS configured RAID 1 (2 x

18GB) SCSI drives. On the second channel is my Data RAID 5 (6 X 73GB - 1 hot

spare) SCSI drives. On my Data array I have 1 single primary partition. The

new

drive I added is part of the RAID5 set and of course it shows as

"Unallocated". I want to extend my primary partition to include this new

drive. Can this be done using Partition Magic or can anyone suggest a better

tool and procedure of doing this.thanks in avance.
