Question : Problem: unable to add new volume to existing RAID 5 array...Help

Hello Everyone

Ok I'v read through everything on this site regarding this problem, but I still seem to need assistance.
Quick overview
sbs 2003 sp1
xeon 3.0 ghz, 1 gig ram
system on C drive 120 gig's
Raid array E drive 300gig's (160 x 2, and parity 160)
Hardware raid (3ware 9500s) SATA controller
added 2 new drives to take the raid array from 3 drives to a 5 drive array.
plus 1 hot spare

controller migrated the new drives and see's them all including the hot spare
however drive management saw only a unallocated new 300 gig's
did a quick format on the unallocated part, now it's sees a new volume of 300 gig's
tired diskpart, now it see's the new volume (it didn't before the quick format)
but I'm unable to extend it as part of the E drive (Raid 5 array)
did read about the fxextend.exe. however this server is part of a non profit org. and getting $300 usd just for the call is not an easy situation.
please advise how to extend this into the existing array ASAP

The reason that you can not extend the volume to the new space is that you have already allocated the space to a new volume. You will need to delete the new volume that you have created and do the following.

To extend a basic volume
Open Command Prompt.
Type:
diskpart

At the DISKPART prompt, type:
list volume

Make note of the number of the basic volume you want to extend.

At the DISKPART prompt, type:
select volume n

Selects the basic volume, n, you want to extend into contiguous, empty space on the same disk.

At the DISKPART prompt, type:
extend [size=n]

Extends the selected volume by size=n megabytes (MB).

The amount of space, in megabytes (MB), to add to the current partition. If you do not specify a size, the disk is extended to take up all of the next contiguous unallocated space.
