How to increase volume size in RAID 5 array

I have a Dell PowerEdge 2850 running Win2K Server.  It has three drives in a RAID 5 array.  It has two volumes on it, called "C:" and "D:".  I added a fourth drive which has increased the size of the array, but the size of each volume is still the same.  Is there any way to increase the size of each volume without destroying the data on it?

Run diskpart.exe from the Windows 2000 Resource kit: It's an online expansion tool - but make sure that you have a good backup first. Better safe than sorry.

You can then select the partition and select expand. And that's it. Easy!
I don't think diskpart works on the system drive meyersd.

Yes - you're quite right.

Missed that. <slap on the wrist for me>

RTFQ :-)

I'm not sure if Partition Magic will do what's needed for the C: drive....
W2K server needs PowerQuest/Symantec Volume Manager.
PM will not install on a server class product.
