Hello, I am running windows 2003 server. I currently have 3 72gb disks, raid 5 configuration. We are running out of space on this server. I have  available drive bay. Is it possible to just add another 72gb hard drive to this array to gain more space WITHOUT reformatting/reconfiguring server ?
I just want to be able to add more space and not have to redo that whole server. Any takes ?

Kinda.

It depends if the RAID controller and what drive you want to expand.  Some RAID controllers support dynamically expanding the array.  Doing so only expands the HARDWARE array, it does not expand the logical drives within Windows.  For that you have to use DISKPART command line utility.  HOWEVER, DISKPART cannot expand the c: drive, only non system drives can be expanded.

So even if my raid controller could do this, your saying I would still have to extend that drive in windows ?

Yes.  The RAID controller (as far as I've ever seen) cannot extend the logical Windows partitions.  It MAY be possible to use windows based RAID controller management software could do that, but I've never seen any that could.

Would help if you posted the RAID controller your using and which drive(s) you want to expand.  We MAY be able to provide further information.
