I have a client with a server 2003 box. Best I can tell it's not set in a raid. I know the server has two physical drives. I also see two drives listed in the explorer. Under drive manager it just shows (disk0) and lists the size of each drive next to it. I am not 100% sure its not in a raid because I cant reboot the server. My question is I need to swap these drives out with two larger drives 500gig. I don't know what the best way to do this is and keep all data intact. I would like to use some sort of clone or mirror software but I'm not sure whats the best way to go about this. Any help would be great. Attached is an image of the drive manager.
