I had two drives go out on my server and I need to restore my server from my NTBackup that I have. I have read through some of the questions and post but I had a question about can I change the drive sizes. I was thinking about replacing all 8 drives on my Dell PowerEdge 2900 with bigger but same size drives and then doing the restore. Can you do this? Also do you have to reinstall the OS before you can do the restore or can you do it from the Utility that I have been reading about.
