I have Windows Home Server setup with 2 250 GB hard disk. Recently one of my drive died and now it is left undiscovered from the BIOS. The problem is not that I don't want to replace the drive, I can do so but I have some questions with WHS setup. If I reinstall WHS, do I need to format both the disk? If yes then what about my data, it will be lost completely. How will I recover them then?
