I've finally got my first build up and running, but I hit a couple of snags when installing microsoft word and windows; nothing debilitating, but I'd like to format my SSD drive so I can neaten things up and get rid of a couple of small errors that keep coming up. My OS and some drivers are on the SSD, and its what the PC boots up from, but I do have a large HDD for basic storage. All I'd like to know is whether formatting my SSD will cause any irreversible problems given that the OS and more fundamental systems are stored in it. Bear in mind that I'll immediately be reinstalling the OS when I reboot.
