My netbook, an ASUS 1015PX, shipped with two harddrives. After switching to Ubuntu, the second drive isn't recognized by the OS or the BIOS. I've never formatted the second drive, so it's still set up for use by Windows.
I guess I don't care about the data on the drive, I'd just like to be able to use it again. It's probably also worth mentioning that I'm very new to any form of Linux, so I'm remarkably new to the Terminal.
