I recently bought a 15" MacBook Pro on eBay. It's essentially brand new, and works fine (besides having the whine and the heat issues). However, I noticed when I first started it up that there were two drives mounted on my desktop (see pictures below). I tried going into Disk Utility to erase it (it appears to be a Boot Camp partition that was never removed when the previous owner restored the computer), but it would not let me erase it. I was able to unmount, it, but the next time I restarted the computer, it was there again on my desktop. I don't have ownership permission of the partion: is there any way to delete it? Thank you!
