Sorry if this is a stupid question you guys see often, didn't see it pop up on search... My C drive crashed, and I got a replacement drive. Installed windows xp on my new C, and my D can't be accessed in Windows. It claims it has to be formatted. I know hard drives can be swapped, why is it claiming that it has to be formatted all of a sudden? Both drives are FAT32, not NTFS, as I installed 98se then upgraded to xp with my original set up and this one. Also, I tried C as an NTFS and had no luck either. So my set up is the same with that, both FAT32, though I don't believe that makes a difference. Any ideas?
