Hi, my drives went missing after I restarted my computer. I use Windows 2000 SP4. My problem is my three drives (M, N, and O Drive) went completely missing. When I go to my Device Manager, it does not show any other drive except my L drive. Luckily, my L Drive is still intact; however, my M, N, and O Drive isn't shown anywhere at all. It is as if my drives are completely wiped out. I have even went to my Partition Magic to take a look. Partition Magic only shows me L Drive and 131GB unallocated space. My L Drive is only 29.3 GB. The fact is that my hard drive is 250GB. My drives M, N, and O are gone, and I don't know what to do to get them back. This all happened after I restarted my computer when I finished the defragment for my C Drive. It all happened so unexpectedly. If I had known what this would happen, I would have made lots of backups, but now, I can no longer do that. I have tried searching around in the internet and tried the solutions but with no luck. I had many important files on it, and some of them mean a whole world to me. What can I do to get my three drives back?
