I have a hard drive that was fdisked to ~30gb back when I had windows 98/me/2000. Not sure which it was.
Anyway, it used to be ~60GB in size, and due to some issue, it was would only be recognised as ~30GB - and it was fdisk-ed down.
Now, running windows xp, and fdisk no longer exists, and I can't seem to find a way to ressurect the fdisk-ed drive. (It's connected via USB).
