Upgraded on Pentium 100 machine that lists hard drive 0 (854MB) and hard drive 1 (811 MB). Before was showing as C: and D: . Formatted C: . Now shows only C: at 854 MB. Tried Partition Manager - No help. I've created a monster of a mess on a machine that doesn't belong to me. Please tell me how to fix!! :-/ Also, in the process I lost the internet connection. Control panel shows only "Make new connection" icon. Wired to Road Runner.
