I can't get my floppy drive to work. It will sound like it is working but it won't read the files on the floppy. the hour glass shows until it says that "a" is not accessible. I added another parallel card last night but did nothing to connections or memory. Everything else is fine. What happened all of a sudden? I did see that when attempting to run the maintenance wizard it said that there was not enough memory....i'm running 512mb. All programs were closed.
