I have had no problems in the past ever using windows 95,98,ME and XP. But I just installed the upgrade to windows xp pro and now my floppy isn't being detected. I can boot from floppy still, the system device manager it shows up being there, just not anywhere else in win xp pro.
I will try removing from device manager today and rebooting and see if that helps and also I will try seeing if it hid itself by getting tweakui today. I tried re-installing win xp pro upgrade and it didn't help. If i removed xp pro I know it will detect again because I never had that problem.
I will see if the other suggestions help me, and if all else fails I can try a new floppy because its very old though I will try that last.
