When I put a floppy disk into my A drive and view the files through Explorer I see the contents OK.However, if I replace the floppy disk with another, the contents of the previous floppy are showing.I've used different file viewers,checked the drive in Device Manager (it says it is working properly) and run various hardware diagnostics and everything indicates that it is functioning correctly.
I am baffled and annoyed especially as none of my rescue disks work,most worryingly my Partition Magic disks.
Can anyone suggest a reason for this bizarre behaviour please?My OS is XP Pro if that helps.
Thanks for the tip but it will not work unfortunately.
The strange thing is that,even with the a second disk in the drive I can still open the contents of the first disk,up to a point.For example,the first disk contains a Zip file and a Read Me text file.I can read the text file and Winzip will attempt to open the Zip file but throws up an error message,obviously because another floppy drive is in the A drive.
I've been reading my PC hardware reference book and I've found the answer to my problem!Apparently it is known as the 'phantom drive'problem.When you change a disk in the floppy drive a signal is sent via pin 34 of the ribbon cable telling the PC that another disk has been inserted.
I found that the ribbon cable connection to the motherboard had come loose so that pin 34 was not connecting properly.I reseated the connector and everything works.
Thanks to pc moron and JonnyTub for their suggestions.
