I recently saved some documents to a floppy but now whenever I do something like open a web page or any saved documents a noise comes from the A Drive as if I am trying to use it for something. I have shutdown and restarted but it still happens.
You can stop the noise quite quickly by leaving a floppy in the drive. Then you will find the normal explorer window will open pointing to the a:\ drive. Shift the pointer to somewhere else and open a document or program or something. Once explorer then closes, it should then remember the other drive not a:\ next time
