Q. If I put floppy disc in the A: drive, it works Ok. If I then change the floppy to any other one, it continues to see the first one...
A. The Floppy Disk Drive Phantom Directory Problem
Symptoms: When a floppy disk is inserted into floppy disk drive and the directory is displayed, the directory of the floppy that was previously in the drive is displayed.
Caution: Writing to the second floppy will damage the data on it. The write also writes part or all of the previous floppy's FAT and directory sections.
Background: Pressing the eject button to remove the previous floppy normally sends a Disk Change (DC) signal to the floppy drive controller. If the signal does not get to the controller or the controller is defective, the operating system will not flush the floppy cache'.
Temporary fix: Press Ctrl-C in DOS right after inserting the floppy. That should flush the
cache'.
Troubleshooting:
1. Reseat the floppy cable at both ends.
2. Replace the floppy cable. To verify, Check pin 34 continuity.
3. Make sure the pins labeled DC on the floppy drive printed circuit board are jumpered.
4. Dirty (or bad) disk change sensor or LED. Remove floppy, gently open door, and blow dust out of the drive. Carefully clean through floppy door with cotton swab and isopropyl (rubbing) alcohol (use sparingly; keep away from heads).
5. Bad floppy drive printed circuit board. Replace drive.
6. Bad floppy disk controller (part of the motherboard now-a-days). Find a controller card (good luck!), replace the motherboard, or go without.
