      Diskette drive maintenance

      Diskette drive maintenance

      Note: Some of these steps may not apply to your computer.

      This following information is provided to assist you in obtaining optimal performance from your diskette drive.

      To gain the best long-term reliability from a diskette drive, you should utilize only high quality media, keep the system in a clean environment, and keep any foreign objects out of the diskette drive.

      The following is a checklist of processes to implement to prevent premature diskette drive failure.

      • Check all diskettes for physical damage and ensure the diskette shutter moves freely prior to inserting into the diskette drive.
      • Use the diskette drive on a regular basis. Frequent use cleans the recording head surfaces of dust or fiber particles that may adhere to the heads via minute static electrical charges. Frequent use also minimizes the risk of contaminants damaging the diskette, which could result in read/write errors.
      • If the drive has not been used for an extended period, test the drive first with an expendable diskette, and verify that it can be read from, and written to prior to inserting a critical data diskette.

        Attention: When using a diskette drive cleaning kit, be sure to follow the manufacturer's directions carefully. When using kits with isopropyl alcohol, be careful not to use excess amounts of the solution. Excess solution may accumulate on the drive's heads, resulting in the degradation of the diskette's magnetic recording surface, and possibly transfer to the next diskette inserted in the drive. This can cause residue to be left on the heads of the drive which can compound the issue.

      1. Check to see if the diskette you are trying to use works in another computer's diskette drive. If the diskette does not work properly in either computer, replace the diskette. However, if the diskette works OK in one drive, but not the other, then cleaning the drive may be required. Follow the cleaning kit manufacturer's directions. Also refer to the maintenance information above.
      2. Verify the drive is recognized in the Devices section of the System Configuration Utility.
      3. Verify the drive is shown in the Startup Sequence section of the System Configuration Utility as the first startup device.
      4. Verify the computer will boot from a known good DOS bootable diskette.
      5. Verify the machine will read and write to the diskette after booting from the DOS diskette.
      6. Check if the drive works with the computer cover removed.
      7. Verify the diskette drive is recognized by the operating system in Safe Mode.

        1. Restart the system. When you see the message "Please select the operating system to start", press F8.
        2. Use the arrow keys to highlight the appropriate safe mode option, and then press Enter.

          In Safe Mode you have access to only basic files and drivers (mouse, monitor, keyboard, mass storage, base video, default system services, and no network connections). You can choose the Safe Mode with Networking option, which loads all of the above files and drivers and the essential services and drivers to start networking, or you can choose the Safe Mode with Command Prompt option, which is exactly the same as safe mode except that a command prompt is started instead of the graphical user interface. You can also choose Last Known Good Configuration, which starts your computer using the registry information that was saved at the last shutdown.
      8. Reseat or swap cabling and power connections if possible.
      9. Check for cut cabling. Some systems employ tray mounting methods which may cut cables when improperly installed.
      10. Reposition the computer to make it horizontal if it is a desktop model in a vertical position.
      11. Check if the drive works with the drive removed from the chassis. Refer to your computer's Hardware Maintenance Manual for directions on how to remove the diskette drive.
      12. Check if the drive and cable works in another computer.
      13. Check if another drive and cable works in this computer.
