The information in this article applies to:
  • Microsoft Windows operating system versions 3.0, 3.0a, 3.1, 3.11
  • Microsoft Windows for Workgroups versions 3.1, 3.11

SUMMARY

If you use the MS-DOS device driver DRIVER.SYS to create a logical floppy drive, you may encounter problems accessing both the logical drive as well as the physical drive it represents from Microsoft Windows, especially from File Manager.

Some problems that you may be encountered are:

  • Drive letter(s) are not present in File Manager.
  • Drive letter(s) are present, but File Manager reports the drives do not exist when you attempt to access them.
  • MS-DOS error messages appear superimposed on the File Manager screen.
  • The system stops responding (hangs) when you access the drive(s).

MORE INFORMATION

The MS-DOS device driver DRIVER.SYS can be used to create a logical drive designator for a physical floppy disk drive. Drives configured in this manner are not supported in the Windows environment and can lead to erratic floppy drive and system behavior, particularly when the drives are accessed through File Manager.

Do not use DRIVER.SYS to configure physical or logical floppy drives if you plan to access those drives from the Windows environment.
