Cannot Access Floppy Drive When Backup Program Is Running (139474)
The information in this article applies to:
This article was previously published under Q139474 SUMMARY
When you are running Microsoft Backup (or another 32-bit Windows-based
backup program) you may receive the following error message if you try to
access a floppy disk drive from My Computer or Windows Explorer:
<drive>:\ is not accessible
You may also receive the following error message:
device is not ready
These error messages can occur even if there is a formatted disk in the
drive.
In addition, if you are performing a backup, restore, or compare operation,
the operation may be canceled if you try to access the floppy disk drive
from a command prompt.
MORE INFORMATION
This behavior occurs when you have a tape drive connected to the same
floppy disk drive controller as the floppy disk drive you are trying to
access.
When a 32-bit Windows-based program is accessing one of the drives
connected to the floppy disk drive controller, all other drives on the
controller are unavailable. When you attempt to access a floppy disk drive
from a command prompt, any active backup, restore, or compare operation is
canceled because Windows 95 cannot prevent floppy disk drive access from
occurring when the drive is accessed from a command prompt.
