Why is the drive unable to write data to a floppy disk?
The floppy disk drive cannot write data to a disk if it is inserted into the drive
improperly. See “Inserting and removing floppy disks” for instructions on how to
insert the disk properly.
If the disk is inserted properly and you are still unable to write data to it, the disk
may be write-protected. You can either use a floppy disk that is not write-
protected or disable the write-protect feature.
