fdflush - force floppy disk drive to detect disk change
Fdflush is a band-aid for a common PC hardware
problem. Many PC floppy disk drives can't detect when the
disk has been changed. The symptom of this problem is that
when a disk is changed, the drive will continue to read
buffered data from the previous disk rather than new data
from the disk presently in the drive. Running fdflush
makes the system believe the disk-change switch has been
actuated, and the system discards the buffered blocks in
response to this information. If you have one of these
slightly-broken disk drives, you'll have to run
fdflush every time you change a disk.
The name of the floppy disk device, in the form /dev/fd1
. The default is /dev/fd0 .
They're in your hardware. Try swapping in another floppy
drive to see if this problem goes away.
/dev/fdN floppy disk device.
