NAME
       fdflush - force floppy disk drive to detect disk change

SYNOPSIS
       fdflush [device]

DESCRIPTION
       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-bro-
       ken disk drives, you'll have to run fdflush every time you
       change a disk.

OPTIONS
       device The  name  of  the  floppy disk device, in the form
              /dev/fd1 .  The default is /dev/fd0 .

BUGS
       They're in your hardware.  Try swapping in another  floppy
       drive to see if this problem goes away.

FILES
       /dev/fdN  floppy disk device.
