How To Fix fdflush: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu fdflush is provided by fdflush package.

fdflush is:

fdflush is a band-aid for floppy (or other) drives with bad disk-change sensing. fdflush makes the system believe the disk-change switch has been triggered forcing the system to discard the buffered data.

If you have one of these slightly-broken disk drives, you’ll have to run fdflush every time you change a disk.

fdflush is useful for computers which might be sleeping when you change floppies or other removable media.

The command “floppycontrol -f” does the same thing, but the fdutils package is significantly larger; it only uses the floppy-specific flush ioctl.

The command “blockdev –flushbufs” only uses the generic flush ioctl.

To fix this problem, we can install more using the command below.

sudo apt-get -y install fdflush

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install fdflush.

sudo apt -y install fdflush

Or if you have aptitude installed you can use the following command.

sudo aptitude install fdflush
