You can create a filesystem on a floppy just as you would on a hard
|
|
drive partition. For example,
|
|
<P><TT> # <em>mke2fs /dev/fd0 1440</em>
|
|
<P></TT>
|
|
creates a filesystem on the floppy in <tt>/dev/fd0</tt>. The size of the
|
|
filesystem must correspond to the size of the floppy. High-density
|
|
3.5" disks are 1.44 megabytes, or 1440 blocks, in size. High-density
|
|
5.25" disks are 1200 blocks.
|
|
<P>

|
|
In order to access the floppy, you must <b>mount</b> the filesystem
|
|
contained on it. The command
|
|
<P><TT> # <em>mount -t ext2 /dev/fd0 /mnt</em>
|
|
<P></TT>
|
|
will mount the floppy in <tt>/dev/fd0</tt> on the directory <tt>/mnt</tt>.
|
|
Now, all of the files on the floppy will appear under <tt>/mnt</tt>
|
|
on your drive. The ``<tt>-t ext2</tt>'' specifies an ext2fs filesystem type.
|
|
If you created another type of filesystem on the floppy, you'll
|
|
need to specify its type to the <tt>mount</tt> command.
|
|
<P>
|
|
<A NAME=4720> </A>
|
|
The ``mount point'' (the directory where you're mounting the filesystem)
|
|
needs to exist when you use the <tt>mount</tt> command. If it doesn't exist,
|
|
simply create it with <tt>mkdir</tt>.
|
|
<P>
|
|
See Section <A HREF="node184.html#secmanagefs">4.8</A> for more information on filesystems, mounting,
|
|
and mount points.

<IMG ALIGN=BOTTOM ALT="(WARN)" SRC="bdt.gif">Note that any I/O to the floppy is buffered just as hard
|
|
disk I/O is.
|
|
If you change data on the floppy, you may not see the drive light come
|
|
on until the kernel flushes its I/O buffers. It's important that you
|
|
not remove a floppy before you unmount it; this can be done with the
|
|
command
|
|
<P><TT> # <em>umount /dev/fd0</em>
|
|
<P></TT>
|
|
Do not simply switch floppies as you would on an MS-DOS system; whenever
|
|
you change floppies, <tt>umount</tt> the first one and <tt>mount</tt> the
|
|
next.
