       diskd - disk daemon; wait for disk to be inserted

Note

       This  manpage  has  been  automatically  generated  from  fdutils's texinfo documentation.
       However, this process is only approximative, and some  items,  such  as  cross-references,
       footnotes  and  indices are lost in this translation process.  Indeed, these items have no
       appropriate representation in the manpage format.  Moreover, only the  items  specific  to
       each  command  have  been  translated,  and the general information about fdutils has been
       dropped in the manpage version.  Thus I strongly advise you to use  the  original  texinfo
       doc.

       *      To generate a printable copy from the texinfo doc, run the following commands:

                     ./configure; make dvi; dvips fdutils.dvi

       *      To generate a HTML copy,  run:

                     ./configure; make html

              A pre-made HTML can be found at: `http://www.tux.org/pub/knaff/fdutils'

       *      To generate an info copy (browsable using emacs' info mode), run:

                     ./configure; make info

       The  texinfo  doc  looks most pretty when printed or as HTML.  Indeed, in the info version
       certain examples are difficult to read due to the quoting conventions used in info.

Description

       The diskd command has the following syntax:

          diskd [-d drive] [-i interval] [-e command]

       Diskd waits for a disk to be inserted into a given drive, and  then  either  executes  the
       command  or exits. This program can be used to automatically mount a disk as soon as it is
       inserted.

Warning

       This program works by switching the motor on for a very short interval, and  then  seeking
       to  track  -1.  This  might  damage hardware in the long run. Amigas, which also use these
       techniques, are known for having problems with their disk drives  no  longer  spinning  up
       properly after a few month of usage.

Options

       -d drive
              Selects  the drive to observe for disk insertion. By default, drive 0 (/dev/fd0) is
              observed.

       -i interval
              Selects the polling interval. The interval is given in tenths of  seconds.  Default
              is 10 (one second).

       -e command
              Gives  the  command  to be executed when a disk is inserted. If no command is given
              the program simply exits. Typically, the command mounts the disk. It can be a shell
              scripts which probes for several filesystems and disk geometries until it succeeds.

Bugs

       *      Automatic  unmounting  cannot  yet  be handled. It is indeed not enough to scan for
              disk removal, because when the disk is removed, it is already too late: There might
              be  some  buffers needing flushing.  However, the fdmountd program allows automatic
              unmounting by using the SYNC mount options, which switches off write buffering (see
              section  fdmount).

       *      The  drive  motor  is  running  all  the time, and on some computers, the drive led
              flickers at each time the drive is polled.
