Name
       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 represen-
       tation  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 ad-
       vise you to use the original texinfo doc.

       *      To generate a printable copy from the texinfo doc, run the  fol-
              lowing 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 ei-
       ther executes the command or exits. This program can be used  to  auto-
       matically 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  com-
              mand 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 re-
              moved, it is already too late: There might be some buffers need-
              ing  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.
