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 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.

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.
