UDISKS(7)			    udisks			     UDISKS(7)

NAME
       udisks - Storage Management

DESCRIPTION
       udisks provides an interface to enumerate storage devices and perform
       operations on them. Any application can access the
       org.freedesktop.UDisks service on the system message bus. Some
       operations (such as formatting disks etc.) is restricted using polkit.

DEVICE INFORMATION
       On Linux, udisks relies on recent versions of udev(7) and the kernel.
       Influential device properties in the udev database include:

       UDISKS_PRESENTATION_HIDE
	   If set to 1 this is a hint to presentation level software that the
	   device should not be shown to the user.

       UDISKS_PRESENTATION_NOPOLICY
	   If set to 1 this is a hint to presentation level software that the
	   device should not be automounted or autoassembled (for e.g.
	   components of a multi-disk device).

       UDISKS_DISABLE_POLLING
	   If set to 1 this will disable the polling of drives for media
	   changes, for devices which do not send out media notifications by
	   themselves (this mostly affects CD drives). Some CD drives cause
	   bad effects such as very high CPU usage when being polled.

       UDISKS_PRESENTATION_NAME
	   The name to user for the device when presenting it to the user.

       UDISKS_PRESENTATION_ICON_NAME
	   The icon to use when presenting the device to the user. If set, the
	   name must follow the freedesktop.org icon theme specification.

       The ID_DRIVE_* properties are used to describe what kind of physical
       media can be used in a device. These are typically set on the main
       block device (e.g.  /dev/sdb) and more than one these properties can be
       set if the device supports multiple kinds of media.

       ID_DRIVE_EJECTABLE
	   Whether the media in the drive is physically ejectable. Only set
	   this to 1 (or 0) if the drive truly uses (or doesn't) ejectable
	   media. In particular, it is not necessary to set this for e.g. iPod
	   or Kindle devices where it is necessary to send a command via
	   eject(1) since the desktop user session will offer this option for
	   removable devices regardless of whether they are ejectable. If this
	   property is not set, a heuristic will be used to determine if the
	   media is ejectable (drives using optical, Zip or Jaz media are
	   considered ejectable).

       ID_DRIVE_DETACHABLE
	   Whether the device is detachable. It is only meaningful to set this
	   to 0 (to avoid marking a device as detachable) since the code for
	   detaching the device is part of udisks itself. If this property is
	   not set, a heuristic will be used to determine if the drive is
	   detachable (currently only devices connected through USB are
	   detachable).

       ID_DRIVE_CAN_SPINDOWN
	   Whether the device can spin down. It is only meaningful to set this
	   to 0 (to avoid marking a device as being capable of spinning down)
	   since the code for spinning down the device is part of udisks
	   itself. If this property is not set, a heuristic will be used to
	   determine if the drive can spin down (currently only ATA devices,
	   including those USB devices with a SAT layer) can be spun down).

       ID_DRIVE_FLASH
	   The device is compatible with flash.

       ID_DRIVE_FLASH_CF
	   The device is compatible with Compact Flash.

       ID_DRIVE_FLASH_MS
	   The device is compatible with Memory Stick.

       ID_DRIVE_FLASH_SM
	   The device is compatible with SmartMedia.

       ID_DRIVE_FLASH_SD
	   The device is compatible with SecureDigital.

       ID_DRIVE_FLASH_SDHC
	   The device is compatible with High-Capicity SecureDigital.

       ID_DRIVE_FLASH_MMC
	   The device is compatible with MultiMediaCard.

       ID_DRIVE_FLOPPY
	   The device is compatible with floppy disk.

       ID_DRIVE_FLOPPY_ZIP
	   The device is compatible with Zip.

       ID_DRIVE_FLOPPY_JAZ
	   The device is compatible with Jaz.

       The ID_DRIVE_MEDIA_* properties describe the current media in a device.
       As with the ID_DRIVE_* properties, these properties are typically set
       on the main block device (e.g.  /dev/sdb). Typically only one of these
       properties are set.

       ID_DRIVE_MEDIA_FLASH
	   The physical media currently inserted into the device is flash.

       ID_DRIVE_MEDIA_FLASH_CF
	   The physical media currently inserted into the device is Compact
	   Flash.

       ID_DRIVE_MEDIA_FLASH_MS
	   The physical media currently inserted into the device is Memory
	   Stick.

       ID_DRIVE_MEDIA_FLASH_SM
	   The physical media currently inserted into the device is
	   SmartMedia.

       ID_DRIVE_MEDIA_FLASH_SD
	   The physical media currently inserted into the device is
	   SecureDigital.

       ID_DRIVE_MEDIA_FLASH_SDHC
	   The physical media currently inserted into the device is
	   High-Capicity SecureDigital.

       ID_DRIVE_MEDIA_FLASH_MMC
	   The physical media currently inserted into the device is
	   MultiMediaCard.

       ID_DRIVE_MEDIA_FLOPPY
	   The physical media currently inserted into the device is floppy
	   disk.

       ID_DRIVE_MEDIA_FLOPPY_ZIP
	   The physical media currently inserted into the device is Zip.

       ID_DRIVE_MEDIA_FLOPPY_JAZ
	   The physical media currently inserted into the device is Jaz.
