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.

       UDISKS_AUTOMOUNT_HINT
           A variable to influence whether a device should be automounted. Possible values
           include "always" (to hint that a device should always be automounted) and "never" (to
           hint that a device should never be automounted). Note that this is only a hint - the
           auto-mounter might not honor it.

       UDISKS_SYSTEM_INTERNAL
           If set, this will override the usual bus type based detection of whether a device is
           considered "system internal". "0" means "removable" (i. e. eligible for automounting,
           and normal users can mount), any other value means "system internal" (i. e. no
           automounting, and only administrators can mount).

       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-Capacity 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-Capacity 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.
