NAME

DeviceKit-disks - Disk Management  

DESCRIPTION

DeviceKit-disks provides an interface to enumerate block devices and perform operations on them. Any application can access the org.freedesktop.DeviceKit.Disks service on the system message bus. Some operations (such as formatting disks etc.) is restricted using PolicyKit.  

DEVICE INFORMATION

On Linux, DeviceKit-disks relies on recent versions of udev(7) and the kernel. Influential device properties in the udev database include:

DKD_PRESENTATION_HIDE

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

DKD_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).

DKD_PRESENTATION_NAME

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

DKD_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 DeviceKit-disks 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 DeviceKit-disks 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.
