Implemented Interfaces

UDisksLinuxDriveAta implements GDBusInterface and UDisksDriveAta.

Description

This type provides an implementation of the UDisksDriveAta interface on Linux.

Functions

udisks_linux_drive_ata_new ()

UDisksDriveAta *
udisks_linux_drive_ata_new (void);

Creates a new UDisksLinuxDriveAta instance.

Returns

A new UDisksLinuxDriveAta. Free with g_object_unref().

udisks_linux_drive_ata_update ()

gboolean
udisks_linux_drive_ata_update (UDisksLinuxDriveAta *drive,
                               UDisksLinuxDriveObject *object);

Updates the interface.

Parameters

drive	A UDisksLinuxDriveAta.
object	The enclosing UDisksLinuxDriveObject instance.

Returns

TRUE if configuration has changed, FALSE otherwise.

udisks_linux_drive_ata_refresh_smart_sync ()

gboolean
udisks_linux_drive_ata_refresh_smart_sync
                               (UDisksLinuxDriveAta *drive,
                                gboolean nowakeup,
                                const gchar *simulate_path,
                                GCancellable *cancellable,
                                GError **error);

Synchronously refreshes ATA S.M.A.R.T. data on drive using one of the physical drives associated with it. The calling thread is blocked until the data has been obtained.

If nowake is TRUE and the disk is in a sleep state this fails with UDISKS_ERROR_WOULD_WAKEUP.

This may only be called if drive has been associated with a UDisksLinuxDriveObject instance.

This method may be called from any thread.

Parameters

drive	The UDisksLinuxDriveAta to refresh.
nowakeup	If `TRUE`, will not wake up the disk if asleep.
simulate_path	If not `NULL`, the path of a file with a libatasmart blob to use.
cancellable	A GCancellable or `NULL`.
error	Return location for error.

Returns

TRUE if the operation succeeded, FALSE if error is set.

udisks_linux_drive_ata_smart_selftest_sync ()

gboolean
udisks_linux_drive_ata_smart_selftest_sync
                               (UDisksLinuxDriveAta *drive,
                                const gchar *type,
                                GCancellable *cancellable,
                                GError **error);

Starts (or aborts) a SMART self-test on drive . Valid values for type includes 'short', 'extended', 'conveyance' and 'abort'.

The calling thread is blocked while sending the command to the drive but will return immediately after the drive acknowledges the command.

Parameters

drive	A UDisksLinuxDriveAta.
type	The type of selftest to run.
cancellable	A GCancellable that can be used to cancel the operation or `NULL`.	[allow-none]
error	Return location for error or `NULL`.

Returns

TRUE if the operation succeed, FALSE if error is set.

udisks_linux_drive_ata_apply_configuration ()

void
udisks_linux_drive_ata_apply_configuration
                               (UDisksLinuxDriveAta *drive,
                                UDisksLinuxDevice *device,
                                GVariant *configuration);

Spawns a thread to apply configuration to drive , if any. Does not wait for the thread to terminate.

Parameters

drive	A UDisksLinuxDriveAta.
device	A UDisksLinuxDevice
configuration	The configuration to apply.

udisks_linux_drive_ata_secure_erase_sync ()

gboolean
udisks_linux_drive_ata_secure_erase_sync
                               (UDisksLinuxDriveAta *drive,
                                uid_t caller_uid,
                                gboolean enhanced,
                                GError **error);

Performs an ATA Secure Erase operation. Blocks the calling thread until the operation completes.

This operation may take a very long time (hours) to complete.

Parameters

drive	A UDisksLinuxDriveAta.
caller_uid	The unix user if of the caller requesting the operation.
enhanced	`TRUE` to use the enhanced version of the ATA secure erase command.
error	Return location for error or `NULL`.

Returns

TRUE if the operation succeeded, FALSE if error is set.

udisks_linux_drive_ata_get_pm_state ()

gboolean
udisks_linux_drive_ata_get_pm_state (UDisksLinuxDriveAta *drive,
                                     GError **error,
                                     guchar *pm_state);

Get the current power mode state.

The format of pm_state is the result obtained from sending the ATA command CHECK POWER MODE to the drive.

Known values include:

0x00: Device is in PM2: Standby state.
0x40: Device is in the PM0: Active state, the NV Cache power mode is enabled, and the spindle is spun down or spinning down.
0x41: Device is in the PM0: Active state, the NV Cache power mode is enabled, and the spindle is spun up or spinning up.
0x80: Device is in PM1: Idle state.
0xff: Device is in the PM0: Active state or PM1: Idle State.

Typically user interfaces will report "Drive is spun down" if pm_state is 0x00 and "Drive is spun up" otherwise.

Parameters

drive	A UDisksLinuxDriveAta.
error	Return location for error.
pm_state	Return location for the current power state value.

Returns

TRUE if the operation succeeded, FALSE if error is set.

UDISKS_LINUX_DRIVE_ATA_IS_AWAKE()

#define         UDISKS_LINUX_DRIVE_ATA_IS_AWAKE(pm_state) (pm_state >= 0x41)

Decodes the power state value as returned by udisks_linux_drive_ata_get_pm_state.

Parameters

pm_state

The power state value.

Returns

TRUE when the drive is awake, FALSE when sleeping.
