Drive

class Drive(*args, **kwargs)

GDrive represents a piece of hardware connected to the machine. It’s generally only created for removable hardware or hardware with removable media. For example, an optical disc drive, or a USB flash drive.

GDrive is a container class for Volume objects that stem from the same piece of media. As such, GDrive abstracts a drive with (or without) removable media and provides operations for querying whether media is available, determining whether media change is automatically detected and ejecting the media.

If the GDrive reports that media isn’t automatically detected, one can poll for media; typically one should not do this periodically as a poll for media operation is potentially expensive and may spin up the drive creating noise.

GDrive supports starting and stopping drives with authentication support for the former. This can be used to support a diverse set of use cases including connecting/disconnecting iSCSI devices, powering down external disk enclosures and starting/stopping multi-disk devices such as RAID devices. Note that the actual semantics and side-effects of starting/stopping a GDrive may vary according to implementation. To choose the correct verbs in e.g. a file manager, use get_start_stop_type.

For porting from GnomeVFS note that there is no equivalent of GDrive in that API.

Methods

class Drive

can_eject() → bool

eject(flags: MountUnmountFlags, cancellable: Cancellable | None = None, callback: Callable[[Object | None, AsyncResult, Any], None] | None = None, user_data: Any = None) → None

Asynchronously ejects a drive.

When the operation is finished, callback will be called. You can then call eject_finish() to obtain the result of the operation.

Deprecated since version 2.22: Use eject_with_operation() instead.

Parameters:

• flags – flags affecting the unmount if required for eject

• cancellable – optional Cancellable object, None to ignore.

• callback – a AsyncReadyCallback, or None.

• user_data – user data to pass to callback

eject_finish(result: AsyncResult) → bool

Finishes ejecting a drive.

Deprecated since version 2.22: Use eject_with_operation_finish() instead.

Parameters:

result – a AsyncResult.

eject_with_operation(flags: MountUnmountFlags, mount_operation: MountOperation | None = None, cancellable: Cancellable | None = None, callback: Callable[[Object | None, AsyncResult, Any], None] | None = None, user_data: Any = None) → None

Ejects a drive. This is an asynchronous operation, and is finished by calling eject_with_operation_finish() with the drive and AsyncResult data returned in the callback.

Added in version 2.22.

Parameters:

result – a AsyncResult.

enumerate_identifiers() → list[str]

Gets the kinds of identifiers that drive has. Use get_identifier() to obtain the identifiers themselves.
