[PATCH 5/6] Documentetion: cdrom: introduce CDS_DRIVE_ERROR

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



CDS_DRIVE_NOT_READY is used for the state in which CDROM is 'becoming
ready' (typically analyzing the disc) but also as the fallback when
nothing else applies. Introduce CDS_DRIVE_ERROR for the fallback case.

+Note: The IDE and SCSI cdroms have a status code 'drive becoming ready' which

+For other cdrom types this state is not reported by the hardware or not
