The REPORT DENSITY SUPPORT command provides information regarding the supported densities for the
logical unit be sent to application client.
MEDIA : The MEDIA bit of ZERO indicates that the drive will return density support data block for densities
supported by the logical unit for any supported media. The data returned by the drive will be static if the MEDIA
bit is ZERO. The MEDIA bit of ONE indicates that the drive will return density support data block for densities
supported by the mounted medium. If the MEDIA bit is ONE and the logical unit is not in the ready state, a CHECK
CONDITION status will be returned. The sense key will be set to NOT READY.
The Allocation Length field specifies the maximum number of bytes that the drive may return.
