NOTE:  1) These values may change depending on cartridge type and drive status. 

SPREV: If the SPREV bit is set, the device supports SPACE in the reverse direction. 

RO: If the RO bit is set, the device is operating in read-only mode. This bit does not 
reflect the state of the write protect flag on the cartridge which is indicated by the WP 
bit in the Mode Page Header. 

QFA: If the QFA bit is set, the device supports a two-partition format, which may be 
used for quick file access. 

EFMT: If the EFMT bit is set, the device supports ERASE command initiated 
formatting. 

CMPRS: If the CMPRS bit is set, the device supports data compression. 

ECC: If the ECC bit is set, the device performs error correction. 

DISCONNECT: If the DISCONNECT bit is set, the device can break up data 
transfers without the need to restrict transfer lengths to the Continuous Transfer 
Limit. 

EJECT: If the Eject bit is set, the device can mechanically unload the cartridge with 
the LOAD / UNLOAD command.
