LED1	Green	Fast Flash	Drive could not write to tape correctly - cleaning required
LED1	Green	Off	Cartridge not loaded
LED2	Amber	On	Drive is reading or writing to the tape
LED2	Amber	Fast Flash	A hardware fault occurred or moisture detected on tape
LED2	Amber	Off	Drive is not reading or writing to the tape
LED3	Green	On	A data compression or decompression operation is in progress on the current cartridge
LED3	Green	Off	A data compression or decompression operation is not in progress on the current cartridge
LED4	Green	On	A write-protected cartridge is currently loaded
