The only Space codes that are supported are 001b (Filemarks) and 011b (End of Data on Current Partition). For Space Filemarks, negative count (2s compliment) indicates Space Filemarks Reverse.
The DSC bit is reset (0) after this command is accepted and is set (1) when the command is completed and the drive is ready. REQUEST SENSE can then be used to verify successful command completion.
