AVF: Address Valid Flag. When the AVF is 1, the Sense Information (bytes 3-6) 
contains valid information. 

FM: When the Filemark bit is set to 1, a Filemark has been encountered during a 
read operation. 

EOM: The End-of-Media bit, when set to 1, indicates the tape has reached the 
Logical Early Warning Point. 

ILI: The Illegal Length Indicator, when set to 1, indicates that the length of the block 
read from the media does not match the block length specified by the READ or 
COPY command, or the length specified by MODE SELECT. 

Sense Key: Defines the type of failure associated with the current Check Condition 
(02h Status). The Sense Keys are defined in the following table. 

Sense Information: When the AVF bit is 1, the Sense Information bytes represent 
the difference between the Transfer Length requested by the command and the 
actual number of blocks or bytes transferred (i.e., the residue). 

Additional Sense Length: The Additional Sense Length specifies the number of 
bytes to follow this byte. For all commands except the COPY command, this field is 
38h.
