Medalist 1080sl SCSI Product Manual, August 1995
The sense data applies to the previous command on which a check
condition status was returned. This sense data is saved for the initiator
until:
The initiator requests the sense data using the Request Sense com-
mand, or
Another command is received from the initiator that issued the original
command that caused the check condition status.
If any of the following fatal errors occur during a Request Sense com-
mand, the drive sends a check condition status, and the sense data may
be invalid.
The drive receives a nonzero reserved bit in the CDB.
An unrecovered parity error occurs on the data bus.
A malfunction prevents return of sense data.
If any other error occurs during the Request Sense command, the drive
returns sense data with a good status.

Byte 4 The allocation length specifies the maximum number of bytes
the initiator has allocated for returned sense data. The drive
returns the number of bytes specified by the allocation length up
to 22 bytes. If the allocation length is set to zero, no sense data
is returned. This is not an error.
