Byte 1 If the PF (Page Format) bit is set to 0 and the self test bit is
1, the drive performs the buffer RAM diagnostics, which is
the default self-test. If the default self- test is requested, the
parameter list length is 0 and no data is transferred. If the
self-test passes successfully, the command terminates with
a good status. If the self-test fails, the command terminates
with a check condition status and the sense key is hardware
error.
