itself. In systems that support disconnection, the drive disconnects while
executing this command.

Byte 1 If the PF (Page Format) bit is set to 0 and the SelfTest bit
is set to 1, the drive performs the buffer RAM diagnostics,
which is the default self-test. If the default self-test is re-
quested, the parameter list length is 0 and no data is
transferred. If the self-test passes successfully, the com-
mand 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.
If the PF bit is set to 1, SelfTest bit is 0, device off line
(DevOfL) and unit off line (UnitOfL) are ignored and a
diagnostic page is sent as the parameter list. The supported
pages are the
Supported Pages (00
H
) page and the Trans-
late Address (40
H
) page. The parameter length is 4 (04
H
)
bytes for page 00
H
and 14 (0E
H
) bytes for page 40
H
.
The DevOfL bit is not supported and must be 0 if
SelfTest
bit =1.
The UnitOfL bit is not supported and must be 0 if
SelfTest
bit =1.
Bytes 3–4 The parameter list length must be 0 if SelfTest bit =1.
