3.5-Inch Fibre Channel Solid State Drive 43
START/STOP UNIT (1Bh)
The Start/Stop Unit (1Bh) command is used to control the motor in a rotary device such as a hard
disk drive, and load or eject removable media such as tapes or CD-ROMs. It is frequently issued after
initial communication has been established between the initiator and target devices. However, the
command is irrelevant to an SSD. No action occurs and the command returns a “GOOD” status.

ECEIVE DIAGNOSTIC RESULTS (1Ch)
The RECEIVE DIAGNOSTIC RESULTS (1Ch) command will interrogate the results of a self-test that
was initiated by a previous SEND DIAGNOSTIC command. However, the SSD only supports Page
Codes 0x00 and 0x80. Page Code 0x80 is vendor-unique to STEC and is used to gather link error
statistics.
