1 1 Invalid selection or the drive is not completely plugged in. Also referred to as the “Un-Mated Case” option.
Note. If Enclosure Initiated ESI is supported in the backplane that the drive is plugged in to, the S2 and S1 values
reported may reflect attempts by the enclosure to start an EI ESI transfer. Several reads separated by at least a
second may better indicate what the value is for these lines that the drive uses to determine motor spinup
functionality. See Section 10.5 for more information on Enclosure Initiated ESI.
