(47)WRITE LOG EXT (X’3F’) [Optional command (Customize)]

•Description

This command writes data to the general-purpose log of a device. The general- purpose log includes the extended SMART comprehensive error log, extended self-test log, SMART selective self-test log, and other logs. However, some of these logs are read-only logs. The types of logs available depend on the customize operation. For information on the DRQ, INTRQ, and BSY protocols related to the transfer of data, see Section 5.4.1.
