Supported Log Pages Log Page (00h)
Page 00h indicates the log pages used by the drive. To determine the size of each
page and of each parameter in the page, the individual page must be requested.
Page 00h is unique in that the log parameters returned do not contain log parameter
headers. All other pages return a log parameter header for each log parameter.
Page 00h is valid only for the LOG SENSE command. When page 00h is requested,
the four-byte page header is returned followed by the list of log pages—one byte for
each log page. The list of log pages is returned in ascending order.
