This page is supported for compatibility of device driver.
Recommendation: A device driver should not be used this page, because if device driver uses of this page and it is not able to keep compatibility for logically of media (No guarantee).
"Transfer Rate" defines "kbits/sec".
"Number of Heads, Sectors per Track and Number of Cylinders" define logical value. It does not show physical numbers. No guarantee for logical compatibility of media when device driver or application is used this value.
"Data Bytes per Sectors" defines Block Length (200h or 800h).
"Motor off Delay" defines time for spinning down operation. X'FF' is to does not stop motor forever.
"Medium Rotation Rate" defines revolutions per minute.
