The Flexible disk page is only supported for compatibility of device drivers.
Device drivers should not use this page to guarantee the logical compatibility of
media.
The unit of Transfer Rate is kbps.
Number of Heads, Sectors per Track, and Number of Cylinders define logical
values, and do not indicate physical values. If a device driver or application uses
these values, logical compatibility of media is not guaranteed.
Data Bytes per Sector defines block length (200h or 800h).
Motor off Delay defines the duration after which the motor is instructed to stop.
FFh indicates that the motor is not instructed to stop.
Medium Rotation Rate defines revolutions per minute (rpm).
