Declaration

#define kIOPropertyRigidDiskGeometryKey

Discussion

This key is used to define a dictionary containing rigid disk geometry information.

Requirement: Optional. If a device publishes this dictionary, it must publish all key/value pairs which are deemed Mandatory.

Example:

 
 
<dict>
   <key>Device Characteristics</key>
   <dict>
   	<key>Vendor Name</key>
   	<string>Apple</string>
   	<key>Product Name</key>
   	<string>iPod</string>
   	<key>Product Revision Level</key>
   	<string>1.0</string>
   	<key>Rigid Disk Geometry</key>
   	<dict>
   		<key>Sector Count per Track</key>
   		<integer>12345</integer>
   		<key>Head Count</key>
   		<integer>12</integer>
   		<key>Cylinder Count</key>
   		<integer>12345</integer>
   		<key>Bytes per Physical Sector</key>
   		<integer>512</integer>
   	</dict>
   </dict>
