macrofByteToBlockShift

macrofDeviceIsShared

The fDeviceIsShared is used to indicate whether this device exists on a Physical Interconnect that allows multiple initiators to access it. This is used mainly by the power management code to not send power state related START_STOP_UNIT commands to the device. The fDeviceIsShared value is also used to prevent power state commands from being sent to manual eject device since these devices behave better when allowed to manage their own power.
#define fDeviceIsShared fIOSCSIBlockCommandsDeviceReserved->fDeviceIsShared

macrofMediumBlockCount64

The fMediumBlockCount64 provides support for 64 bit LBAs and replaces fMediumBlockCount which only supports 32 bits. This value should not be directly accessed and instead the member routine ReportMediumTotalBlockCount() should be used to retrieve it and the member routine SetMediumCharacteristics() should be used to set it.
#define fMediumBlockCount64 fIOSCSIBlockCommandsDeviceReserved->fMediumBlockCount64

macrofRequiresEjectWithStartStopUnit
