The DEVICE_SEEK_PENALTY_DESCRIPTOR structure is used in conjunction with the IOCTL_STORAGE_QUERY_PROPERTY request to retrieve the seek penalty descriptor data for a device.
VersionContains the size of the structure DEVICE_SEEK_PENALTY_DESCRIPTOR. The value of this member will change as members are added to the structure.
SizeSpecifies the total size of the descriptor, in bytes.
IncursSeekPenaltySpecifies whether the device incurs a seek penalty.
Storage class drivers issue a device-control request with the I/O control code IOCTL_STORAGE_QUERY_PROPERTY to retrieve this structure, which contains seek penalty information for data transfer operations. The structure can be retrieved either from the device object for the bus or from an FDO, which forwards the request to the underlying bus.
Used in conjunction with the IOCTL_STORAGE_QUERY_PROPERTY request to retrieve the seek penalty descriptor data for a device.
VersionContains the size of this structure, in bytes. The value of this member will change as members are added to the structure.
SizeSpecifies the total size of the data returned, in bytes. This may include data that follows this structure.
IncursSeekPenaltySpecifies whether the device incurs a seek penalty.
