The disk class, CD-ROM class, tape class and changer class drivers create FDOs of types FILE_DEVICE_DISK, FILE_DEVICE_CD_ROM, FILE_DEVICE_TAPE, and FILE_DEVICE_CHANGER respectively.įor information about designing PnP drivers, see the PnP Driver Design Guidelines. Storage port drivers create physical device objects (PDOs) of type FILE_DEVICE_MASS_STORAGE. Instead, the system-supplied tape class, changer class, or SCSI port driver handles these tasks on behalf of the miniclass/miniport, calling miniclass/miniport driver routines to gather the data needed to create the device object. IoAttachDeviceToDeviceStack attaches the new device object to the current top of the device stack.Ī tape miniclass, medium changer miniclass, or SCSI miniport driver is not required to create a device object and attach it to the device stack. Usb device malfunctioned and then try the host filesystem. The hard disk controller driver should typically be located under a category called disk drives or storage controllers.
#Mass storage device driver for windows how to#
Like any PnP driver, a storage class or storage filter driver adds itself to the tree in its AddDevice routine by creating a device object with IoCreateDevice and attaching it to the device stack with IoAttachDeviceToDeviceStack, using the pointer to the device object passed to the driver's AddDevice routine by the PnP manager at initialization. How to fix problem ejecting usb mass storage device on windows 10-problem ejecting usb mass storage device windows 10. The leaves of this tree are device objects for use by file systems and user-mode applications.

The root of this tree is a functional device object (FDO) for a storage adapter or for another driver stack integrated with the storage stack.
