What function do i use for resetting a deviceobject which is a disk file system driver ?
instead using IoDeleteDevice and IoCreateDevice ???
Why ??
I want use one call IoCreateDevice (and a other IoCreateDevice for VPB disk) and using IoDeleteDevice only when i unload my driver.

Reseting = request to a windows kernel for re checking drive for recheck (IOCTL_VERIFY … IRP_MJ_READ … IRP_MN_MOUNT_VOLUME)

You need to and dismount the volume, see FSCTL_DISMOUNT_VOLUME. Once the
volume is dismounted the I/O Manager will trigger mount processing again on
the next open.
