-/*++
-
-Routine Description:
-
- This routine updates the capacity of the disk as recorded in the device extension.
- It also completes the IRP given with STATUS_VERIFY_REQUIRED. This routine is called
- when a media change has occurred and it is necessary to determine the capacity of the
- new media prior to the next access.
-
-Arguments:
-
- DeviceExtension - the device to update
- IrpToComplete - the request that needs to be completed when done.
-
-Return Value:
-
- NTSTATUS
