* [D] [Issue #27388] When unmounting a cloud drive with no volumes on it, and the system contains one or more volumes that
do not respond to IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS (e.g. emulated DVD drives that don't support it,
floppy drives, etc...), an error would be incorrectly generated on unmount.
Thanks for including the driver tracing logs. That captured the exact problem.
