You were wrong, wptski was right.
The free version allows you to mount backups, any BU. ("grey out" because not "show partitions". Рaragon can mount only partitions, and regardless of whether the content of the backup - whole disks or folders and files - all can be mount as partitions.)

Nevertheless, I think that the full version will not disappoint you. Especially since this HDM - not just tools for the backups, but a multi processor for a variety of operations on the hard disk (and other storages).
