Dobrý den,
zde je chyba v nápovědě: https://www.rar.cz/faq.php?title=napoveda%3Aprepinac-sv-vytvaret-zavisle-di ly-solid-archivu
-sv-
Create dependent solid volumes
Disables to reset solid statistics between volumes.
It slightly increases compression, but significantly reduces
chances to extract a part of data if one of several solid
volumes in a volume set was lost or damaged.
Ignored if used when creating a non-volume archive.
