Hello
I see that Speccy does not properly detect disk drives that are joined into storage spaces, see attached image.
I have three disk drives in a storage space and speccy detects them all as one entity, so I have four drives instead of six.
Me too (Windows Server 2016). Only one drive shows. Would be sweet to fix this but ultimately it is surely a low-usage use case.
Crystal Disk Info is able to show the all info on the underlying separate drives, by the way.
