Any reason why LO cannot show all desktop drives when opening and saving files?

Can you add some informations on your linux-distribution and desktop?

I remember to read about mounted network-shares not accessible by LibreOffice. Reason seemed to be a “direct mount” of the KDE-desktop, where the shares eere visible in Konqueror and KDE-applikations, but not everywhere. (KIO was the keyword, if I’m remembering right).

Wich type of “desktop drives” are you missing?

thanks for reply.
sys info noted above. the drives are ‘hard drives’ and ‘sd cards’.

From another site, I see the drives must be added manually, by clicking a green button displayed in the file-save dialogue. However, the drives have system labels, not user labels.

So, how to create pseudonyms for the drive labels?
