This is almost a little embarrassing to ask, but I just can not figure this one out myself really. I'm trying to find out where the disks of my machine are used and if they are actually used at all.
If I check my available disks in my debian, I can find 4 of them. This seems correct. There should be a 50GB one, a 120GB one and two 1.5TB disks. Here by uuid and by path.

But when I check my mount, I can not find all of those disks.

If I check the disk usage, I can not identify any of the big 1.5TB disks

But I'm actually already lost here, I think I'm looking a the wrong thing. Can anyone point me at what I have to look for if I simply want to know how and where my hard drives are used in the debian OS? It's just that if the two 1.5TB are actually not used at all, I could take them out and use it for something else...
Thank you very much in advance for helping.

alright, now I'm totally confused... there are two volume groups called "temp_vslide" but they are not mounted anywhere?
