I've tried a number of different ways of tracking down what's using the space on my SSD drive. I apologize in advance as I don't totally understand Linux and filesystems.
I have three drives. The SSD is 120GB and intended to have the operating system and programs. Some is partitioned to swap, so of the 112GB on the main partition only has 20G available.
here is df -h output
$ df -h Filesystem Size Used Avail Use% Mounted on udev 3.9G 0 3.9G 0% /dev tmpfs 788M 82M 706M 11% /run /dev/sda1 103G 78G 20G 81% / tmpfs 3.9G 28M 3.9G 1% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup /dev/sdb1 3.6T 327G 3.1T 10% /media/Media /dev/sdc1 3.7T 2.5T 1.2T 68% /media/Data tmpfs 788M 72K 788M 1% /run/user/1000 /dev/mapper/veracrypt7 2.0T 451G 1.5T 24% /media/veracrypt7
I can't begin to find what's using the 92GB. I tried several
du commands mentioned in other posts, and the 2 largest directories are only 4GB (
/usr) and 2GB (
/var). Nothing else even comes close in size. I tried
ncdu and it also did not find anything of substantial size on that drive.
My other 2 drives are 4TB each and house my media / backups / Plex / Nextcloud. That's all I use this system for.

The Disk Usage Analyzer application gives me similar results - "/" is 7.9GB,
/usr is 4.2GB,
/var is 1.8GB, and it gets smaller from there. It just doesn't add up, which is frustrating. It does say
error opening directory '/etc/ssl/private':Permission denied. As for hibernation, I have no idea. I've never enabled it. Is there a way to check? RAM is 8GB
If anyone can help me find what's using the mystery 86GB I would appreciate it. When answering please remember that I know next to nothing!
