The Finder confuses with wildly inaccurate figures for available space

in any case, due to the ”sudden death”-problem of these Sanddisk SSDs, maybe i is time to consider copying important data to a different product.
yeah, i just got a samsung shield t7 and have that as a backup
the sandisk drives are still faster so im using them for now
Just an update because I think I got it sorted.
This thread here put me on the trail:
I did a few things, so Im not sure exactly which one fully did the trick.
I used DiskDaisy to figure out that there was a large amount of space being taken up by "hidden space". I then turned off snapshots in carbon copy cloner, deleted the snapshots (which didnt add up to the missing space), and then logged into recovery mode to run disk utility first aid. Got 800gb back.
Hope this helps someone else if the issue comes up

Yeah, super annoying
Here's how to get rid of them https://daisydiskapp.com/img/guide/ccc_deleting_snapshots.png

Snapshots are great. I use CCC and not Timemachine to manage backups and snapshots. I will typically set a backup volume to store one snapshot each day and auto-delete snapshots older than a month or two. I will also use CCC to manually delete snapshots if I need to free up space.
The CCC backup of my main system drive is also bootable, which lets me boot from it, tell CCC to restore the main drive to a state recorded by a snapshot from last night or last month. And because I'm not booted from the main drive, CCC will restore only modified files, which is done in seconds rather than much longer if I use recovery/diskutilities to restore because it rewrites the whole disk. So a restore to any time in the last two months is done in a couple of minutes.
Added: Much like in Timemachine, you can also double-click on a snapshot in CCC, find a file or folder from whenever, have it show in Finder, and drag it to the desktop to restore it.
