I have two external Samsung X5 2TB Thunderbolt 3 SSDs. Both of them work fine after I reformat them. But when I delete files (and empty the recycle bin), the space on them does not increase. In order to get space back, I need to empty it, reformat, then rebuild up files on it.
So far I have tried the following:
- Enabling TRIM. It's enabled, does nothing.
- Showing hidden files/folders to make sure nothing is hiding on the drive. There's nothing there, trash on the volume is empty, etc.
- I've tried running "First Aid" in Disk Utility. It runs fine and finishes but it doesn't fix the problem.
What could be causing this? I am running MacOS Monterey on an M1 Max laptop.
