What exactly is it "trashing" because I've been doing this for 20 years and have never lost a file. To be clear, I never put anything on a USB flash stick I'm not ready to lose in the first place, and I could just re-transfer the file or reformat it if necessary.

I even do it with bootable USB drives, windows installation, etc. Never had a problem. Not saying it's incorrect, I'm just really curious what information is being lost or corrupted when doing this, and if it really matters for the vast majority of situations, because my personal experience tells me no.

edit: I guess it's a write cache thing, I do vaguely remember this being a concern in the past, but I never had issues with just pulling the drive regardless.
