I had XFS eat some data once. I somehow got it into a state where it wouldn't mount and wouldn't fsck. Luckily for me it was "just" my backup disk, so after a week of fighting with it I just gave up and reformatted (as ext4) and didn't end up losing much. Was eye opening though. I'd rather have a slightly less featureful fs that I have a chance of recovering…

I've had really bad experiences with fat32 and xfat... back in the day it was pretty common to lose data due to hard drive or filesystem bullshit.

In any case, I was a technology journo at the time this happened, and I covered this story, but I don't recall encountering a lot of technical discussion... it seemed to be mostly "ew this guy murdered his wife". Which is entirely deserved. (If a little unfair to the creative work)

I wasn't much of a programmer yet so maybe I wasn't looking at the right discussions.

ReiserFS and BTRFS always seemed like the two big "performance over reliability" Linux file systems.
