[Evert Vorster <evorster@gmail.com>]

I thought this would go to the list automatically.

Here it is now.

I lost a btrfs not long ago, and this is the reason I am on this list.
Lucky for me, I have more than one backup of everything. Most people
that use computers do not. Also, they unplug USB disks without
unmounting, etc....

I don't think the signboards are big enough.

Most people assume that there is some way of fixing a broken file
system, and finding out the btrfs does not have one usually is quite
surprising and just a little too late.

I was under the impression that with atomic writes it's impossible to
mess up a file system?
