I hear this a lot. As a cynical, jaded old hacker from before the era
of long filenames on FAT, I still don't really believe it or trust it.
On Windows boxes, I have quite a few times rescued a dead machine, or
one that won't boot, by simply running `CHKDSK /F` on the C drive.
NTFS is very prone to minor cumulative disk corruption which the OS
does not notice or report.

I occasionally run an `fsck` on my Macs and my Linux boxes as a
precautionary measure, and it usually finds and fixes some small
problems. As it generally is, Linux is more resilient than Windows,
but not that much more. I've certainly had Linux boxes trash their own
hard disks, many times. It is in my experience a _particular_ problem
with Btrfs, exacerbated by the fact that the disk-repair tools for
Btrfs don't really work and you are advised not to use them.

:-o Really? Avast? I.e. a free version, on Windows?
