To be fair, there are still some ECC systems. Unfortunately most
of the home-use Intel boxes aren't. My own home-use box isn't and
(now 6+ years ago) I had bad RAM in it that produced single-bit
errors in an inode block that led to panics that led to me finding
the single-bit errors, but I don't know if there are some damaged
files.
I keep thinking I'll replace it with a new box that does have ECC,
but haven't gotten around to it yet. I see some consumer-priced
AMD CPUs have at least theoretical ECC support but I haven't found
anything that says the ECC actually works, and have seen a few
articles that hint that it doesn't. iX sells NAS boxes that do
have ECC, though.
