You still have much more chances to avoid writing a bad byte w/ ECC
than with regular RAM, though.

That's why I like this FS, which is now more usable with powerful
chipsets/CPUs.

Not that I know of (but I always make a looong destructive test
before use, either on regular partitions and swaps).

This isn't a good idea, perfs are much degraded using that.
