Just the law of probability, if you have say a 1 in 1000 chance of a
failure with one disk then you have a 2 in 1000 (or 1 in 500) chance
with 2 disks.

Noooo...it would still be 1 in 1000 for each disk. If one crashed and
took the other with, then the odds would change to 1 in 500, but since
one crashing does not mean the other will crash at the same time, it
remains 1 in 1000 per disk.

Yes, but that still comes out at 1:500 for =the system=, which is what
the OP was probably talking about.

I have never had a HD failure and I almost always use two drives.
Maybe I'm just lucky but none of my friends have called me with a HD
failure issue. Well, maybe one but I cannot remember for sure.

You snipped/missed the point. Regardless of the extent of
the failure, a bad drive is something which has to be dealt
with and is annoying.

That said, there are indeed some failure modes which can
damage all drives (like a bad power surge or a badly
overvolting PSU or a dangerously overheating case).

I've been unlucky, perhaps. I've had 5 hard drives go bad
in the last three years.

Nope. I got your point. That remark was made by Seabat.

But this was my comment. ;) I would say bad luck for sure. Who do you
use? I have used Seagate, WD and Maxtor without issue.
