Hello,
Thank you all for your answers.
First I would like to understand
better what's happening. According to what I read, there are no block in the
disk itself, they refer to the word sector. Then, the OS, here OpenBSD format
it with a block size.
So from a physical point of view I have faulty sectors
on my disk right ?
I bought this disk about a year ago. And ok, I write in a
few files (~1000 rrd files) every minute all year long. I'm surprise that you
guys ask me to throw the disk away because a few blocks out of thousands are
faulty.
Smartmontools doesn't complain about my disk

Once a disk sprouts an error, it cannot be trusted. This has always
been true, but in an era of multi hundred G disks, any tiny particles
floating around in a disk resembles large rocks pummeling the
insides of a disk. You MAY be OK and have just a few bad sectors
but the uneasy question is, will you get more, how many, and where?
Not to mention all the other failures that can happen.
I have had disks with bad sectors that I "mapped" out by never
touching files where the bad spots were, and had the disk live for
five years. I've also seen a case where a friend showed me a
disk that had one bad sector on it, and tens of thousands the
next day.
You are dancing on a volcano. I hope it doesn't erupt on you.
Make backups. Rsync is a good friend. Really.
