Thanks for the answer.
However, I did not have the chance to test it, because I had the very 
bad idea to reboot.
I tried to fsck and had lots of :
ad2: FAILURE - READ_DMA status=51 <READY, DSC, ERROR> error=40 
<UNCORRECTABLE> LBA=xxxxxxx

So the system was marked as dirty, and I could not boot.
I just could backup datas and reinstall all.
making a newfs on the damaged slice made the errors disppear.
I suppose it's normal.
But I cannot understand why fsck was unable to correct it, because it 
asked me if I wanted to correct, but told me then that it could not 
write on this sector.
That's weird .
