thank you very much for your quick answer.

Of course I can run an additional extended self test on the disk but I am
almost sure that it will pass. I had done this after the first pendings
sectors showed up. The SEATOOLS for DOS (I have run all tests including
fill with zero) also did not report any problem.

This would be too bad. As far as I know, the "NS" and "AS" version (as far
as I remember the latter one is in the list of supported drives for
smartmon) differ only in that for the "NS" drive 24/24 operation is
allowed by the manufacturer whereas for the "AS" drive it is not. But,
perhaps there are other differences.
What worries me is that for one of the three disks these values are always
zero and do not change.
Just for information: I have "zeroed" the disk on saturday with the write
cache disabled (I have found that with "hdparm -W0" you can deactivate
it). So the write access should have gone directly to the disk. Result: no
reallocated sectors but the pending ones are still there.

Ok, I will do that but I am almost sure that it will pass.
Thanks again and best regards,
