Run smartctl -t long, and see what the LBA of the errors are (smartctl
-a when finished, and look at the error log) - it may be that it is
outside of the used space (e.g. right at the end of the drive - I've
seen this in the past) if this is the case, you can just dd over it.

I will do that maybe after the repair-action is through ...

Could you tell me in detail what you mean by "dd over it" ? Write zeros
there or what ...?

If the test completes without error then the unreadable sector is either
not user-addressable, or doesn't really exist, in which case I'd ignore
it (or perhaps a security-erase will get the drive back into a sensible
state).  Some of the earlier firmwares for the ST3250310NS were a little
buggy in my experience, so you might want to look at upgrading it
(latest Seagate non-OEM firmware is SN06), which can be done with hdparm.

You know I really hesitate with such low-level-stuff as the server is
far away and I won't be able to just boot from a live-cd or something
... so I am very cautious with my steps.

Thanks so far, Stefan
