If this really will mark bad blocks, I could have real trouble (and I will
follow Ben Pfaffs advise to backup). I'm a bit confused: When I run e2fsck
-c on the drive again, will it find the bad blocks already found again?

I ran this command, and again I got timeouts. Then I ran the command a
second time, and it found (the same?) bad blocks. I think it were the same
because the sector numbers have been the same/similar?

I think the power supply is okay... I will run e2fsck -c again, will backup
and repartition the drive and will use it. And I will contact WD about the
warranty.

Thank you for your help,
