Yep, it's a Seagate.

All four are Seagate:

sda, sdb: ST3250310NS  (should have ERC as far as I found online)
sdc, sdd: ST3250621NS  (still don't know if they have ERC)

I now decided to run that check-action on all three arrays.

So far it looks good. All three arrays re-synced OK, without any drive
failing. Good :-)

Still no reallocated sectors on all four drives.

"Current_Pending_Sector" and "Offline_Uncorrectable" on /dev/sdb still
at the old value of "13".

Do you think I should swap that drive or not?

(added difficulty: that server is around 400km from me ... I would have
to direct an employee there to swap the hdd ...)

Migrating to RAID6, sure, would make sense, but this would need a
kernel-upgrade and involves quite some work. Right now I have
2.6.25-gentoo-r7 there :-(

thank you all for your replies, Stefan
