Warning: don't use 3.16-rc1
As Andi found, and it should be fixed in newest -rcs, but I just did
root@amd:~# mkfs.ext4 -c /dev/mapper/usbhdd
(yes, obscure 4GB bug, how could it hit me?)
And now I have
root@amd:/# dumpe2fs -b /dev/mapper/usbhdd
dumpe2fs 1.41.12 (17-May-2010)
1011347
2059923
3108499
4157075
and
>>> (2059923-1011347)/1024.
1024.0
>>> (3108499-1011347)/1024.
2048.0
>>>
. Yes, badblocks detected error every 4GB.
I'll update now, and I believe disk errors will mysteriously disappear.
