Personally I would trust nothing less than a dammed

good thrashing

from badblocks -svw ideally or -svn if the drive has

data on it.

Then an smart offline check to be sure the

pending/reallocated

sector counts have no increased.

Before commissioning a new drive a do a badblocks -svw

atleast 3

times without any counters increasing (something there

are bad 

quoted

sectors I just want to flush them out early) then I do

some short, 

quoted

long and offline smart tests.

Then I add to the array, then I run check a couple of

times.

To be explicit:

This would mean to run "badblocks -svn" on md3 or sdb or
sdb3 ?

just to make sure I understand you correctly ...

Does that step take long?

Stefan

This step is run on the drives that form the array so sdb... and it can take a long time.. depends on how many times you run it through and how the drive is connected...
