It would be pretty unlikely to hit something there, since that doesn't
check the data in files.

That should run badblocks, but you might want to run it yourself since
you have more flexibility in the test. If the disks aren't that big
letting badblocks repeatedly read and write the disk might be a good
idea. With bigger disks this can take a long time.

There might be something odd about that model of drive. Once a successful
read has been made from a blocking that has a pending reallocation, it
should be reallocated.
