Ok now this takes the "Most egregiously creative misuse of ZFS" award :-)

I doubt ZFS can help if badblocks "didn't work". It would help to know what was 
the problem with it, but generally a destructive test reveals a lot.

OTOH, you can also do better by writing a small program which writes random 
data + its checksum (4K data fro /dev/urandom + md5) to the whole disk. A 
second program can read the chunks back and report locations where the data 
doesn't match the checksum.
