That would be badblocks, which can do a read-only or a destructive
write-read-verify test. It'll even do a nondestructive read-write-
read-verify-restore cycle so it puts the data back when it's done.
You can tell e2fsck to do a readonly badblocks scan with the -c option
and a nondestructive write-read test with -cc.
Takes a loooong time, though.
And yes, the SMART tools can tell you a bit about what the drive thinks
about its own health. But we all know how accurate self-assessments can
be...
