`badblocks` sadly writes the same pattern on every block, AFAIK, so if
the drive just remaps new logical blocks to already used physical
blocks, `badblocks` may be convinced that the drive works fine even when
it doesn't.
So, if you want to use `badblocks`, you may want to do it on an
encrypted partition (that covers the whole device) rather than on the
raw device.
