I have asked this question: Is there any way to check for badblocks that use uncompressible data and also also can do multiple pass?
Apparently I expect an answer to come up with a good way to test badblocks. But a user @dirkt is trying to mislead my question by posting his opinion. There is has no source code to support his opinion so I have to argue. He is saying modern disks does not need to check for badblocks, but at least what to do for non-modern disks? Anyway I just want methods to test badblocks not want to debate on opinions. But it appears this user has more reputation and the question get flagged as opinion-based and closed.
So what to do with someone with more reputation trying to mislead my question into an opinion based question? It appears he abused his reputation to express his opinions not really want to provide methods to solve questions.
