I have and semi-old hdd (magnetic one, not ssd) and I intended to use it as system drive for my new NAS.

So I've run SMART selftest on it and it ended with status "Completed: read failure". However, badblock complete the destructive test (so 4 passes) over the drive without errors. Which of those two programs is more likely to be right?

  • How much do you value a stable operation of your NAS? – Sven Mar 11 '16 at 10:53
  • I do. I just don't understand how those two tools can give different answers. – graywolf Mar 11 '16 at 11:11
  • They are each performing different tests. – Michael Hampton Mar 11 '16 at 15:12

Think about what you're asking...

"Which of these tools is going to give me the best result on a disk of questionable health?"

If the disk is this unhealthy and reporting errors from either of these tools, you should not use it.

Neither S.M.A.R.T. nor badblocks is capable of detective every disk failure condition, but as a general rule, errors are bad.

So proceed at your own risk, but the right thing to do is to find another drive to use for this purpose.
