Thanks. I was confused by the output, which said:- "SMART overall-health self-assessment test result: PASSED"
The sum total of what the disk thinks of itself. If it ever changes to FAILED you try save what you can before going for lunch. In my limited (3 cases) experience, disks are *$@@ed well before this goes FAILED.
Run the short and long tests, -t short and -t long, waiting for each to finish. Then run smartctl -a and check for errors.
Both tests completed without error.
The disk doesn't find anything much wrong with itself. If the reallocatedsectorcount is also 0, you should have nothing to worry.
Perhaps it's not a disk error but a controller or driver error
More likely now.
Would that show up in these tests?
No, unless it corrupts some transfer such that the smart command "tell me your status" becomes "do a low-level format". Volker -- Volker Kuhlmann is possibly list0570 with the domain in header http://volker.dnsalias.net/ Please do not CC list postings to me.
