What's the difference between -M alone and -M -A together?
'-M' marks all failed blocks as non-trimmed, while '-M -A' marks all failed blocks as non-tried.
'non-tried' areas are read in large blocks. 'non-trimmed' areas are read sector by sector.
'-M -A' is better used when the read errors were not produced by bad sectors, but by some general failure like a drive that stops responding.
Best regards, Antonio.
