November 4, 201213 yr Hi mate Put your data in a new safe disk, and tray to preclear it, at least two or three full cycles. The overall smarctl says status passed,so reallocating the bad sectors should be enough, but anyway, The disk colud fail again.
November 4, 201213 yr Also pass a long smarctl test, smarctl -t long /dev/sd* But it's a quite cheap WD20EARX, so just replace it.
