badblocks -wvs (which takes forever, but in my experience is quite good |

at make failing disks actually fail ;) |

During the test you can monitor the smart attributes (smartctl -A, esp. |
| 8 |
the reallocated sector count) to see what is actually going on. |

Warning: backup your data as badblocks in destructive mode will wipe the |
| 11 |
disk clean. |

Also, you can run a SMART offline long test (smartctl -t long), which |
| 14 |
will scan the whole surface. But on most disks the test stops at the |
| 15 |
first error, so you don't get a complete picture. |

That's just a part of it. Attribute values and the error log actually |
| 21 |
provide useful information about the status of the disk. |
