In theory either a write to that sector or a successful read should |
12 |
trigger a relocation. |

In practice, I've never seen a drive actually do this - maybe I just |
15 |
manage to pick drives with braindead firmware. When I write to a |
16 |
pending sector, the pending sector count goes down, but the relocated |
17 |
sector count doesn't change, and usually in a few days I have another |
18 |
pending sector. |

The last time I had a drive fail I was running md raid, so a scrub |
21 |
fixed all the pending sectors automatically, but the drive firmware |
22 |
wasn't doing its part to relocate them. Either that, or the drive had |
23 |
run out of spare sectors and wasn't reporting this via SMART. |
