Hopefully just bad luck (a failing drive, or a power hickup), but a |
| 7 |
kernel bug can't be ruled out. As for bad maintenance... with any |
| 8 |
data that you value, a regular disk inspection is needed: a maximum |
| 9 |
mount count of something like 15 or an interval of two weeks. |

Use tune2fs to set the checking interval to 1 week. Or better yet, |
| 16 |
to 1 day for now, to keep inspecting the disk everyday for a while. |
| 17 |
Use 'tunefs -l ...' to see the current values. |

It won't protect you when the disk is going bad, nor when the kernel |
| 23 |
has bugs. It only protects you from losing data during a sudden |
| 24 |
power loss. |
