Have you checked the partitions, partition flags, and partition boot |

Do you have sys-apps/smartmontools installed / smartd running? |
| 38 |
|
| 39 |
If the boot sector has wear problems, SMART may show those |
| 40 |
bad/reallocated regions on that drive. Not sure how that works with the |
| 41 |
TRIM filesystem on SSDs. |

Hope this helps. |
