The MBR contains only details of the primary partitions, the logical |
| 11 |
partition details are scattered over the disk, and there's no backup of |
| 12 |
either. Making your own backup is non-trivial, even if you bother. |

GPT puts all the partition information in one block, and keeps a backup |
| 15 |
copy elsewhere (rather like filesystems do with superblocks). |

That makes GPT more resilient to corruption in the first place and easier |
| 18 |
to recover if things do go bad. Remember that GPT was designed with the |
| 19 |
benefit of decades of hindsight over the limitations of DOS partition |
| 20 |
tables. |
