I think that this is because the extended partition contains the extended |
10 |
partition table at its boot sector. A primary partition at the same position |
11 |
does not and therefore has a different offset. Having spent some interesting |
12 |
white-knuckle-ride moments with testdisk, I realised that carelessly |
13 |
switching between primary and extended/logical partitions is not something I |
14 |
would like to try again - unless I am playing around in a test environment. |

Do you mean primary? |
