Une amie m'aimerait que je récupère ses données de son HDD externe Seagate Barracuda 7200.12 1T
J'ai déjà réussi auparavant cette opération sur divers disques mais là, le problème semble différent... plus sérieux.

Ne voulant pas faire de bêtise, je m'adresse à qui veux bien m'aider.
J'ai un warning : number of heads/cylinder mismatches 255 (NTFS) != 1 (HD)
Voici différentes étapes :
Code: Select all

Note: Correct disk geometry is required for a successful recovery. 'Analyse'
process may give some warnings if it thinks the logical geometry is mismatched.

Warning: the current number of heads per cylinder is 1
but the correct value may be 128.
You can use the Geometry menu to change this value.
It's something to try if
- some partitions are not found by TestDisk
- or the partition table can not be written because partitions overlaps.

any data; even if the partition is not bootable.

The harddisk (1000 GB / 931 GiB) seems too small! (< 4271 GB / 3977 GiB)
Check the harddisk size: HD jumpers settings, BIOS detection...
The following partitions can't be recovered:
