Merci pour ta réponse .
Par contre je ne vois ou ça parle d'un hddss.bin de mon disque dur dans ce tutorial là (par contre dans le 1er oui, mais celui-là résoudrait mon problème :
Tutorial 2: Removing the HPA without altering data (use this tutorial if your data is still intact however your 360 doesn't see the disk)
1. Connect your original 20GB drive to the PC.
2. Start your PC up and in your BIOS make sure you select boot from CD first.
3. Restart the PC booting off the MHDD bootable CD.
4. If MHDD doesn't start automatically for you, or you're using a USB Boot disk type: MHDD and press enter
5. MHDD will identify hard drives connected to your PC. for example, for me it identified:
3. FUJITSU MHV2020BH 0093002C NWxxxxxxxxxx 39,067,967
6. Enter the number corresponding to your xbox 360 HDD and press Enter. (in my case number 3)
7. You will now get to a blue prompt:
MHDD>
Type: NHPA (and press Enter)
8. Do you want to set Native LBA address (y/N)? - type: Y
9. Native Maximum LBA address: 39070079 Continue (y/N)? - type Y (these values will be different on 60GB and 120GB drives)
10. You will get the following message:
Fail. Try to re-power HDD.
Done.
11. Unplug the power cable from your xbox 360 hdd
12. wait 10 seconds
13. Plug the power cable back in.
14. Type NHPA (and press Enter)
15. Do you want to set Native LBA address (y/N)? - type: Y
16. You will get the following message:
Working ...
Done.
17. Now unplug your power and data cables from your xbox 360 HDD (in that order: first power cable, then data cable) and connect the HDD to your xbox 360.
