Si le disque n'est pas reconnu par hddhackr lors du flash, comme indiqué sur xbox-scene par TheSpecialist (on retrouve cette explication aussi sur le forum gueux):
Q. The tool doesn't detect my HDD !
A. First, make sure you are running it from dos, not from a dos box under windows. If the hddhackr does not autodetect your SATA controller (if you have an nForce chipset for example), then you can manually edit the hddhackr to support it. To do this:
1. Find the two ports that your SATA chipset uses for data communication (see the MTKediting thread for more detailed info on how to do this), basically, you need to run 'msinfo32', then go to storage/scsi or storage/ide, depending on your SATA chipset and then look for the two ports that have a difference of 7 between them. For example:
I/O-port 0x0000EFE0-0x0000EFE7
I/O-port 0x0000EFAC-0x0000EFAF
I/O-port 0x0000EFA0-0x0000EFA7
I/O-port 0x0000EFA8-0x0000EFAB
I/O-port 0x0000EF90-0x0000EF9F
I/O-port 0x0000E800-0x0000E8FF
In this example the two ports you are looking for (with difference of 7) are 0xEFE0 and 0xEFA0
2. Open the hddhackr.com in a hexeditor and search for the string 'port=MPRT' (it is at the end of the file). Now, that 'MPRT' string is 4 bytes long: 0x4D 0x50 0x52 0x54. You have to replace these four bytes with the 2 port numbers (which are each 2 bytes long, so you replace the 4 bytes in total), so in the example above you replace these four bytes with: '0xEF 0xE0 0xEF 0xA0'.
3. If you then start the hddhackr, it will automatically detect that you have edited that string, so it will skip the SATA autodetector and instead use the port numbers you've supplied
Enfin bref, le disque est flashé avec un hddss.bin de 120go mais il n'est pas reconnu par ma xbox.....
