I bought this harddrive:

It's a WD scorpio 2500BEVS so it should be compatible with HDDhackr.
I made a bootable USB drive and flashed the firmware.
The bios now says that it's a Hitachi drive.
Then I created the 0/2/3 partitions.
I plugged it in my old HDD xbox-casing and connected it to the Xbox.
However, the Xbox says: "No device connected"
What did I do wrong?
Here are some screenshots of the drive in Windows
