There are pins missing in the middle to indicate keying.
You must jumper the drive to Cable select for it to be "seen"
Hooking the connector backwards almost immediately frys the drive.
Ontrack data recovery usually charges $3500 to recover data from broken drives.
I have a 100 percent success rate with them so its a matter of how much you want the data or not.
Drive savers is another good company for this. The pin missing below is Normal.
