I reread it, and that indeed seems what they are claiming. I still think this extraordinary claim needs more evidence to be accepted as true. I think SATA has two connectors because one runs to the power supply, and the other to the main board. If that power connectors carries data, how does that data get to the main board? Is the cable split? If so, why would they do that if there already is a data connection to the cable? Or is this a way for a CPU in the PSU to power off of the drive if things go really wrong?
