What about reformatting
If I follow these instructions and I already have some store on the HD do I need to reload them to the 622 before doing this?
This is a know compatibility problem between these Seagate drives and the 622/722 it has to do with the drives sleep mode. Here is link to a utility and instructions on disabling it. I also recommend plugging the drive into a switched power outlet such as on an A/V receiver so the drive doesn't run 24/7.
