Re: The compatibility list
You're not a disk maker. Stop pretending you are.
To be fair this is not exactly new. Most large computer vendors released their "own" disks with their own firmware. As an example Sun was shipping its own disks that were all manufactured by others. Same goes for other vendors.
Granted, Sun (again as example) didn't spit on you if you stuck botgt standard Seagate instead of its "own".
