This is a white label hard drive that cannot actually be installed in the PC because WD has blocked it. However, you can get around this blockage with some adhesive tape. https://www.youtube.com/watch

White label. Is similar to a WD Red but not quite

A WD RED, if you break it open you can remove the USB interface.

no idea, but there are no problems

I don't know :-) I didn't open it and connected it via usb, so usb and usb controller will be the determining factors.
