DirecTV Hughes SD-DVR40

[ryan954]

I purchased a DirecTV Hughes SD-DVR40. It will record up to 35 hours. I have an extra Maxtor DiamondMax Plus DX740X (6L080L4) hard drive. It is an 80GB drive, that runs at 7200rpm. It supports ATA 100/133 and has a 2MB cache buffer. Can I replace/add this to my Hughes DVR? What will I need to do so?
