I am trying to recycle the hard drive from a defunct HR20-100 Directivo. I tried it in Windows, OS X and Linux and although it showed as a 2.2 TB drive (odd, it's a Western Digital SATA 320GB drive) I couldn't get anywhere near reformating or erasing it; I get messages I can't write to it, that it has no partition map, etc. I've used it with 2 different USB enclosures; same result. Is there any way to make this usable? It was working before I took the DVR out of play. Rob PS: I do have the right to mess with this drive; no need to replay with posts about leased equipment, yada yada.
