I have an hr21-700. I removed the 320gb and installed an 80 gb hitachi SATA II drive just to see if it would work before making the plunge for a 1 TB. I turned on the HR and she did an immediate format. BTW, that drive has been in my computer for 2 years. I recorded some hd & sd programming, about 30 minutes worth. I didn't see any difference between the hitachi and the orig. 320 WD. Again I'm only playing with this for a couple of hours so i don't have any results on video quality, problems etc.
I did have a few hiccups like I am not authorized to record this program (i think because my favorites changed) and an unauthorized access card (762). I re-installed the card and then no problem. Once i redid my favorites everything seems normal. The guide has to reload so now only a few programs are available in the guide.
That was information for everyone on my experience. I now may buy the WD WD10EACS, WD10EVCS or the WD10EADS not sure yet. The EACS AND EVCS have 16m/b buffers while the EADS has a 32m/b buffer. I was wondering if the buffer size helps or hinders video playback and is a determining factor in a HD choice for the hr-21-700. Except for power consumption all other specs for those models are about the same. Any advice on this or any other internal HD appreciated in advance.
Lastly, if I hook up the original 320gb with all my programs on it (had about 20% space remaining) and the new 1 TB drive to my computer do you think a program like acronis trueimage or ghost etc will make an exact copy of the 320 to the 1tb?
