Hi, Just got DirecTV installed today (three HR24-100's). I bought external hard drives (WD20EURS + Thermaltake BlacX, per the recommendations on this forum -- thanks!) and hooked them up. My install process was to cut power to the HR24, power up the external hard drive, connect it to the eSata port on the HR24 and then power the HR24 back up. I think the HR24 is using the external hard drive, but I'm not sure how I can verify that it really is. Any recommendations? (I'd hate to start recording my stuff, only to realize later that it's going to the internal hard drive.) Thanks!
