Hello everyone! I have been trying to follow the posts regarding the set up and purchase of an external hard drive for the 7216 HD DVR... I see that Verizon reccomends using the Western Digital – WDBACS5000EBK-NEVZ – 500GB (or the 1tb model)... My 1st questions is where can I purchase one? I can't seem to find one anywhere online and of course Best Buy is clueless... My 2nd question is... Are there any other eSATA drives' that would work if they are no longer available? I can't seem to get ANY help from calling FIOS and the one rep said I would have to upgrade (extra monthly charge) my box to the newer black models... Can anyone PLEASE help!?! Thank you...
