I purchased 3 - 2TB Fantom GreenDrives in July 2011 for my 3 Motorola 7216-1 DVRs. They all worked after initial setup, but would stop being recognized. I was getting ready to return them to get the WD drives that were recommended when they suddenly started working perfectly maybe in September of 2011. Ever since then they have all run without a hitch. I literally have unlimited storage for HD recordings. I think that Verizon pushed through a software upgrade that made the drives start working. Anyway I can vouch for these Fantom 2TB drives with my 7216-1 DVRs.
I continue to have problems with my 1TB Approved WD HDD. The HDD at this moment is not recognized by the DVR. I have gone through the process three times now to reboot and recognize the drive, but no luck.
FYI Verizon has sent me two different 7232 DVRs thinking that is the problem... but it is not. I think their is something wrong with their software somewhere. My HDD is over 75% full with my recordings but I cannot access it.
I hope they recognize this problem and get it fixed.
I am very frustrated with Verizon. When my contract is up I am going back to DirecTV. I have never seen a major corporation completely clueless on how to resolve this ongoing problem.

Many users here have observed that the OEM eSata cables shipped by Western Digital have often been faulty from the start. If you haven't yet done so, try switching out this cable. I hope you will be pleasantly surprised by the result. BTW they aren't that costly, so the experiment isn't too expensive.
