Input: I purchased this item to expand the storage space of the MOXI retail unit which comes with 500 GB built in. I have Charter as my Cable provider. Everything worked perfectly. I connected the unit following the instructions in the box. The MOXI said it recognized it and was going to format it which just took a minute or so. I then restarted the MOXI and I had the extra 1TB of space. Contrary to some other reviews here the MOXI continued to show the recorded programs on the original HD and the percent of disc space used was for 1.5 TB so it was a true extender, not a replacement for the original drive.
