Those that live in the NY/NJ area and have Cablevision know that they changed most, if not all, of the regular channels to HD channels. So our DVR has been filling up faster than usual, and there is no way around it. Most of the popular channels are all in HD. So for the past month or so, my wife and I have been looking for a solution. Our DVR was always 70-80% full and we were constantly erasing stuff. I found the Western Digital My DVR Expander, and it was the solution to our problem. I called Cablevision customer support and asked them if it was compatible with our DVR. They said yes, and that it was actually the only one compatible, meaning that you can't just get any eSATA drive and plug it in. The My DVR Expander is formatted to function just like your DVR. I did read somewhere that only the 500 GB version is the only one compatible with the Scientific Atlanta Explorer, but the Cablevision customer support tech did not mention that.
It took one day to receive my package after ordering, AMAZING! I looked up the installation instruction on the Cablevision website and they were identical to the instructions that came with the drive. "Power off cable box, plug in the power cord for the DVR Expander, connect the eSATA cable, power on DVR Expander, and power on cable box, follow on screen instructions to format the drive." Simple right? You would think that, but I did not get the on screen instructions, so I knew something was wrong. I checked to see the about of space used, and it was still 85% full. I started to get a little frustrated, but I decided to try it again, thinking maybe I did something wrong. Followed the instructions again, and still it was not recognized. Now my frustration was starting to show, especially because I bought another one for our bedroom. I called Cablevision tech support, and spoke to high level tech guy. I explained the problem, and he said he doesn't understand why it wasn't working. He first said that maybe my DVR Expander was defective and to take it back. I said I can't do that. Then he came back and asked me if I had the 500 GB version or the 1 TB versions. I told him I had the 1 TB version, then he said that he checked with his supervisor and that this version is not compatible, and sorry for the inconvenience. Now I was furious, but I did not give up. I decided to try my own SIMPLE installation. With both the DVR Expander and the cable box powered on, I just pluged the eSATA cable to the back of the cable box, and VIOLA!!!! The on screen instruction came up asking to format the drive. It took less than one minute. I checked the space used, and I was delighted to see that it was only 10% full! The installation should have taken less than 2 minutes. You don't even have to wait for your cable box to reboot, which takes like 5 minutes or more.
Overall, I am very pleased with it so far. I've had it for two weeks now, and everything is working fine. I put my ear next to it, and I could barely hear it running. It has never gotten too hot, and I have it set next to my cable box in my entertainment center. If you are a cablevision customer, this is such a great upgrade, and it works fine. If you are having trouble, feel free to leave a comment.
