I bought this hard drive to repair a TiVo Edge DVR that had a 2 TB hard drive that failed. For about $33 I was able to restore a TiVo Edge DVR that normally sells (with Life Time Service) for over $900. Recently TiVo has ben offering a limited time deal for a TiVo Edge with Life Time Service for around $300 so for even that price the $33 cost of this WD 1 TB hard drive is a bargain. As stated the original TiVo Seagate hard drive was 2 TB which provided 300 hours of HD recordings while this WD 1 TB hard drive will only provide about 150 hours of HD recordings - and I can live with that. Fortunately, the TiVo Edge formats the new hard drive automatically so other than the mechanical aspects of installing the new hard drive was a breeze.

Works like a charm. Nice product and was as described in the ad. The pricing was fair and no problems just plug in and play. Thanks

Being the suspicious type, I suspect that these sites are used for “dumping.” However, this drive seems as good as any that I have bought elsewhere & I have bought several.

The drive itself is fine, but if you are thinking of putting this in your Edge or Bolt - it won't work.

Finding a replacement hard drive for a Tivo Bolt Vox is not the easiest task in the world - many will work, few will last. A surveillance device type drive, such as this, is what is necessary to get longevity. Staying at 1TB or less isn't absolutely mandatory but is what the Tivo Bolt was originally designed to handle. Getting a 1TB drive direct from TIVO (or their reseller) is six times the cost of this! Of course long term reliability can only be determined over the long term (duh) so I may end up changing this review in six months if it fails. I fully expect to get 5 years out of this drive in this application - how confident? I ordered a second one to put away for installation in 5+ years because I'm sure they will be out of production by then.

...the "Disk at Risk of Failure" error message popped up. "Unifi has detected a large quantity of bad drive sectors. Replace this disk as soon as possible before an unexpected failure results in a data loss. 344 bad sectors. I have owned it for less than 3 hours and it is out of warranty. How about that Araman Trading? You sell broke and out of warranty items?

The 500 GB on my Tivo Bolt cable/OTA started to show signs of failure. This 1TB drive was recommended as a replacement. The new drive passed all of the initial tests I ran on it, and was easy to install in the Bolt (though getting the Bolt drive cover off was a little bit of a challenge.) The Bolt recognized the drive and formatted it for use without issue. It’s been running well for a month now, and is much quieter than the original drive. Recording and playback seem to work better as well. Very satisfied so far.
