Review on WD 500GB AV-GP SATA 3 Gb/s Intellipower 8MB Cache Bulk/OEM AV Hard Drive - WD5000AVVS by Keith Maynard

Bought two hard drives on May 1st 2017. One of them was used in a CCTV DVR but after a few weeks the DVR stuck on the loading screen hang. I tried the same hard drive on another DVR and a day later the DVR got stuck on the boot screen too. Both DVRs worked great with other hard drives from the last year. I believe the hard drive is bad and I won't even try to use a different one for fear it will damage the other dash cam. Now I have two spare DVRs.
