The day before my memorial weekend camping trip my HD in my dvr decided to quit on me. Upon doing some research i seen this model was the most mentioned option. Ordered it and picked it up next day, took my 5 mins to swap it out with the old one. Plugged DVR in and it booted straight up without any extra work. I highly recommend this product to anyone looking for a replacement, especially if you have a samsung wisenet dvr!!!! Easily replaced the 2TB Greenpower Western Digital that it originally came with!!!
