Hello, I have an owned DirecTV HR-21 DVR and about every 2 years I clone the internal drive to prevent me from having to deal with an HDD crash and losing all content. I have never had issues following the directions in these forums to use gParted to do this. The snag I am running into this time is that the new HDD won't initialize when I put it in the DVR to 'prep' it for cloning. Typically I gracefully power down the old drive and then attach the new one, power on and the new drive is prepped for use. This time I am getting an error and an option to reboot which doesn't help. In the past I typically used Western Digital Green drives but this time opted for a Seagate Ironwolf 2TB ST2000NE0025 in the hopes that it would age better. The new drive is recognized by gParted without issue and the old drive works just fine in the DVR so I don't think the new drive nor the DVR have issues. All of this said, I am not sure if there is something about the Ironwolf drive that makes it unusable for the DVR. Any thoughts are greatly appreciated - especially if you have experience, good or ill, using this drive in an HR2x series DVR. Thanks in advance!
