I've been looking at the WD30NPRZ and WD20NPVZ drives to upgrade my Bolt and the only ones I seem to find that say that they're new were manufactured in 2016. Everywhere that I've been looking it appears that WD has discontinued these drives. What is Weaknees using in their 2TB and 3TB upgrade kits? I can verify that the WD40NPZZ definitely still doesn't work with Hydra. I found a deal on that drive before I checked back here and found all the issues with the latest upgrade. But, I thought I'd give it a try since it had been a while since I saw anything posted. After getting stuck on the "Starting UP" screen, I put the original 500mb drive back in and everything came back on as normal. Just thought I'd check in and see if WD has abandoned this series or if it's been replaced with something else. I know there are a few possible Seagate replacement drives out there, but it sounds like the external drive install option seems to be the better way to go if we can't get newer drives for our upgrades.
