I got a Razer Blade 15" Base model as a Christmas gift last December. It has been nothing but a burden ever since. I found THIS /razer-blade-pro-2017-2tb-hard-drive-not-showing-up.37957/ which is a post of someone with a different Razer machine having the exact same problem I have. This has happened to me four times now, the first 2 they replaced the hard drive, the third they gave me a brand new machine, and yet, not long after receiving it, I have the same problem a fourth time. I have been careful to only download good software from reputable companies, and in fact only used the HDD to store games, including Steam games (notably no mods!) and blizzard games, and NOTHING ELSE. I have tried every data recovery/partition manager/pc health monitor/fixer program I can think of, every fix I read about online (chckdsk, disk management, restarting OF COURSE, bios, etc) that wouldn't void the warranty (apparently I need it!), and, as I said before, I have sent it in 3 times now, about to be four. I'm creating this thread to hopefully get word of this problem out there, and maybe get a solution I haven't thought of from someone else out there.
