Hey everyone,
I've had an ongoing issues with my Windows 10 computer I assembled several years ago. About 3 weeks ago, I logged in and everything that was on my 2nd harddrive D: was either missing or was a blank icon. I can't find any signs of the harddrive under my PC, disk management and I've ran the troubleshooter that windows recommends. The only place I find any evidence of its existence is in the Bios where it gives me the option to change the order it starts in. I've updated the computer to to the latest version of windows 10 and all drivers are also up to date. Ive swapped out Lsata cables and ports on the motherboard. I've read that this is an issue that has been found on windows 10 devices but I have followed all the advice I have read, without luck. Has my harddrive failed or is there something I'm totally missing? I appreciate the help!

I can not get any pictures to appear on here and my phone doesn't even give me the option to reply

I have never used Diskpart, how should I proceed?
