It's not actually missing, it just won't show in modern apps lol. I can assign whatever letter I want, it just won't show up in "Storage" modern app after I reboot my computer

Well that's how it is with computers. Trials and errors until we figure out what's wrong. Thanks for all the ideas so far.

I did "attributes volume" on all my volumes and all of them reported "No" to everything except my System reserved that said "Yes" to No default Drive Letter.

I found out that if I reboot my computer, my drives disappears. But if I change the letter, the second I do it they come back. I'll try to run Drive Tools and see if it fixes the issue.

EDIT:...

Well it was associated with the letter G before and I could see them, I switched it back to F, because that's what it was prior formatting. So I guess if they would disappear again if I do so. That's...

Okay what the hell. I changed the letter for my F Drive to G and they showed up. It makes no sense lol.

Okay so, a lot happened since last night. Somehow I couldn't boot into Windows so I had to do a Start-up repair but it couldn't fix the problem so I had to format. I'm on a fresh Windows now and my...

I always installed Windows without unplugging my other drives, oops. I'll fix that tomorrow.

Good news, most of my partitions show up in Storage after I deleted the letter associated to System Reserved, yay! Bad news, trying to switch my drives on MOBO prevented me from booting into windows....

Disk 1 is an SSD.

I have no idea about the Page file and Active Partition lol. I doubt I messed with these. I'll try to switch my drives over to their appropriate slots like you said.

Edited my post.

Yeah but Here's what I get when I click on manage storage spaces: 143394 .
And here's what happens when I click on create a new pool and storage space: 143395.

Here you go :143379

I looked into the post you linked me but nothing worked on my side.

I can see my hard drive partitions in "Explorer" but if I go to "Storage" they won't show. Here's a screenshot of what I mean. Any help would be appreciated, thank you!

Best regards, Jesse...

Any way to fix that?

EDIT: Well, I turned on my computer today and I was about to buy an app without problem, I don't know how it fixed itself but thanks for your help @AmericanPharaoh

Hello there,

Thanks for your reply. I did the first three methods and none of them worked. So I scrolled down and tried to use Microsoft Account Troubleshooter and it found issues. ...

Hello there everyone! I've been trying to purchase apps and in-app purchases for a few days and I always end up with "Give it another try. Something went wrong. SVC-Service-QueryOrder" I've done...

Well I installed Anniversary update and Dism /Online /Cleanup-Image /RestoreHealth worked lol. I'm doing an sfc /scannow right now and I'll reboot to see if my issue is still present. Which was...

Okay, here's the results of the commands you asked me to do: 96846.

Yeah I did read your tutorial about that earlier but I wanted to see if I could fix it with DISM, [emoji4].

Well I copied and pasted your command haha. I will try again tomorrow, it's getting late here and I'll post back as soon I get home from work. I greatly appreciate your help also!

Well it is mounted as "I": 96735
