Windows 10: Windows 10 modern apps won't show any HDD/partitions except the one it

In Disk Management, highlight the System Reserved Partition (G: ) and choose Change Drive letters or Paths, pus the Remove button to remove the Drive Letter.
Shut down the computer and open side and switch the location of the SATA Data cables for 120GTB Windows drive with the 1TB Storage drive, swap where they are plugged into on the motherboard,

 

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 drives still won't show up in Storage. I did manage to swap my wires on my motherboard. I also installed Windows with only my SSD plugged in. I've attached screenshots of Explorer and Disk Management.

 

These are just a W.A.G *Smile
1. Check services and see if Storage Service is running (default is manual/trigger).
2. Disk D: being almost full maybe (yea, makes no sense, but ....)
3. Try and change the driver letters to say I, J, K using disk management.

 

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

 

Glad you got it sorted out *Smile

If you change it back to F, do they disappear again ?

 

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 odd.

 

Couple of cool little utilities. DriveCleanup might fix the issue so you can go back to D,E,F

Drive Tools for Windows
DriveCleanup V1.4
Tools für Windows
Device Cleanup Tool V0.7.1

Edit: Be careful with Device Cleanup, it could remove something you don't want removed (like WAN Miniport stuff, if they aren't active)

 

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: Drive Tools didn't help, they still won't show up until I change a letter of one of my drives.

 

I'm wondering if one of the partitions/volumes (F probably) has got the Hidden Attribute Set. I would reboot so that they disappear and are D,E,F .... then use diskpart to check the volume atrributes.

Open a Command Prompt as Admin
diskpart
list volume
select volume # - Replace # with the volume letter
attributes volume - List volume attributes (Read-only : No, Hidden : No, No Default Drive Letter: No, Shadow Copy : No)
attributes volume clear hidden - Clear hidden attribute on volume (if you find one)
exit - leave diskpart

MiniTool Patition Wizard can do this also and is great for managing partitions.

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.

 

yea, that's normal for system reserved partition, so much for that idea *Sad

 

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.

 

If that's a Western Digital HDD, there is some info that might be applicable half way down the page ... Drive Letter Disappears after Reboot.

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
