Hi, everyone!

Badly need help! I tried everything I know, and searched online but nothing helped!

So basically I had an SSD size of 1TB.. but after a Windows update, turned into 500GB.

I had two partitions, (C) and (D), both with 500GB each. Drive (D) went missing after the Windows 10 update! Along with all my files!
When I open Disk Management, there are no extra 500GB Unallocated partitions or even un-named partitions. It just disappeared!

See my Disk Management bellow:

I also tried updating my drivers but nothing still:

Did a system restore but nothing!

I even Reset my PC but NOTHING!

Tried to search for it in CMD... I FOUND THE EXTRA 500 GB though it's hidden??? How do I get it back?? See image bellow:

Tried un-hiding it but failed, it says "This command does not work on dynamic disks nor on Microsoft reserved partitions:

You have RAID 0 array of 2x 238GB drives = 477GB.
You have never had 1TB storage.
That's the weird thing! I always had a 1TB. Had this computer for almost 3 years now, I should know I have a 1TB. I partitioned it like two years ago, 500GB for (C) and 500GB for (D). As stated above, after a Windows update, Drive D disappeared?! It's been such a big mystery.

I used my Drive (D) for games. Almost had about 420GB Worth of games. My personal files were on (C), had about 375GB used space. That's too much space if I never had a 1TB.

Verify, what physical drives you have in your laptop.
Seems like you're not familiar with specs of your hardware.

Should be 2 NVME drives (2x 238GB) and possibly one sata HDD ( 500GB or 2TB ?).
So I opened my laptop. It has 2x SSDs and one sata HDD (1TB). Removed my HDD and put it back (hehe), but still the same. You're right. HDD must be dead :(
