Solved 1TB of HDD space missing completely

[R3B3LCAUSE]

My laptop has a 2TB hard drive, but a few months ago over half of it completely vanished. Windows explorer shows that my C drive is now only 911GB. I believe the issue came about after I uninstalled Ubuntu (I dual booted for a while) and I thought that perhaps the space just didn't get reallocated properly so I checked in disk management and didn't find an "unallocated space" block. I tried error checking my hard disk, but this didn't fix it either. I have no idea how to fix this problem

Run this command in elevated command prompt:

vssadmin list shadowstorage

Maybe the shadowstorage (restore points) is eating your C partition.

I also recommend to run WinDirStat. It shows you in nicely colored graphics were the big blocks are. When you click on the blocks it will tell you what it is.

I tried WinDirStat. It showed me the contents of my C partition, but not the space that is missing (not a part of any partition)

Maybe a screenshot will shed some light,

Did you check the shadowstorage - WinDirStat will not show that.

Used is 6 GB, max is 10 GB. I don't think that is the issue

You don't have a 2TB disk, you have a 1TB disk, same size as mine.

Maybe I was mistaken and I actually have only 1 TB. I would still be missing 70 GB, what could the reason for that be?

That's normal; drives typically have a formatted capacity of about 93% of their advertised capacity.

How can they advertise more than they actually sell you? What is the other 7%?

Here's 846,000 Google hits explaining it.

Generally--there are 2 ways of measuring capacity and guess what? The HD manufacturers use the method that gives the largest number. Shocking, I tell you, shocking.

The 7% is the difference between the decimal number and the binary number.

1GB in decimal is 930MB in binary - but that is always 1 Billion bytes. Unfortunately the PC knows only binary and confuses us. LOL.
