Do you have a Hard Disk Drive as your Master Drive?
Yes, it is my only hard drive in this PC.
Thought so, its a bug in the Windows 10 OS that Microsoft still hasn't fixed, all OS's before 10 never had this issue.
If your Master Drive is a HDD then this will occur but if you have a SSD as your Master Drive and a HDD for your second then this issue will not occur. Back when i had a HDD as my main i had this issue and i found that no one else had found a fix for the issue yet. I emailed Microsoft and they acknowledged it was a known issue.
I have a 250GB SSD and a 1TB HDD and i have had no storage usage issues since i switch my main drive to SSD and pulled my HDD down to second.
