As Windows updated or folk use system cleaners (not advised) the registry flag to not check for this was removed. The drive is either the recovery drive or something else and before this, Windows was told to ignore this drive.

Hello,
I have a Series 5 Samsung Laptop that has suddenly started telling me that the D drive is full and I need to clear up space. However, I do not remember there ever being a D drive. But the real question is why would there be a D drive that is only 488mb in size? Not to mention the files are hidden so i do not know what is on the partition. Any idea what it could be?
