Mismatch in Used Space Display on OCZ Vertex4 128GB SSD with Windows 7: How to Resolve

Honestly, I didn't know how to name this topic so as not to distort the problem.

Well, I have a W7 and an OCZ Vertex4 128GB SSD. However, I noticed at the very beginning that the mass of all files on this disk does not match the one displayed in its properties. I've screwed it up until now, but I don't want the disk to get full as it's the system partition.

Here's a comparison:

Disk management screen:


I'm not sure, but I don't think I have any system restore or backup set up. Anyway, I didn't set them up and I don't see them in the system.

I don't know if I am missing any obvious thing that takes up space, but I hope the disk is not damaged because I have never experienced something like this before. The disk scans themselves etc. show no errors.

Enable showing hidden files and disable hiding protected files and check again.

You can also use e.g. http://www.uderzo.it/main_products/space_sniffer/

Most likely you checked folders and> properties, i.e. it shows you the total weight of each file in each folder - some files have different formatting than the disk itself, hence different data.
We see this effect when trying to copy the file to a flash drive, in the properties we see that the file takes xx gb in the properties of the disk itself (flash drive) there is also adequate free space and when trying to copy the message pops up - not enough space on the target medium because the format is different.

The above is an understandable translation into "peasant reason" and practically ...:
You check with the method from 1 part 1 picture only how much all files HAVE, not how many they TAKE on disk x.

If you want to know more read about physical and logical disk structure.

Hope I helped- my first answer!

Use this and show the screenshot:

@ Kolobos. The photo was taken with hidden, but not with the protected ones shown. And here is a shock, because there are 2 files on the disk, 12 GB and 16 GB each.

Do you know what these files are? Can you delete them?

@ boku95. I know a bit about it, but I don't know what the possibility would be for this difference to be 30GB

You have hibernation enabled and the latter is the swap file. Why is it so big?

I do not know, I did not set up the swap file because first of all I do not know about it, and by definition I do not need it because I have 16GB of RAM.

You can disable hibernation as long as you do not use:

You can also change the virtual memory size:

Then set a smaller one.

So far, I do not turn off the virtual memory, I reduced it to 4GB.

However, not to spoil it. I'm using sleep on my computer, is it the same as hibernation?

So.

So I will leave this option. I meant more about where the space is from, and it has become quite a lot due to the amount of RAM. On an old 2GB PC, I just didn't notice that. Thanks to everyone involved, especially to Robert. Regards.
