More likely than not, it's either the paging file or system reserved. You can check to see if it's the paging file (Virtual memory) by going into the advanced system settings.


1. Open System in Control Panel.


2. On the Advanced tab, under Performance, click Settings.


3. On the Advanced tab, under Virtual memory, click Change.

You should be able to now see how much disk space is allocated to virtual memory. It may also be the system reserved partition as well. Both of these are normal and should not be altered.

Hi!

Thx. for the answer. But it's not the virtual memory. I do not use virtual memory, or system restore, or indexing. i already checked this things. i tried ccleaner, the stuffs of windows, ASO3's Disk Explorer, WinDirStat, it's nothing. 18,7 gb is vanish.

That thread offers no resolution or explanation of what their issue was so what's the point of linking to it? Is there something I missed?

When you ran SpaceSniffer, it most likely popped up a bunch of error 5 access denied errors. Those may have been your unaccessable space. If you right click on the spacesniffer.exe and run as administrator do you still have unaccessable space?

I know that doesn't help on your original issue of missing space but it at least may help with the unaccessable space issue.

It might even actually just be the normal amount of space that's reserved for the system plus the amount that generally is never available on a drive despite it's listed capacity. For example, your 1TB drive only shows 931GB.

And what do you mean by "I don't use virtual memory"? Do you mean you have the paging file turned off in the advanced system settings? That's a poor decision if you do, but of course, it's your rig. I'd double check because the amount your missing would seem to be the likely amount reserved by the system for the paging file plus the normal amount that the drives capacity never adds up to.

The capacity of an HDD reported to an end user by the operating system is less than the amount stated by a drive or system manufacturer due to amongst other things, different units of measuring capacity, capacity consumed system and/or redundancy.

Check here:

http://windows.microsoft.com/en-us/windows/change-virtual-memory-size#1TC=windows-7

I'd suggest that possibly there is space allocated for it on both your drives, but maybe not. If that is the issue, I'd suggest manually setting it to only 4-8GB on one drive or the other. The secondary drive would probably be the better choice if both drives are of the same speed, or whichever drive is the faster of the two. Don't forget to click "set" next to the settings if you do make any changes or they will not be saved, even by clicking ok at the bottom of the settings window.

I'm bowing out of this thread, the OP seems like a jerk only giving the least amount of info possible and expecting others to guess what the issue is. If the real problem is a new file and not missing space then duh, search by date created in something like directory opus to see what is new.

The paging file shouldn't ever be turned off regardless of drive type. At least one drive needs to have some space allocated for it or you seriously run the risk of some applications, which try to directly access virtual memory, to blue screen or for the system to exhibit slower performance as some of windows routines want to access strange memory locations with no discernable reason for it. Microsoft strongly advises against having it disabled regardless that some sites like Puget systems recommends it.

But aside from that, I've seen a lot of users "think" they have changed the settings there but had failed to click on "set" after making the change and had in fact not changed anything. Also, having a page file on the SSD is unlikely to cause any kind of premature failure due to the number of writes, regardless what anybody might say to the contrary.

When you do the reinstall, make sure to do it using the custom option and delete all the existing partitions on the drive, then recreate a partition using all the available unallocated space (Make a note of all unallocated space as well so you actually have a distinct number to refer to regarding the actual drive space later) and then point you installation to that partition. All of this can be done using the windows installer, which you probably already know.

Good luck with the process.
