Windows 7: Approx. 20Gb of system disk space "missing" - Intel X25-M G2

Hello, my system disk is an Intel X25-M G2 80Gb (74.4Gb) and I recently discovered that there is a rather huge discrepancy in used disk space.



According to disk properties I have used up ~73.7 of the 74.4Gb, but the actual files on the disk are only 51.7Gb if I show all hidden/system files, mark everything and check size and WinDirStat report the EXACT same thing.



I have no pagefile on my system disk, no hibernation file and no system restores (it's actually disabled).

So any ideas whatsoever what this could be? It's starting to become rather annoying to "lose" 25% of my system disk. I've run diagnostics and haven't been able to find anything, I've googled it extensively and found others with similar problems, but the only solutions I've found are pagefile, hibernation file, system restores and of course disk cleaning - all of which I have checked already.

Hello Zeilon, and welcome to Seven Forums.

The tutorial below may be able to help you ID what may be using the SSD's space. Option 1 with WinDirStat is a good starting point.

Hope this helps,

Hello Brink,

Thank you for your reply. I managed to get back the missing space although don't ask me how exactly. After a reboot it was suddenly all there, which is weird because I've made a few reboots while trying out things after I discovered the disk space was missing and I didn't do anything in particular this time.

The weird thing is that everything indicated that it wasn't used up and even so Windows refused to acknowledge it until the reboot.

I did install CCleaner though so that's going to be a useful addition.

Odd, but I'm happy to hear that you got your space back. If it happens again, please let us know.
