Missing Space on C Drive (Crucial M4 SSD)

post #1 of 12
Thread Starter 
I currently have a 64gb Crucial M4 as my OS/APPS drive (Windows 7). The drie currently shows ~5Gb free of 59.5GB. However, when i show all files/hidden folders then right click properties on all the items in the C Drive, it shows that these are taking up about ~30GB. Where is the additional ~25GB? I have already cleared temporary files using disk cleanup and used CCleaner. Restore points are turned off.

Any ideas?

i had the same problem after a botched windows install on my new (at the time) ssd. copying everything off to another drive and performing a secure erase (then transferring everything back) solved the problem

btw...acronis migrate easy is the chit for copying drives back and forth (and the trial version is free and fully functional)

Go into disk management and see if it's being stupid and has a part of the drive unpartitioned

You should have ahci enabled in bios before installing windows on any new ssd.

How much ram do you have? Pagefile maybe? I think Windows by default automatically sets pagefile twice the size of your ram. I upgraded from 8gb to 16gb of ram few weeks ago and noticed I lost large amount of space.

Use that. It will show every file/folder on your drive and how much space it uses. Anything taking up 25 GB will be easy to spot.

It is likely your hibernation.sys file used for hibernation (S4). Hibernation.sys is equal to the amount of system ram installed.

Look in my guide under "Immediately after installing Windows:" and disable hibernation and shrink the page file and look over other things in my guide: http://www.overclock.net/ssd/1156654-seans-windows-7-install-guide-optimization.html'

Also check out the "System Maintenance:" section for free space sniffer, it can help you locate what is taking up the most space. And run CCleaner Enhancer and such.

It is plausible but he never listed the computer's specifications.
