Win 7 Boot Drive Missing ~20GB

post #1 of 21
Thread Starter 
I have noticed recently that around 20GB of space has just disappeared of my C drive, in the last week or so.
The drive is an 120GB OCZ Vertex SSD so that is a huge chunk.

How can I determine whats taking up this space? Disk cleanup was no help.
See below for the discrepancy.
Not sure where that 21gb for files comes from.

- System recovery files/dumps I have cleaned with disk clean up.
- The page file was set to 12gb. I have now turned it off but no change.
- Hibernation not sure, I use sleep when not in use.
- TRIM is enabled: DisableDeleteNotify = 0 (Windows TRIM commands are enabled)
- Only other thing I can think of is that I had 6GB of RAM and added another 6GB today, shouldn't affect it afaik.

Check your downloads, I forgot to change my directory once and it filled my SSD.
post #8 of 21
i do suggest a malware scan, there is malware/bloatware that will fill a drive on its own over time

You have to go into the Command prompt and disable hibernation yourself. Right click on it and open it as Administrator. Type this in "powercfg -h off" without the quotations, then press enter.

For the paging file, check it again to see if you really did disable it or not. You should get 12GB back. If not, disable it again then restart computer.

Yup the 12gb came back after reboot smile.gif
Thanks.
Only ~5gb unaccounted now.
If I disable hibernation, will it also disable sleep with it? I like that since it saves me from turning on/off the computer many times a day.
