Sudden loss of hard drive free space

I've had a sudden loss of my hard drive space. I've deleted alot of stuff, like over 20GB, more then just a few times and it just disappeared in less then 2 days. I've read some topics here with the about same problem and tried what they sugested there: to use software like WinDirStat, TreeSize Free and SpaceSniffer. But they just won't show me my whole hard drive. The stop at 50% and show it as if they have scan the whole 100%. And its gettind really bad, had gone down to 4mb free hard drive space left already... Any ideas how to fix this?

Have you run the hard drive manufacturer's disk utility to see if the drive is actually defective?

You could also run checkdisk--that might take several hours.

Have you run Windows 7 disk cleanup?

How much space do you have allotted to System Restore?

Have you been doing a lot of installing and uninstalling?

Have you done a complete virus/malware scan?

Can you post a picture of your Disk Management, showing partitions and sizes?

I think I found the solution to my own problem. I found those 154gb worth files (294 files), they were at C:\Windows\Temp. And the reason none of the software I tried could read that folder was because it was protected by administrator rights. And just incase, I've done everything you sugessted except the first thing, couldn't find that utility. But I quess my harddrive is fine since I found were to did all of my memory disapeare. Thanks for you help!

In start Search type in cmd then on the cmd.exe right click and select run as administrator. At the blinking cursor type in chkdsk /f and reboot. Chkdsk will run at startup and may take an hour or two. This will find and attempt to fix disk errors.

Minimum free space on hard drive?
I have a 500GB SSD and 26.1GB free of 489GB. Can I take that 26.1GB down to zero without any issues or should I start deleting stuff now?

Hi everyone, I installed Ubuntu on my computer a few months ago and created another partition for it on my 1TB hard drive. I didn't really care for Ubuntu so I decided to delete the partition it was on. :geek: That might have been a mistake. :( Well, now there's 87.68GB of free space on...

Hard Drive Free Space
I know that it is necessary to keep ~15% free space on the system drive for proper function, but what about a non-OS drive that is used only for storage? My video archive drive never seems to get fragged, so I doubt that I will need freespace for defragging...any other reason to need it?

loss of hard drive space
I'm thinking of upgrading to Windows 7, but wanted to know which is best? I was thinking of going to ultimate but is it worth it? But my main question is why am I continually losing hard drive space. I recently updated to Vista from XP and that's when it really started. (That I noticed anyways)....
