why is my hard drive full

May 16, 2011 at 15:08:28
Specs: Windows Vista
I am asking for help. I have an HP Pavilion desk top. My C drive has only 7.47GB free out of 286GB total. I do not have any media stored on the C drive; outside of a few pics and wallpapers. No videos, music, or other files that require a large amount of space. I do have an external 500GB mass storage drive. I have done disc clean up and defrag. I have ESET Security and PC Tools Spyware Doctor. I have not to the best of my knowledge got a virus. I have went through the installed programs to see if something got attached to another program and is eating up space. Have scanned separate programs to see if they are clean. Have tried to contact HP for help, but have not got a response. Thank you.

So you're saying you have either a 300GB or 320GB HDD, it only has one single partition that encompasses the entire drive capacity & you can't figure out what's hogging all the space?

Have you downloaded or burned movies? Is the partition formatted FAT32 or NTFS?

I have not downloaded any movies or other media that requires a lot of space on the C drive. I download directly to my external mass storage drive. As of now; 9:02pm; I now have a read of 3.37GB on my C drive. Something is eating it up fast. I am not that computer smart, but I do try to be careful about my security settings and do regular scans and clean up along with defrag.

What is the actual size of your drive? A 300GB HDD is approx 279GB & a 320GB HDD is approx 298GB. 286GB does not fit a "normal" HDD size so there's something you're not telling us. Is there just one partition like I alluded to in my other response or are there 2 or more partitions? Did you try the program that I posted a link to?

I have a 320GB main hard drive; it only reads 286GB; I guess because of all the Windows and other core programs that are on the drive. Like I said before; I am not that computer smart. I have tried to go through what I know to do and check. I don't know DOS commands; how to ask my computer what is going on internally with the main drive. As of this response; I am running another scan with ESET. It is so far clean; however something is really active in the file activity; read and written data. Getting spikes 10 to 25MB. I ran a volume check; it finished about 10 minutes ago. It came back clean. Didn't free up any space or report any errors. If I don't have a virus then what can it be? I have very few programs running at a time. Firefox, my security, and a few Windows programs are about it.

Sounds like something is being downloaded. I suggest you reboot into Windows Safe Mode with networking by tapping F8 at start up and selecting that choice.

Then see if the empty hard drive space still shrinks.

What exactly is my security? Take a look at the link below.

I may be reaching out into left field here but could the OP's page file be growing? I know when I leave mine set to system manage I have seen it get fairly big. Granted not the extent the OP is stating. Just a thought. My limited experience is showing through.

Page file is a percentage of the remaining free space. Once set it wouldn't normally grow. In this case it appears that a majority of the drive is being taken up by whatever.

In #6 above I linked to a removal tool for malware called my security engine, which may be on this computer.
