I am running 64 bit Vista on a fairly new HP. Something is happening with the storage on my computer. I have a 1 Tb hard-drive, and I am suddenly losing storage capacity at a rapid rate. Several days ago I discovered I was just about out of storage...totally shocked, but ashamed to say I had never really checked it recently. So I freed up some space--only to watch it go away each and every day, and this is without downloading anything! Today I ran a program to tell me what were the biggest parts of my storage, and photos and videos were the biggest culprits. I took alot of those files today and put them on an external hard-drive freeing up 250 gb. At least that is what it showed 3 hours ago....now, it is suddenly showing only 184 gb! So in the past 3 hours I lost all that storage.....I've run several different virus scans and nothing shows up....spy-bot, malware, and McAfee programs. My hard drive checks out okay too in every test I run....I don't know what to do at this point.
