Just installed new 320 GB HD and Vista Business & Office 2007 and my data etc.
"My" Computer shows:
1) 298 GB available, lost 22 GB to formatting, OK.
2) 168 GB free, meaning I've used-filled 130 GB already.
3) Only 3 file folders on C drive, Program Files has 2 GB, Users has 54 GB, and Windows has 7 GB, total used = 63 GB.
This means that (130-63) 67 GB has gone AWOL ! ! !
Anyone understand why or what's happening? I've done disk clean and that didn't help.
Just cleaned out old restore point files and that took my use down to 116 GB from 130 GB, still have 53 GB AWOL !
press the alt key
select tools/folder options
select show hidden files and folders
uncheck hide protected operating system files
Enter the root of your C:\
now look for folders that start with non alpha numeric characters like ~ @ # $ % ^ & * these are deletable. I don't know for a fact that this is the space your missing? If nothing is found in root then you will have to hunt and peck.
First I want to show why are you losing that 22 Gigs when formatting.
Hard disk companies say that the disks are 320 GB's but that's awfully wrong. Their disks are 320.000.000.000 bytes but we all know that it takes 1024 bytes to make a Megabyte, not 1000.
So, 320.000.000.000 divided by 1024 = 312.500.000 KBs. We already "lost" 8 gigs.
312.500.000 divided by 1024 = 305,175.78125 Megs. We are 15 GB down now.
Finally, 305.175,78125 divided by 1024 = 298,023223876953125 GBs. And that is how you actually lose that 22 Gigs. I would love to get a Hard Disk that says the correct size in the label but I don't think I'll see it happen.
Now, for your lost files. You are probable selecting all your files and doing Right click => Properties. The problem with this method is that those files that you don't have access (Other users files, files without permissions, etc) don't count for the size in the properties number. They DO count in the total size when you do properties to your HD of course.
So, if there are multiple users on your pc that may be the cause. If not, you may take ownership of every file and then look at the size again. I'm sure it will be similar to what you have marked as used space.
Sorry if I'm not clear enough, my english is not perfect.
