Removing Files from Hard Drive
"My computer is 5 years old and it freezes up and shuts down on me at times. So I am considering buying a new one. How do I get rid of any files on it before I donate it to a school?"
Since you asked this question, you probably already understand the fact that simply deleting files on your hard drive doesn't actually remove them permanently...

When you tell your computer to delete a file, the operating system just removes a pointer from the file system, so the file can no longer be found on the disk. That physical space becomes available for other files, but it may not ever be over-written.
There are ways to recover files (or portions of them) from a disk once they have been deleted. So if you are considering donating your used computer to charity, you should take some steps to make sure that any personal information is truly expunged from the disk. Here's what I recommend:
If that solution doesn't satisfy you, there are two other options you can try:

The Ultimate Boot CD is a freely available utility CD that includes four different tools for wiping drives.

If your data isn't worth a huge amount of money, using any of those utilities will be sufficient to ensure your files are unrecoverable. Facilities will millions of dollars of special equipment could likely still read the data though, or at least portions of it. If your data is worth *that* much, do as the Pentagon reportedly does - shred the drive into a powder, then burn the powder in an incinerator. :)
Blowing it into pieces with a sufficiently large caliber gun can be a good time too. :)

hi bob when i download software like norton and i do not want it any more when i del it ,is it still on my hard drive i got nod32 now when i scan it showing norton still there wot can i do plz help
EDITOR'S NOTE: Wow... did you lose your Shift and "." keys? Anyway, my advice is do nothing and ignore it. I tried to remove the remnants of Norton from a machine once (after uninstalling) and it fouled it up forever. Had to reinstall the operating system. Norton gets its hooks in deep, won't let go, and that's why I don't recommend it.

I am trying to remove the contiguous files that are not being removed, how would I do that?
EDITOR'S NOTE: Contiguous files are GOOD. Fragmented ones are bad. What are you trying to accomplish?

I have a pc that the power supply went out on it. I got a new pc and wanted to remove the Hard Drive from the old and retrieve information from it, wifes cooking recipes, some addresses, photo's is there any way to do this?
EDITOR'S NOTE: Sure... the easiest way is to remove the old drive, and attach it to the new computer with an external USB drive kit. You could also install it in an empty drive bay inside the new computer, but then you have to fiddle more with the innards of the computer. You can find the kits at Radio Shack and other places, and they are very easy to use.

If you want to completely get rid of Norton, you have to use the Norton Removal Tool found on their website.
