How to Properly Wipe Any Hard Drive – FREE TOOLS
Are you looking to sell an old computer and want to wipe the hard drive before selling it? Whatever your reason, there are many programs that can help you not only erase the data on a hard drive, but also wipe it in such a way that it can never be recovered. If you have a lot of sensitive information, it is highly recommended that you securely wipe your hard drive.
A secure wipe essentially performs a low-level format, so the entire drive is overwritten with zeros. Other software writes junk data multiple times over the drive, so there is no trace of what was there before. Either way, no one will be able to retrieve the original data from the hard drive, because it is completely gone.
In this post I will list five fairly popular programs that you can use to really wipe a hard drive. There are so many good free programs out there, there is really no need to spend money on something like wiping a hard drive. You will get pretty much the same results with freeware.
