How To Wipe Hard Drive

    View: 
Wiping a hard drive should be done periodically. This process helps maintain the speed of your computer. Fact is, even if you have deleted less than desirable programs from your computer, those programs still leave traces and footprints than can often slow down and affect the function of your computer. The Add and Remove feature of your computer is not fully equipped to fully remove traces of programs that you have deleted, chances are, there are still a few stragglers hanging around without you knowing it.



This is one of the reasons for problems with your computer like errors that you cannot explain the origin, glitches and even worse, crashes. Wiping a particular drive, oftentimes DRIVE C is useful when REINSTALLING the Operating system since it will make sure that any Virus or Worms are non existent prior to installation.

Erasing the data from your hard drive is also necessary if you will be selling your computer as a second hand product. If you are, you cannot leave any data that might compromise you. Some criminals can use the data left on your computer's hard drive to steal your identity.

Wiping your hard drive can be easy; it just takes up some time. Before you proceed with the overhaul of your computer, remember to store your important files in a folder or removable storage disk that you can access once the hard drive wipe is complete. After you have backed up your files go back and look through them once again. Remove those you do not like and make sure that you have the means to re-install those that you want to keep. A very important note is to save your emails. Some people proceed to wipe their hard drives forgetting to save their emails and end up loosing very important correspondence. So before you start with the wipe, make sure that you have stored all emails in a safe location.

Most people shy away from cleaning their hard drives because they think that it is too difficult. It is true, it may take time, but it is time well spent. You can either make it easier by performing the steps outlined in this article or you can have a professional do it for you if you are not confident enough. Another option is to avail of hard drive erasing software that come in the form of floppy disks, CDs and downloads. These products make erasing the contents of your hard drive much easier and quicker.

It may seem like a lot to do, but once you have successfully wiped your hard drive and installed new programs, it will be a like a breath of fresh air for both you and your computer. If you do not find the options presented helpful or applicable to you, here is one that may help. If you have the budget for it, just go ahead and buy yourself a new computer. Saves you time and energy, plus the new computer may look much cooler than the old one.
How To Wipe Hard Drive
When you delete a file from your hard disk, it may seem as if it is gone forever. In truth, however, this is not the case. The seemingly permanent process of file deletion actually leaves the file data still on the hard disk. When a file is deleted, it is simply marked ?deleted?, and the space that it occupies on the disk is accordingly marked ?ready for use?. Hence, it may be overwritten when more disk space is required, but this is by no means certain, unless the entire hard disk is filled with data.

Now, the actual data that make up the file is still on the hard disk, even after deletion. This makes it available for recovery, usually done using specially designed data recovery programs. MSDOS, in fact, has a built-in UNDELETE command which may recover recently deleted files.

The reason why file deletion is not as thorough as it can be is a simple one; resource management. Actually overwriting every bit of every file that is to be deleted will use more resources than would be practical, for everyday use. And in fact, this simple file deletion is usually sufficient for the basic user's needs.

However, security considerations might necessitate the complete erasure of a given hard disk or collection of hard disks. When reassigning hard disks, for instance, or switching computers around, confidential data might need to be deleted. To lessen the possibility that this data is recovered, a hard disk wipe may be performed.

When a hard disk wipe is performed, the entire area of the hard disk is actually overwritten with random data. This means that the data that used to be on the hard disk becomes much harder (practically impossible) to recover after such a process. Almost no traces of the previous data that used to be on the disk is left, making a hard disk wipe a secure improvement upon ordinary file deletion.

The metadata or information on the data that used to be on the hard disk is also wiped clean, since the entire space of the hard disk is overwritten. The randomness of this data used to overwrite depends on the algorithm used to generate it. Some hard disk wipe programs give users the choice to select the algorithm they want the program to use. However this is not as necessary for hard disk wipe programs as it is for file shredder programs, which wipe individual files. This is because when it is the entire hard disk that is wiped, the degree of randomness of the overwriting data is not anymore as important.

Performing a hard disk wipe is often as easy as clicking a few buttons in a specially designed hard disk wipe program. Some programs are set to run automatically when a CD containing the program is placed into the computer containing the hard disk to be wiped. This makes it easier to perform batch wipes on many computers at once, and makes the hard disk wipe a feasible security solution for multiple hard disks.
