How And Why To Wipe Disk Drives

Comments Off on How And Why To Wipe Disk Drives 22 September 2011

Nowadays, computers seem to be everywhere. They have truly revolutionized almost every aspect of modern society, by performing certain tasks much faster and much more efficiently. Because of their great effectiveness and inherent versatility, computers have been adapted for use almost everywhere conceivable. Offices, schools, and homes have all found their own uses for computers.

These irritating programs can interfere with your computer every time you jump online. Adware is more or less harmless when settled onto your computer by itself. Mostly it simply generates a lot of spam (unsolicited and unwanted email) for products that bring advertising directly to your email. Adware can also produce “popup” ads on your computer.

Spyware, however, is much more threatening and dangerous to your computer. Spyware not only floods you with advertisements, but it also accesses information on your computer and delivers it to other companies and potentially dangerous people. Additionally, spyware can change your entire computer through PC configurations which open you up to a world of trouble. Spyware is utilized by unscrupulous people as one of the main means of identity theft because it fishes information from your computer and can “learn” about almost anything you do on the Internet, then report back to the originator.

There are numerous methods for ridding your computer of spyware, but the most effective is learning to avoid it in the first place. You can begin this process by adjusting your computer settings appropriately. Depending on your operating system, you may need to do some informal reading of your system’s help files. You should find your Internet connectivity options and then look for a tab that refers to the security of your computer system. You should always adjust this to at least Medium security, or Medium-High. If you change it to High security, that setting might actually prevent you from accessing web sites that you need; so Medium is normally recommended.

In fact, there exist utilities to do just that: recover deleted data, thought to be lost. While this may be a good capability to have, sometimes data just needs to vanish, without any trace. For instance, when selling or transferring a computer, deleting any and all personal or confidential information might become necessary.

Physically destroying the hard disk drive or otherwise rendering it unusable is of course an option, but is not always practical. This is especially true when only a particular file needs to be deleted, and not the entire hard disk.
