When you erase a document or other file from your computer, it doesn’t really leave – even after you’ve wiped the Recycle Bin. The bits stay composed on the drive until some other action rewrites over them. Unfortunately if you don’t take the right steps, documents are still there for the individuals who need and know how to get their hands on them and this can spell danger.
If we assume that you need to really and safely erase something, or even the substance of a whole drive, a simple delete key won’t do it. You need a programme to get rid of the files completely. This comes in really handy if, for example, you need to sell the computer on and want to make sure there’s nothing on there that could cause problems in the future.
Software that can permanently wipe sensitive data is available, and doesn’t cost the earth, such as Super Eraser. This software works not only on your computer’s inbuilt hard drive but can help with other devices, it can wipe stuff from your tablet, SD card or other mobile storage, or even an external hard drive.
There is a limited trial version available for you to ‘test drive’ so to speak, but the most powerful versions do come at a cost. The benefits of doing so are clear, and this is super easy to use as well so you don’t need to be a computer whizz to use it, even the less tech savvy can safely erase their files.
