Do you know how Data Wipe works for PC?

Have you ever wondered if the data you delete from your computer has been completely removed from your operating system? By pressing the delete key or emptying the recycle bin, we do not completely get rid of those files that we want to eradicate completely.

In the event that we want to sell or get rid of that old PC or hard drive, we must remember that there may still be sensitive data stored on the device. Many believe that by deleting them or formatting the disk they have been eliminated, but it is better to check again.

Although it is possible to delete files with the keyboard without going through the recycle bin, using the Shift + Del (Del) key combination, it is also true that, with the help of special programs, these files can be rescued again without problems.

This is because Windows only wipes the index, but not the data, which remains intact on the hard drive. In other words, the operating system only deletes certain areas of the disk but does not overwrite them. If you want to delete these files without the possibility of recovering them, you have to use complicated Windows resources or simpler erasure tools and without cost.

For example, you can completely and definitively do the Data Wipe from the hard disk through the "Execute" tool of the Start button, using the "cipher" command, which deletes the data that is ordered, which overwrites the place it occupied in the PC memory. However, this tool is not used to perform the Data Wipe on entire hard drive, as its use is complicated and slow.

 

Another safe way to delete documents is through the Secure Wiper program, a very extensive free tool that does not require much experience to use, and that repeatedly overwrites deleted data. To fulfill its task, this software, which has a graphical interface, conforms to international standards that require that deleted data cannot be recovered again.

 

If you want to remove the entire contents of the hard drive, you can start the computer from a "live CD" - an operating system stored on a CD - such as the free Ultimate Boot CD, and attack the hard drive through the Linux system.

 

To delete all the data you can use the CopyWipe tool, downloadable from Ultimate CD through the path "HDD \ Disk Wiping". After starting the program, you choose the hard disk you want to wipe and determine how many times you want to overwrite each sector with zeros.

 

Another reliable alternative is the program Darik's Boot and Nuke, also the Ultimate CD. The Darik procedure, in any case, can last several hours, for which you have to take your time. In the Parted Magic partition tool, which is also on the disk, there is also an erasure program locatable as "System Tools \ Wipe Disk".

The deletion of a solid SSD can be done by freeware tool SSD Toolbox with Intel. In its current version 3, the "Secure Data Wiping" function can also reliably wipe data from an SSD disk, although some users have complained about problems with this software on certain SSD disks.

 

Another useful tool is SDelete, one of those included among Microsoft's Sysinternals helper programs. These same programs can be used to perform Data Wipe on  stored on portable memory such as SD cards or USB sticks, as long as the NTFS file system is in use. In any case, the Tool Wiper is enough to wipe these small devices, another tool that is obtained free of charge.

 

But if you want to recover photos, images, texts and other files deleted by mistake, you can use the PhotoRec tool, also free, which is capable of restoring files that Windows itself is unable to repair or recover. The program does not need to be installed and can be started directly, although its use is not simple, despite the fact that step-by-step instructions for use are found on its download page.
