Data deleted using the keyboard Ctrl + Alt or after formatting a hard disk can be retrieved by some specialized data recovery software.
That is why it is necessary to use software such as Hard Drive Eraser to permanently clean out the sensitive data from your hard drive. This program uses an advanced and secure algorithm to delete the volume and the disk partitions so that deleted data are protected from any recovery software. To do this, simply select the drive to be erase, the file system (NTFS, FAT32, FAT), and click the "start" button.
