The new O&O Defrag 29: Maximum performance for your PC – now with an integrated Startup Manager! Delete data – but please do it securely!
Before you sell a storage volume, pass it on to someone else or destroy it you must delete all confidential files and sensitive information to protect your privacy.
Deleting files or documents “normally” on a Windows operating system simply moves those files to the recycle bin to start with. These files only disappear from view when the recycle bin is full or the user proactively empties it. In truth the files are still on the computer drive – only the references to them in the file system index have actually been removed. As a result the files you think are deleted are actually still on the disk or drive and can easily be recovered with the best file recovery software, such as O&O DiskRecovery. Even formatting a hard disk is not enough to securely delete confidential data.
Files and documents on intact hard disks can be securely deleted by O&O SafeErase so that they can never be recovered. This is done by writing over the data either once or several times. There are numerous deletion methods available including the methods recommended by the US Department of Defense and from the German IT security authority, the Bundesamt für Sicherheit in der Informationstechnik (BSI), which offer the very maximum in data security.
With todays hard disk sizes it is normally sufficient to simply overwrite the data once, whereas with older disks with a capacity of 120GB the data should be overwritten 7 times in view of the lower storage density.
Recommendation:
You must delete your hard disks and SSDs permanently before you sell or pass them on! It is the only way you can protect your privacy and prevent identity theft!
