  • Deleted files can be overwritten by new files
  • Avoid using your storage device
  • Even booting your PC places deleted files at risk

Don't save any further files to the storage device.

Lost files or deleted files are occupying an area on the storage device that can be allocated to new files. When a new file is created it will overwrite a portion of that available area. That portion may contain the pre-existing data you wish to recover.

In the case of hard disk drives, just running an operating system will write data to the drive even if the user doesn't.

For example large files commonly known as 'swap files' or 'page files' are created to help manage the use of system memory. These files can range in size up to twice the size of the system memory.

It is also important to protect your devices from physical trauma, and unsafe environments. You should avoid bumping or dropping hard drives, bringing them into contact with electrical or magnetic fields, heat, moisture etc. The same applies to all electronic storage devices.

CDs and DVDs can be damaged by permanent markers not specifically made for that purpose. Likewise pens and other pointed writing implements can damage the data layer lying close under the surface of a disc.
