Deleting Data from the Hard Disk

About Deleting Data from the Hard Disk
Data can be deleted from the computer's hard disk.
Data written to the hard disk can be removed using the [Recycle Bin] or by
formatting the computer to the original state.
Selecting this menu will remove hard disk data that cannot be removed by hard disk
formatting of operation system standard, and the removed data will not be easily
recovered with recovery tools. Format the hard disk before transferring or disposing
of the computer.
Before deleting the hard disk data, return the BIOS Setup Utility setting to the factory
setting values.
Data can be deleted from the computer in the following 3 ways.
• Simple mode (1 time erasure)
Overwrites "00" data entirely from the hard disk.
• NSA-introduced mode (3 times erasure)
Deletes data from the hard disk in a method compliant to the U.S. Department of
Defense NSA Standard. The data is deleted effectively by writing random data 1,
then random data 2, then "00" data 3 times in order and then deleting it 3 times.
However, since the data is written 3 times, it takes 3 times longer than simple
mode for deletion to be completed.
18
• DoD-introduced mode (3 times erasure + Verify)
Deletes data from the hard disk in a method compliant to the U.S. Department of
Defense Standard. "00", "FF", and "random value" is written in order, and verifies
that the final random data is written correctly. Effective deletion is performed by
deleting 3 times. However, since the data is written and verified 3 times, it takes 4
times or longer than when in simple mode.
By using this method it is not guaranteed that the data cannot be completely
recovered.
