• Format your hard disk, using the software for initializing it.
• Using the preinstalled recovery program, bring the hard disk back to
factory-ship state.
These operations, however, only change the file allocation of the data; they
do not delete the data itself. In other words, the data retrieval processing is
disabled under an operating system such as Windows. The data is still
there, even though it seems to be lost. Thus, it is sometimes possible to
read the data by use of special software for data recovery. There is a risk
that people of bad faith may read and misuse the critical data on hard
disks for unexpected purposes.
To prevent the leakage of data, it becomes very important that you take
responsibility for deleting all the data from the hard disk when you
dispose of, sell, or hand over your computer. You can destroy the data
physically by smashing the hard disk with a hammer, or magnetically by
means of strong magnetic power, thus making the data unreadable. But
we recommend that you make use of the software (payware) or service
(pay service) specifically developed for the purpose.
