When you "erase data", you generally do one or more of the following:
Discard data in the "Recycle Bin".

"Delete" data.

Erase data using the "Empty Recycle Bin" command.

Perform initialization (formatting) of the hard disk using software utilities.

Recover the factory defaults using a recovery CD.

The above operations only change the file management information of data recorded
on the hard disk; actually the data is just blocked from view.
That is, although the data appears to have been erased, it was just made unavailable
under an operating system such as Windows. The actual data remains on the hard
disk and may be read using special data recovery software. Consequently, important
data on the hard disk of the system equipment can be read and used for unexpected
applications by malicious people.
To avoid unauthorized access to important data on the hard disk when disposing of or
transferring the system equipment, it is extremely important for you to erase all data
recorded on the hard disk at your own risk. When you erase the data, we recommend
that you purchase and use a dedicated software or service, or corrupt the data on the
hard disk physically or magnetically using a hammer or strong magnet to make it
unreadable.
Transferring the system equipment without deleting software on the hard disk
(operating system, applications, etc.) may be against software licensing agreements.
Check your software licensing agreements carefully.
