It can be an​ advocacy but usually,​ companies that dispose old computers when they buy new units often donate the​ equipments to​ institutions and to​ some people who need personal computers .​
This is​ a​ widely acceptable practice .​
But are you ready to​ give much more than the​ worth of​ the​ personal computer you are donating? You might not be fully aware of​ it​ but when you are giving your old personal computer to​ other people,​ you are also giving the​ recipient the​ opportunity to​ access your old files and information saved previously on​ the​ hard disk.
Even if​ you have deleted the​ files in​ the​ Windows operating system and in​ the​ Recycle Bin,​ there would always be traces of​ the​ deleted file somewhere within the​ hard drive of​ the​ computer .​
The simple process of​ deletion would only remove the​ shortcuts to​ the​ files .​
In actuality,​ the​ files are still there,​ though you could hardly trace them .​
But imagine if​ in​ the​ long process of​ donating,​ the​ personal computer goes to​ the​ possession of​ an​ expert who could be able to​ restore and retrieve the​ deleted files .​
There are many recovery and restoration software available in​ the​ market that could facilitate instant retrieval of​ deleted files.
Will you be willing to​ afford to​ lose sensitive information like trade secrets,​ personal information,​ confidential data,​ bank and credit account numbers and contact details of​ clients?

Thus,​ you can rest assured that no data or​ file would ever remain in​ the​ computer memory for life .​
To put it​ simply,​ it​ is​ impossible to​ retrieve data that have already been overwritten .​
The process is​ irreversible.
