INTRODUCTION -The Misconception Of Deletion.
Deceit:"Think deleting a file makes it disappear forever?THINK AGAIN.
Most people assume that pressing "Delete" erases a file completely but the the fact is more complicated.
In reality,deleted files often stays on your device long after you think they're gone.
WHAT HAPPENS WHEN YOU PRESS DELETE?
_On windows and Mac, the deleted files goes to the recycle bin.
_Emptying the trash doesn't erase the data -it just erase its source from the system.
_The file still remains on the hard drive until new data over writes it.
THE SCIENCE OF DIGITAL DELETION
Computers store data in blocks or sectors on a hard drive.
when a file is deleted,the system marks it's space as "available",but the actual data stays there.
On traditional hard disk drives (HDDs),old data can remain for a long time.
On solid-state drive ( SSDs) deleted data may disappear faster due to the TIRM command, but recovery is still possible in some cases.
CAN DELETED FILES BE RECOVERED?
Yes! special software ( like Recuva, Easeus and forensic tools) can recover "Deleted " files.
Even after formatting a drive,some data can still be recovered.
This is why criminals/hackers can recover important data from old devices.
HOW TO TRULY ERASE A FILE.
1.Basic Deletion:Just removes the reference,but the data is still there.
2.Secure Deletion Methods: over write the file multiple times using software like ( cleaner,Eraser or DBAN ).
Factory reset with data wipe ( for phones and computers).
Physical destruction (For Highly sensitive data,shredding the hard drive is the safest option).
THE SECRETE DANGERS OF DIGITAL TRASH.
Privacy Risk: if you sell or give a way your old devices someone could recover your deleted files.
Data leaks: companies must properly erase sensitive customers data or risk leaks.
Environment Impact:Digital storage requires electricity,keeping un-required files stored on clouds servers consumes energy.
CONCLUSION
Recap "Deleting a file doesn't mean it gone . To truly remove/erase data,you need to overwrite it or destroy the storage devices".
