We will cover this further soon, remind me to link here.

Overview of Hard Drive Technology


A Hard Disk Drive (HDD) is a fixed storage device that stores data magnetically. The data files are saved on the surface of rotating magnetic platters enclosed within the drive case. During retrieval and writing of data, the hard drive converts the magnetic platter surface into binary code. When you save documents, photos, etc. on your drive, they are stored in rows of zeros and ones. Hard Drive SSD and ATA Explained | Hard Drive Prices

When you delete a file, those ones and zeros remain unchanged until they are entirely overwritten with new ones. What of drive formatting? The same case applies. The data is not entirely wiped out. Magnetic drives are mentioned here but faster, lighter SSD Hard drives are the new default storage so if you want to have read it is covered here.


How to Wipe Your Laptop Drive



Wiping a hard drive is not the same as formatting the drive or deleting data. Deleting data hides it from an instant view or search up. This does not permanently free the data, as a data recovery software can retrieve the files. On the same scale, formatting does not erase the data. It is akin to deleting sections of a book without rearranging the actual chapters. Interesting, right?

What is the Magic Behind Drive Wiping?


It can be confusing to learn how drive wiping works, but deletion and formatting do not permanently clear your drive. As highlighted above, HDD/SSD stores data in binary form. For a total overhaul of your drive, you need to get rid of the existing binary data. This means replacing the real zeros and ones with new ones; new data. Replacing and overwriting the binary data of a file by new data renders it unrecoverable forever.
