Why not to sell you HDD or SSD with your computer

[Bl4ckCyb3rEnigm4]

I know anyone want to make some money from an old computer, sometime gettting less money isn't the worst thing. Your HDD or SSD preserve a lot of your important data like your family trip images or all your work files. When you delete a file, the file is showed how "deleted" but instead is still on the disk. The file will be still on the disk until you don't overwrite it with another file, for that reason there are some tools that are made to overwrite and make impossible to recover a deleted file from the disk, such tools are called "anti-forensics tools". You will think that a normal format of the volume will make all the files disappear: Wrong. The files will be still here. For that reason all the biggest companies over the world don't send all the old computers parts to the dump, instead the disks will be sent to a company that will physically destroy them, because on companies computers there are also login credentials and sensitive data. So the next time you sell a computer make sure to remove the disk and install a brand new one, because your data are worth more then few dollars.
