How To Erase Data on a Hard Drive 

Thank you.

Magnets haven't worked since the 90s. The magnetic force required to corrupt the data on a hard drive is basically equivalent to a quasar.

You would need a USB. Both of these methods completely destroy everything on the drive. Including the OS.

@@CyberCPU Thanks for letting me know. Don't have a USB at hand or a copy of the OS. Great vid, got yourself a new sub

I recommend unplugging any drive you don't want to wipe.

@@CyberCPU alright thanks, i wasnt sure if the pc needed it to get past the post screen but i forgot were booting from the usb stick

Yes, should. Any x86 system. It will not work on the newest Arm mac's but it will on the older ones.

A strong magnet will not get everything, you really need a computer that you can run DBAN on.

if you mean the factory reset that you can do through the defualt setting apps on windows, the answer is no. People can still recover your data. What this guy is doing in this video is: 1. wiping your data, including the OS 2. writing random data on your harddrive. these two steps corrupts and destory any data that was saved on the harddrive. Please note that if you delete a file then the file is still on the harddrive, that's why it can be recovered. But if you save new data (just like he is doing in this video) if u save new data, then the old data will be wiped out or atleast corrupted.

Here we are a year later, and nobody has answered you, so here goes. The only thing on a PC that stores data is an HDD or SSD. If you removed them, then you have successfully left nothing on that PC for anyone to get. The RAM (memory) only holds data as long as the PC has power. Nothing else in the PC has the capability to store your data.

Unless you lowlevel format a hard drive, or use the secure wipe option in Mac OS X to do a one pass wipe by writing zeros to the drive you are not going to delete all your data permanently.

I agree, it works great and is easier to use.

Sudo commands to random write 3-5x and it's pretty much garunteed no one is reading that hdd

It's one option I cover. Not my favorite though.

lmfao

Instructions unclear, my house is on fire.

@@TheHellKnight Get out and call 911. Oh wait, "1 hour ago". RIP.

Untrue. I worked for a computer repair company and we regularly had customers (particularly government and elderly) who would request physical destruction of their hard drives. Also, even with as advanced as cyberforensics is these days, once a hard drives discs are destroyed, there is absolutely no way even the most committed tweaker would be able to piece and bond it back together. While the data may still be stored on the fractures the disk has to be whole in order to read.
