Dont worry everyone, 99% of you arent using spinning disc drives anymore...
This video belongs in 2005...

What about digital data such as on ssds?
2026-08-24 06:51

almost scary how we even managed to come up with this way of storing information.
regardless thx for the info, got go through a couple of step next time i say goodby to my pc.
trash it badly.
burn it
find some substance that mess up those layers.
bury it (better be sure....)
2026-08-24 06:40

So no stopping the world from ending
2026-08-24 06:23

I always get confused about what happens when I delete the data, how it is shown as empty, and how the data can be recovered. Thanks for a pretty good info
2026-08-24 04:39

Yea, I had to do that when my laptop crashed close to exam season. Does this kind of recovery also work for usb sticks though?
2026-08-24 04:36

Some people are getting scared ?
2026-08-24 03:50

Thanks?
2026-08-24 03:45

You'd be surprised to have effect with thermite is at permanently erasing data
2026-08-24 16:35

She called that GARBAGE art? ??
2026-08-24 14:45

Depends on the formatting type. A quick format wipes the file allocation table or FAT. A full format wipes the FAT and writes 0's on the entire disk.
2026-08-24 13:16

So it doesn't delete the destination instead it just deletes how to get there.
2026-08-24 12:28

lol yup.. i've recovered 10 year old data on SD cards i've formatted numerous times over years.. some files aren't fully recoverable but yeah, only way to permanently delete files is to physically destroy the memory.. or burn it
2026-08-24 10:10

That is why it is called the RECYCLE Bin. It's been in the name for over thirty years.
2026-08-24 09:51

So it doesn't deletes the data ,it simply ignores that data until it's full of space and needs that ignored space and then it alters the magnets
However, any information that once existed on internet can never be deleted, until any situation like dr.stone arrives where almost every human creations decompose
2026-08-25 04:35

You need a super powerful magnetic field to erase it or burn it lol
2026-08-25 00:04

If you want to really delete it, you need to overwrite it. Delete, then download something on it. In particle this probably means that you need to fill the whole drive to be sure.
2026-08-24 22:20

Genius move on the photographer's part.
2026-08-25 17:54

You mean… if the cops get ahold of my HDD… they’ll be able to recover all the…. Oh boy…
2026-08-25 14:33

H. Clinton…
2026-08-25 13:12

What an interesting story at the end I wasn’t expecting that
2026-08-26 08:46

Hopefully any proceeds went to the actual photographer instead of trolling the burglar
2026-08-26 08:44

So how does this work on a SSD then?
2026-08-26 08:22

If I recall, only DOS or windows editions had an undelete button or command. You basically, only if you did it before the file was overridden, could undelete a file.
Also im curious how this works on a SSD.
2026-08-26 06:32

A high powered magnet, thats gow you wipe the data. Hilary Clinton taught me this.
2026-08-26 05:37

looks robotic...
2026-08-26 05:37

Deleting just marks the space as available to override.
2026-08-26 05:01

That's why I fully format my discarded drives if possible, then physically destroys them before they go to the waste bin in order to make sure.
There's a reason why a quick format takes like 5 seconds to complete compared to a full format that can take up to 5 hours if it's a big drive.
2026-08-26 04:26

Easier way to think of it. A hard drive is like a wasp nest. Every chamber is a slot for information fragments. When a file is saved, its stored in these cells. The file is split into thousands of tiny pieces to make it faster to load. When you "delete" a file, it merely toggles a YES/NO setting to let the machine know all the cells that made up that file are available to be OVERWRITTEN. Everything still remains. The only way you know a file is 100% gone is by OVERWRITING those available cells already containing info. This is how they can solve crimes even with a few shreds of a damning document/photo/etc. I remember long ago in the early/mid 90s when the net was more or less a huge pile of unchecked forums loaded with illicit things (yeah, Ive stumbled on stuff I didnt want to), Id see these CDs that were supposed to help you eliminate digital data by loading your system to the brim with GARBAGE FILES which would overwrite everything but the main system files, then "delete" all the junk. The junk would remain but whatever it buried would be gone. Your system would be "flushed" and fully available for re-writing. (This is also what DEFRAGMENTATION is all about. As you write and re-write files to the same cells, things get MESSY, cells are scattered more and more, and the machine runs slower because of it. Defragging more or less repositions all the cells into a nice neat cluster instead of the jagged strip of lines you see at the start of said process.)
2026-08-26 03:52

What you have to do is a full format, not a quick one, theres also data scramble software that will format and scramble jobberish on every secor of your hdd
2026-08-26 02:06

The same thing (minus the burglary, just windows being shit) happened to my game footages as well
2026-08-26 00:33

A proper data recovery lab has black magic tools and tricks beyond a DIY software. One way involves reading the edge of the track for a trace of previous data. Sometimes you get lucky.
2026-08-26 00:07

Backup your data, people! If it's your life's work, maybe it's worth a little insurance. In this story, while leveraged by the theif, it's sadly a self-inflicted wound.
2026-08-25 23:59

I dont assume, I know that it just deletes the file directory and when the HDD is being used it just writes over it
2026-08-26 20:33

???
2026-08-26 20:15

But, it doesn’t make sense?? when I remove files on my system, my total storage percent decreases... So, If this is true, your removed files actually still inside in your disk?? Right? So.. once you wrote bytes on your disk, That’s impossible to remove it "totally"??? I still couldn't understand! Could someone help me to get the point? how my remain storage increased in that case?? ?
2026-08-26 17:58

How tf does someone come up with this? Lol
2026-08-26 15:47

I smoked a cigarette to this one
2026-08-26 11:54

In the mid 2000s police suspected a man had been to some very bad corners of the internet and had downloaded many illegal things while he was there.
According to one of the man's ex-gfs he had an entire hard drive filled with.... Lets call it... Pizza.
Normally it wouldn't be hard to get a search warrant to find the drive. But the ex was not found credible because according to her own testimony they had a messy breakup. The judge wasn't convinced that she wasn't just trying to get him back. So no warrant.
So she faked going back to him. Pretending to reconcile the relationship. Then she asked him if he had a HDD he didn't need anymore. He gave her an old formatted drive.
She took it to the cops and they found a mountain of pizza on it after they did forensic data recovery.
His lawyer would construct a defense stating that the ex had set him up. That the drive in question was never in his possession and she had lied to the police.
The man would be vindicated when it would come out at trial that the HDD contained recovered data that pointed to it being her drive, not his. Data she had tried to delete before filling it with pizza she had downloaded to set him up.
He was found not guilty.
2026-08-26 11:32

Does anybody believe in proper backup routines? Like the 3-2-1 system.
2026-08-26 10:47

It's not deleted forever but it is destroyed forever
2026-08-26 09:58

Common sense btw
2026-08-27 07:55

Microwaving or acid bath aka Killery bath?
2026-08-27 05:19

I know how to destroy old drives... properly. Done deal.
2026-08-27 14:38

I believe I got around this by writing 0x00 or even 0x71 all over the file in c++ programs. Plus bypassing optimization in case it helps. 0x71 appears as a million letter q's if you open it as text.
2026-08-27 13:08

I may be wrong but if you pull out the drive and pass a strong magnet over it would delete it. If I am please let me know
2026-08-27 12:12

This was so interesting!
2026-08-27 12:08

This is why they use magnets to delete information during police raids
2026-08-27 11:31

To delete it for sure take that disc out and melt it
2026-08-27 11:23

This explanation confused me even more.
2026-08-27 10:36

We used to drill a couple holes on old harddrives and drop them in buckets with salt water in order to wipe them for good.
2026-08-28 00:50

Its easier to smash to the hard drives platters to actually "delete" data
2026-08-28 00:47

Brilliant idea! ?
2026-08-27 22:42

laughs in SSD*

2026-08-28 14:49

I put mine in the microwave. Learned that from Thomas Anderson.
2026-08-28 13:39

I do not ever think it's deleted
2026-08-28 11:48

So you can play doom on a PC
that doesn't even have doom anymore?
2026-08-29 04:11

You can delete permanently the files if you want tho. There's (or there was) a tool called 0fill wich fills all sectors with "0". Idk how it's been done for the last 20 years or so, but I've been there, did that.
2026-08-29 02:07

TLDW: Basically "deleting" an item just marks the item to be overwritten. The "storage space" of an item is more about how much storage is locked or unlocked for overwriting purposes
2026-08-28 23:17

But this makes no sense. This way, the storage should run out even when I delete files again.
2026-08-28 21:49

Welcome NAND flash
2026-08-29 16:47

Literally everything I've seen these days including pocket PCs on temu use SSDs....so modern so relevant.
2026-08-29 13:43

This is only true with with spinning hard drives most hard drives or ssds now it does work similar but you can't really recover it in the same way as a spinning disk and formatting a hard drive does actually write ones and zeros two the entire hard drive deleting the data formatting does actually destroy the data so this is 100% wrong formatting does destroy the data deleting it when you're in an operating system does not
2026-08-29 10:09

Same with SSD, because the hardware gets damaged a bit every time you write something on it, so it just rewrites everything on the "deleted" data instead of giving a reset, theoretically doubling the lifespan
2026-08-30 00:18

Back in the day, I was able to pull data off my computers that I accidentally deleted. I forget the program but being able to find photos that way was a lifesaver.
2026-08-30 17:22

I really wasted my time watching and listening to this shit! ??
2026-08-30 23:19

Got to know about this in a Vsauce video first. Pretty cool information about deleted files and how hard drives store data.
