-하드디스크 폐기 요청이 들어와서 디스크 표면을 깔로 긁고 망치로 깼습니다.
I want to throw away my old computer, but I'm worried about the old data stored on the computer's hard disk, so I've been asked to physically break it by opening the lid of the hard disk instead of "initializing, formatting, and overwriting." As shown in the video below, if you have the equipment, you can put it in a shredder and dispose of it quickly, but there's no way there's this equipment in the local computer store, and I opened a hard disk and damaged the disk surface with a cutter knife. Can I restore a scratch-only hard disk like this? I didn't actually try to reactivate it. I'm curious as I'm writing. I heard it's very difficult. (I know it's almost impossible.)

Samsung 80 giga hard disk. It's a hard disk that's well over 10 years old. 15 years? I don't know if you've tried to separate it from your house, but there's no circuit board on the back.
The internal appearance of Samsung 80GB hard disk. The data was damaged by turning it with a cutter knife so that it could not be recovered.
Seagate 320 gigabytes is a hard disk. It looks like a product around 2011. I don't think there was a tool to disassemble directly because it was fastened with a star-shaped screw.
The screws that are stuck around the hard disk are easy to remove because they are easy to see. There's a screw stuck in the middle of the sticker, so you have to find it well and remove it to open the lid. If you just open it, it won't open well. If it's forced to open, the lid may bend, but it could hurt your finger, so if possible, it'd be good to remove the screws under the sticker and open it normally.
As I took it apart, I found 120 units of SSD. I told you not to dispose of SSDs because they are still available, but to put them in an external hard case and use them temporarily if your computer breaks down.
You decided to use 120GB of SSD again without breaking it.
A total of 4 hard disks were scratched on the surface with a knife to make scratches. The laptop IDE hard disk is the product with the least scarring surface, so I removed the disk and broke it with a hammer.
I think 500 Toshiba products are in good condition, but it's a waste to destroy them and make them obsolete. If you're using an existing computer, I don't think it's a bad idea to connect it with a sub and use it as a backup space for drives D and E. He didn't have the will to reuse it and wanted to throw it away no matter what, so he saw it next to me and threw it away together. If you bring this much when other customers are waiting, it may take some time to dispose of it, so it's hard to dispose of it immediately. If you don't have any customers waiting, you can watch it together and show them what you've done.
The laptop hard disk is almost broken like glass, so I put it in a plastic bag and hit it with a hammer to break it. The disc powder splattered out of the bag. I think it would have been nice to wear gloves and protective glasses, wrap them in A4 paper and CD bags, seal them in bags and break them. I only wore glasses to protect my eyes, but I just picked up the hard disk powder that was damaged and put it back in the bag, but I got a fine disk glass powder on my finger. If it gets stuck in my skin, I thought it would be hard to remove it, so I washed it right away with running water.
It's very weak. I hit it with a hammer once, but it broke into two sheets at once. I picked it up with my hands because there was debris splashing on the street, fine glass? The powder is on my hands.

Physical Fault Recovery Methodology for Hard Disks
In this paper, we want to analyze the technology gained from the manufacturers' know-how and the many experiences gained from the repair company in terms of compatible models for each type of hard disk and the measures and repair methods according to symptoms for recovery. However, even if you try the same thing in the paper, there is not much chance of success for inexperienced users. You will need to be more careful in diagnosing and dealing with a failed hard disk and putting it into practice after enough practice. Analysis was attempted by visual inspection, sound, frequency by symptom, and this result can be valuable in restoring data from valuable evidence...

I think it's a site where scientific papers are collected, but there's a lot of interesting content in the paper.
If you're interested in science, I think you'll search for it in the search box.
I searched for "SSD Recovery," and there are many related papers.
