There are quite a few people who are looking to buy IT devices before the new semester, whatever their laptop, tablet or mobile phone. So what are you going to do with the original thing? Carrot market? trash can? You don’t feel good? So I prepared! How to properly handle IT devices! Normally we erase this data here very hard, very hard, very hard before we process our IT devices, but wait! If you just delete it as before and sell or throw away your device, it could be really bad. Why? I did a simple experiment! I gave the interns a USB and asked me to save a picture and a text file that wrote what I wanted to say to me, and then delete it on my own. After that, I used a recovery program that is easily available on the Internet to restore it. What's the result? Oh (recovery) I think I'll be scared, I think I'll distrust the world Evil! How did you do it? is this right! How did you do this? I have it all, because even if the user presses the delete key, presses the delete button, or empty the trash, this does not actually erase the data itself. It takes a lot? So, in the normal case, the data is left and only the route to which the data can be found is erased. To compare this, in a hotel full of guests, the guest did not actually let the guests out, but the list of stays. When you open a door, there are still guests in it. So, if you simply press the delete button like this, your information will be recovered from someone's hand, and all sorts of problems can arise here. Actually, the printer multifunction device we use at the company is also opened in it. If you look at it, there is a hard disk in it. All the documents you print are recorded on the hard disk inside the multifunction device and then printed out. So if you just throw away the printer without thinking, you can restore all the documents that were printed from the hard disk. So what should I do? here! There are different methods depending on whether you are erasing information on an SSD or a hard disk or USB. You don't know if what I have is an SSD or hard drive? In Windows, go to My PC, right-click the drive, click the Properties button, and select the Hardware tab. If you search for this name by Google, you can check whether the disk you have is an SSD or a hard disk. From now on! I will explain how to delete the hard disk or USB, which is a bit complicated. Now, in the case of a hard disk or USB, you can erase the data itself, not just erase the data path, and then overwrite it with other data. The more guests come and go, the more the traces of existing guests will disappear. Anyway, the following programs take over to completely remove data from the real world and overwrite it multiple times. 6. It's a program called 2. You just need to download the program, install it, and touch the settings. Don't think it's difficult because it's in English. Just do this. It's a hard disk permanent deletion method recommended by the US Department of Defense. Save the settings with this, format the drive once, and press this button. Oh, that's important here. It takes a few hours is the default, but it can be a few days. If you do it during the Lunar New Year holidays, you will feel more comfortable. So, how do you erase the SSD? It’s much simpler. In fact, most SSDs have built-in functions that automatically delete accumulated data after a certain period of time. At the level of common sense, just start the computer and proceed with Properties-Tools-Drive optimization! Data on SSD is almost impossible to recover. There's another problem here. It's a broken laptop or console that doesn't turn on properly, right? In this case, you have to unavoidably remove the disk from the laptop or the main body. After disconnecting, there are two options. One is to connect this disk to a PC and perform the previous deletion operation, and the other is to utilize this property physical hard disk. If the disk or SSD is too old and you just want to throw it away without thinking of selling it, break it physically. You can't roughly break it. In the case of hard disks, remove the external material and chip until all the shiny disks called'platers' are split apart After the electronic products are processed like this, put them in a collection box or put them in a transparent bag and throw them away on the day of recycling, so you can say goodbye to old devices. No. Actually, there is one more important product than this, this friend's smartphone! Knowing all of me! How to let this friend leave where all of me is saved! I'll explain it next week. I feel good, thinking about the head of someone who hates this about
