It is raining in Hangzhou today, and Shichao's mood is as chilly as the weather. But then I thought it wasn’t a big deal, so we reconciled at lightning speed. . . Then when she used my computer, she found that all the photos were gone, and Shichao was kicked out of the house. People cannot be generalized. Shichao really found a useful data recovery software when he was extremely angry. Without further ado, today I will show you a good data recovery software! If you want to recover files, you have to understand one thing: where do files go after they are deleted? First of all, we need to make one thing clear: after we delete files to the Recycle Bin, they are essentially just moved, because we can restore files from the Recycle Bin at any time. After the Recycle Bin is completely deleted, the problem becomes a bit tricky, but thankfully, the files are still there. At this point someone will ask: I can’t find the file, and you tell me it’s still there? This is where the file storage mechanism comes in. Our files are stored in the hard disk in binary format. If you imagine the hard disk as a blank piece of graph paper, the data are the 0s and 1s written on it. Having data alone is not enough, we also need to know where it comes from and where it goes, as well as what it is called, so that it can be managed easily. At this time, the system will create file nodes for the data, which is equivalent to classifying those scattered 0s and 1s. When we delete a file, we actually just delete the file node. Although the system defaults to that area being blank, the data is still there. Of course, if you are ruthless enough and use functions such as file shredder to delete, the system will fill that piece of data with random data, and at this time the data is likely to be irrecoverable. . . Data recovery software is like a skilled doctor who can dig out the underlying data that we cannot see but does exist, and then recover lost files by analyzing text headers and combining scanned underlying data. After trying many data recovery software, Shichao finally found a free and easy-to-use software for everyone - Recuva. Open Recuva and the system will provide a user-friendly wizard. Taking the picture that Shichao wants to find as an example, select the retrieval type and deletion path, and then leave it to the software and let fate take its course. Recuva can recover more than just data in your computer. You can also try to use it to recover files in USB drives, SD cards, or mobile hard drives. After searching for a period of time, the system will roughly divide the found files into three categories: excellent, poor, very poor and unrecoverable. Excellent files are of course recoverable, poor files are questionable, very poor files are basically unrecoverable, and if they are unrecoverable, you can only accept the situation with regret. . . In order to prevent users from wasting time, Recuva also provides a preview function. You can view the specific information of the file on the right side of the interface. If you delete a file and then rewrite it, the image will look like this after restoration... However, judging from the recovery results, the effect is still very good. Although some parts cannot be recovered, Shichao is already very satisfied with the results. There is too much content, please click on the enlarged image Next, restore it to the location you want to save in the lower right corner. Be sure not to save the file in the previous folder, otherwise it will reduce the probability of recovery! In addition to photos, Recuva is also very powerful in finding other files, whether it is documents or videos, it can recover part of them. Shichao even found a video from two years ago... If you don't find the file you need, you can also start a deep search. During the search process of more than an hour, the system will thoroughly scan your disk. But if the file you are looking for happens to be on the SSD, then it is most likely gone... Everyone must know that solid-state drives use flash memory as storage media, not disks. Flash memory cannot hold data like disks and make room for new files when they arrive. In order to ensure that users can write files at any time, the solid-state drive will issue a TRIM command after the file is deleted, and the deleted files will be completely cleaned up as garbage. The advantage of this is that it speeds up the writing speed, but the disadvantage is that you may lose that part of the data forever. . . So everyone should think twice before deleting files from a solid-state drive. If Shichao’s photos were stored in the solid-state drive, he might be gone now. . . During the time I used Recuva, it really helped me find a lot of things I had deleted. Although some of them could not be salvaged, most of them were restored well. Compared with the repair software on the market that costs hundreds of yuan, Recuva also gave Shichao a good experience on a free basis. But it is also a double-edged sword at times. After Shichao told his girlfriend about the recovery process, she quickly found photos of Shichao and his ex-girlfriend. I won’t say more, my friends. Shichao will kneel on the keyboard first… |
