Recovery method for data loss in computer systems

I. About Hard Disk Data Briefly Each user's hard disk stores important data. The hard disk is a relatively fragile component in the PC hardware. A small misoperation: the host suddenly loses power, the hard disk crashes during normal operation, and the virus is disinfected. Misoperation of software to delete normal files, accidentally delete mistakes, can be the main culprit affecting the security of hard disk data, and even the health of hard drives. Today we are going to talk about the recovery software after the hard disk data is lost. The protagonist is ——Recuva. Maybe, the data loss "nightmare" has not been entangled with you, but it is also necessary to be prepared, no one can guarantee and expect tomorrow. Second, Recuva fool-like data recovery Recuva is a file recovery tool compatible with all Windows platforms, users can use for free. In order to facilitate the use of more people, I recommend to everyone is the Chinese version of the library, in addition to the traditional native interface advantages, this version also revised the official version of the Chinese text display size, font small problems. Note to users: This Chinese version contains third-party plug-ins, users can choose to install according to their needs, users who do not understand my meaning of this paragraph do not install plug-ins! Recuva recovery can support formats of FAT12, FAT16, FAT32, NTFS. Of course, before data recovery, Recuva includes a system information detection function that allows users to further understand the status of the computer (Figure 1). Ok, let's simulate the recovery of the user's deleted data …… the successful recovery chance of the hard disk is that the original data location is not covered, it is not impossible to recover the hard disk data that is formatted. As shown in (Figure 3), the scanned file generally has three states, and the green light is “good state”, indicating that the file has not been covered by the new cluster, and the success rate of recovery is relatively large. The yellow light is not ideal, indicating that the deletion of the file may have been covered by the new cluster, and the recovery probability is not large. The red light is the worst state, and the basic recovery is hopeless. Each file scanned can also present a specific path and modification time. Recuva can not only recover the data of the hard disk, but also recover the data of the flash disk and the memory card, and the platform is also widely used. Third, to the users' suggestions Now the software may be useless to you, but the software itself is less than 2MB, free to use, storage without any difficulties, everyone should be prepared to prevent accidents. Regarding the recovery efficiency of files, according to the experience of software authors, the more messy disk file tree, it is more difficult to have more disk fragment partition recovery files, which is also the kind of recovery data software owned by the software. Free time to sort out disk fragmentation
