Some things on the computer are accidentally deleted, and the recycle bin is empty. What can we do to recover these file data? Now I share with you the basic knowledge of computer file data recovery. Let's have a look!
Users who often use computers should be very familiar with the recycle bin. Files we delete, such as photos, videos, documents, folders, etc., will be put into the recycle bin by the system. When developing the operating system, Microsoft did not name the "Recycle Bin" as "shredder" or "garbage bin" because the files in the recycle bin can be easily restored as long as the recycle bin is not empty. We often delete files by mistake or change our mind to find the deleted files. To retrieve the wrongly deleted files, we first thought of the recycle bin, but if the recycle bin is empty or the files in the recycle bin are deleted, how to recover the deleted files?
Happily, after the recycle bin was emptied, the data did not completely disappear from the hard disk! The operating system just marks the disk space occupied by deleting files as "free" to store new files. Therefore, before the new file occupies the area marked as "free", the deleted file can be recovered through certain technical means. Professional data recovery software is required to recover the files deleted in the recycle bin. The data recovery wizard can provide professional deleted file recovery function. As long as the files are not overwritten, the data recovery wizard can effectively and completely recover the files. In order to get the best data recovery effect, users should stop all other operations after discovering data loss, and immediately install the data recovery wizard software for file recovery.
During data recovery, it should be noted that the data recovery software cannot be installed in the partition where the data needs to be recovered, that is, the partition where the data is lost should avoid writing as much as possible. The data recovery wizard operation is very intuitive. Users can complete the data recovery operation according to the tips of the software wizard. In the recovery process, if they encounter problems, users can contact the software customer service in time to obtain technical support in time and recover the files deleted in the recycle bin as soon as possible.
As we all know, the operating system will slow down if it is used for a long time, because the software installed in the system, redundant registry values, temporary data, garbage, etc. will affect the running speed of the operating system. In addition, the operating system may be attacked by viruses, and sometimes the operating system will crash for no reason... After the system has problems, the most effective solution is to restore the system or reinstall the system. According to statistics, only a few users will have a backup of the system, while most users choose to reinstall the system after the system goes wrong.
Reinstalling the system will involve the system disk before formatting, and users often lose important files saved in the system partition. For example, many users like to save files on the desktop. In this way, after reinstalling the system, the files will be formatted. How to restore the data of reinstallation system is a problem that many computer users pay attention to and need to be solved urgently. So how to retrieve the data lost after reinstalling the system?
As mentioned just now, the original system partition will be formatted before reinstalling the system. Therefore, the lost files can be retrieved by using the "recover files in partition" function of the data recovery wizard software. The software will deeply scan the data storage area, analyze and integrate the formatted files, and then reproduce the lost files.
Although the data recovery software can help users recover the lost data, the safest thing is that users check the files before reinstalling the system and back up and transfer the data saved in the system partition, so as to avoid the problem of file loss after reinstalling the system.
1. After the data is lost, it is forbidden to store data in the original disk, and any write operation should be avoided as far as possible in the process of data recovery, so as to avoid secondary damage and finally make the data unrecoverable.
2. Do not format. If the partition cannot be opened and prompted for formatting, the user should recover the data at the first time instead of formatting the partition. Because the formatting operation is likely to have a certain adverse impact on the data recovery effect. For the loss of unformatted data, and the file system type of the formatted partition has changed. For example, the original FAT32 partition is formatted into NTFS partition. In this case, after the data is lost, the user can no longer format and change the partition file system type to the original one. The secondary formatting in this case is likely to destroy the files that can be recovered, resulting in the data that can never be recovered.
3. Do not do CHKDSK disk check. Generally, when the file system has a problem, the system will automatically prompt the user whether to check the disk when starting up. In many cases, disk checking can repair some simple file and directory damage, but more often it will destroy data.
4. Do not redo the RAID disk array after data loss. When the server array fails and the data is lost, the rebuilding operation can not be carried out with the array, nor can the array be forcibly put online after the server crashes, because these operations will not have any positive impact on data recovery and will seriously destroy the data.
