The first part of data recovery is not to mess around after data loss, keep a good scene, it will not cause twice damage, this principle must be firmly achieved. In addition, the MiniTool function is very strong, basically can cope with the situation of data loss, and very safe (read-only scan, will not destroy the data), in case of data loss, it is recommended to use this software to try to scan and restore files.

Please read the following notes carefully before data recovery:

The main results are as follows: (1) in the process of data recovery, we are most afraid of secondary damage caused by misoperation, resulting in a sharp increase in the difficulty of data recovery. During the data recovery process, it is forbidden to write new data to the source disk.

2 do not format the partition again. After the user formats the partition for the first time, the partition type changes, resulting in data loss, such as the original FAT32 partition is formatted into NTFS partition, or the original NTFS partition is formatted into FAT32 partition. After the data is lost, the general software cannot scan the original directory format, so the partition is formatted back to the original type again, and then the data is scanned. What we point out is that the second formatting will result in a serious error in the original partition type, which is likely to destroy some large files that could have been recovered, resulting in permanent unrecoverability.

3 do not do DskChk disk check. In general, after an error occurs in the file system, the system will automatically prompt whether you need to do a disk check when it boots into the boot screen. By default, the DskChk disk check operation will begin after 10 seconds. This operation can sometimes repair some slightly damaged directory files, but in many cases it will destroy the data. It cannot be repaired because of its complex directory structure. After the repair fails, a directory such as FOUND.000 will be formed under the root directory, which contains a large number of. CHK is a file with an extension. Sometimes these files can be restored by changing their names, and sometimes they are finished, especially FAT32 partitions or database files with larger NTFS.

4 do not restore the data directly to the source disk. After many ordinary customers delete files, the files recovered by general software are directly restored to the original directory, which is very likely to destroy the original data, so it is strictly forbidden to restore directly to the source disk.

(5) do not rebuild the partition. After the partition table is destroyed or the partition is deleted, if you directly use the partition table reconstruction tool to directly establish or format the partition, it is easy to destroy important areas such as the original partition file allocation table (FAT) or file record table (MFT), resulting in a great increase in the difficulty of recovery. In the practice of recovery, we have encountered many times that after the partition table was destroyed, we first tried several partition tools that could not recover the data before we wanted to ask a professional for help. as a result, we found that after the role of a variety of partition tools, destroyed some important directory files, resulting in incomplete file catalog recovery, some large files can not be recovered. According to the initial partition loss described by the customer, these files can generally be fully recovered, which is really a pity. Before rebuilding the partition table, professional data recovery personnel will first locate the specific location of the partition (logical sector number), and then use the sector view tool to check several important parameters of the partition, such as DBR/FAT/FDT/MFT, before modifying the partition table, and after modifying the partition table, during the boot process of the system, the system will be prohibited from doing dskchk to destroy the partition directory to ensure that the data will not be destroyed.

After the data is lost, it is forbidden to store new files in the partition that needs to be recovered. It is best to close the download tool, do not surf the Internet, shut down unnecessary applications, and then scan and recover data. If the partition to be restored is a system partition, if there is no important data such as a database in this computer after the data file is deleted and lost, we recommend that you power off the computer directly, and then hang the hard disk to another computer to recover, because in the shutdown or boot state, the operating system will write data to the system disk, which may destroy the data.

7 do not redo the array after the array is lost. In the practice of saving the server array, we have encountered some network managers forcibly bring the array online after the server crash, even if the disconnected hard disk is forced online, or do rebuilding directly. These operations are very dangerous, and any operation written to the disk may destroy the data.

That's basically it.
