It's really hard to earn your points It's changed and changed Data recovery is divided into normal data recovery and disaster data recovery, if it is disaster data recovery, as long as the media is not seriously damaged, it can be restored intact, in the case of media damage or data overwritten, it is generally impossible to recover, now introduce some recovery software, one, easyrecovery, the shorter the interval the better, can recover the damaged hard disk like lost boot records, BIOS parameter data, partition table, FAT table, and boot area, (The memory card is successfully tested, but the data is incomplete after partial recovery, in addition to easyrecovery, there is also ***recovery name forgot, the asterisk replaces) Second, finaldata, by scanning the entire disk for file search and recovery, sometimes because a small amount of key information is destroyed, it can cause a large number of data files or even the entire disk to become unavailable, and at the same time, wrong repartitioning and formatting is the most harmful misoperation, Through the powerful recovery function of finaldata, it can help users recover from data disasters (test situation is unknown) with daily maintenance methods Pay attention to temperature, too high temperature will cause circuit components to fail, resulting in recording errors in magnetic medium due to thermal expansion effect, and too low temperature is easy to accumulate electrostatic charge, thereby burning out the circuit; Do not delete files frequently, which not only affects the speed, but also may damage the track; Pay attention to anti-virus; Pay attention to dust prevention; As for why it is damaged, the specific problem is analyzed, if it is not an external force (damage from the outside), it is an internal force (from the error or loss of data), and the virus is not necessarily related, do not always associate the fault with the virus, even if the virus causes the loss of key directories, the same data can be retrieved, formatting is the most wrong method, once the formatted data is overwritten, it can never be recovered, generally speaking, the biggest manifestation of the virus infection is that the operation is slow, the mobile phone becomes stuck, Instead of immediately showing that the memory card is damaged, if there is a destructive virus, your phone will also be infected immediately, so your situation is a data read and write error or an external force damage or partition error, not a virus infection.
