Ask computer experts to explain the mobile hard disk in detail.

Everyone uses mobile storage, mobile hard disk, USB flash drive, MP3 and other devices. Many times, I will save my important data files in it. Actually, this is a misunderstanding. The biggest advantage of storage devices such as mobile hard disks is their ease of use. It is precisely because of its convenience that it is often plugged in and used, and the probability of problems is far greater than that of the hard disk in the computer. In the process of using mobile storage, we must pay attention to:

1, don't touch it, especially the mobile hard disk, because now the mobile hard disk is a box+notebook hard disk (there are also large mobile hard disks that use desktop hard disks. ) The hard disk in the box is basically a traditional mechanical hard disk. This kind of hard disk is most afraid of vibration and bump. Once bumped, it will destroy the internal structure of the hard disk and cause irreversible physical damage that ordinary software can't handle. If the data dropped from the hard disk is of little value, it can basically be discarded. Because even if it can be used temporarily, it may go wrong at some point, just like a time bomb. If you want data, you often need to restore the data at the opening, and the price is basically more than 1,000 yuan. The truly original mobile hard disks are produced by hard disk manufacturers, including: Seagate Western Digital Hitachi Toshiba Samsung. Among them, Samsung shanzhai has the most. Domestic brand: Lenovo Patriot Newman. These domestic brands just choose a good quality hard disk box and then a mobile hard disk composed of notebook hard disks. But now is the era when shanzhai is popular. Choose carefully.

2. Although USB interface design supports hot plug theoretically, in practical application, you must follow the principle of stopping the device first and then plugging it in. Usually used, if it is a desktop, do not use the front USB interface for a long time. Many front USB interfaces have unstable power supply and interface design problems. Assembly machines are particularly prominent. If the mobile hard disk box is not well designed, the damage to the mobile hard disk is fatal. When reading and writing, you must not pull out the mobile storage. If the equipment can't stop normally, it is recommended to turn it off before unplugging it. After all, data security is above everything else. The switching time can be basically ignored.

3. The partition format of mobile hard disk adopts NTFS partition file format as far as possible, which has high security. When using mobile storage to store data, you must not cut it. It should be copied and pasted. After moving the data to the destination, make sure it is correct, and then process the original data. Many friends like to cut, and often appear again. Obviously, the file has been cut to the mobile hard disk, but it can't be opened on other computers. However, the original file has been cut. This situation makes me want to cry. Furthermore, once a file is lost in mobile storage, it is not easy to try to detect it (especially don't use disk detection and CHKDSK command at will). Many times the wrong operation will aggravate the fault and destroy the data. Be sure not to pull and plug the experiment many times at will. If you can, you can change a computer to see if it is normal. Once it is determined that the work is not normal, keep the fault state. Consult a professional for analysis and handling.

4, mobile hard disk unless the original brand comes with hardware encryption function (if it can't be used, it is recommended not to use it). It is not recommended to use any other encryption software program. In order to avoid forgetting the password, I don't know why I can't decrypt it if I enter the correct password. This situation needs to be specifically detected, and the underlying analysis is carried out by using software to analyze the encryption algorithm of encryption software. It should be possible to recover the original data. There are also many times when key information exists on a bad track and correct data cannot be recovered. The bottom operation is somewhat difficult. The best way is to recall the encryption software at that time. Use encryption software to decrypt the status. If the original encryption software cannot decrypt it, it is because the file structure is abnormal. Need specific testing and analysis. Correct analysis and processing should be able to restore the original data.

Be careful to use this encryption method in the future. Many of these encryption programs are trial versions, and some cracked versions have problems. Even if you enter the correct password, you cannot open the hard disk partition.

5. In the process of reinstalling the system, do not insert the mobile hard disk to install the system. Many times, the system will be mistakenly installed on the mobile hard disk, resulting in data loss. Be careful.

6. Don't edit file data directly on mobile storage. If there is a problem, it will be very difficult to recover frequently edited files. You often have experience in data recovery, and you can always find files from a long time ago. After finding a newly edited and urgently needed file, an exception often occurs. Open the garbled code. This is because the partition file format stores data (many USB flash drives are in fat32 format. This file format is prone to fragmentation), and files that are frequently edited will be fragmented, and the preservation is discontinuous, which is more troublesome to recover.

7. At present, shanzhai is popular, and many shanzhai mobile storage products can't guarantee the quality at all. So it's easy to go wrong.

Therefore, everyone should pay attention to the fact that their important materials must be backed up by multi-media. Keep one copy on the computer and one copy on the mobile hard disk. In fact, there are not many really important personal information, and it is not safe to simply save one. Tools such as mobile hard disk can't save data safely for a long time.

When data is lost, don't try to repair it yourself. You know, every situation of losing data is not exactly the same. The experience of many people on the Internet can only be used for your reference. Many times it doesn't apply to your fault. It may even destroy your data. For example, it is a big mistake to use software to restore the problem hard disk circulating on the network after formatting. Although data can be recovered under some special circumstances, the operation in this way itself is not called data recovery. Reformatting is to destroy the original problematic data structure again. This operation complicates the situation of data that could have been completely recovered. Scanning and restoring with data recovery software takes a long time and the effect is not optimistic.

Mobile hard disk, as its name implies, is used to move data. Not for the long-term safe storage of data.

Losing data is not terrible, what is terrible is disorderly operation and recovery. Tools are double-edged swords, and only when used correctly can problems be solved. The wrong use has become the destruction of data.
