Hard disk is the necessary hardware for computer storage and system file storage. If the mild hard disk is broken, if there is serious bad track, the computer may be stuck or even bootable. The more serious point is that the hard disk is completely broken, then the computer can not enter the system completely. When booting, it will prompt to find the disk, as shown below: If the hard disk is broken, the hard disk will not be found directly, or the hard disk will have abnormal noise. , or there is a prompt in the place where the machine boots to the hard disk, and there is a bad track on the hard disk. In addition, the hard disk enters the system or is particularly slow when running the system. After we used the computer as a daily tool, did you think about one thing: What if the computer's hard drive is broken? Many teachers' computers have been broken, but fortunately not the hard disk. So after a few days of painful waiting, some even got a little money, everything was restored to its original state, and returned to the original work track. What if the hard drive is broken? In a blink of an eye, the accumulated information for a few years is gone. Can you withstand such a blow? Laptops and desktop computers are not safes. They are in danger of being damaged at any time. Your information is dangerous. If you are worried about this danger, you should do a backup of the data from now on. There are several methods: 1. Different computers are backed up at the same time. If you have more than two computers, you can store the data on both computers at the same time. The damage of both computers at the same time may be relatively small, so that the probability of data corruption can be minimized. 2, purchase a mobile hard disk, the entire cost is a few hundred dollars. This way you can put the data on two different hard drives. The safety factor is similar to the above method. 3. Network storage. This method basically does not require any cost, but it is somewhat complicated. Put your data somewhere on the web so you can call your data on any computer without worrying about syncing the data. The data security of large network service providers is very high, and the possibility of data corruption is smaller than the above two methods. The only thing you need to worry about is the security of your account and password. Steps: A. Apply for a space: It is recommended to apply for Jinshan network disk to support computer synchronization. It means to create a Jinshan synchronization disk in the computer. The files inside will be automatically synchronized to the Jinshan network disk in the networked state, which is very convenient. Friends with important data are worth recommending. In order to facilitate data search, try to send the text data as the mail content to the mailbox, not as an attachment. Risks: The biggest risk in this way is that the account is stolen. Once stolen, you may not be able to access your mailbox. Therefore, it is very important to make security protection for your email account. Only when you do a good job of backing up your data from now on, you can handle it when the risks are unexpected. Editor's Note: Generally, if there is no important data in our computer, the hard disk will not be damaged. Take the repair and change the hard disk. In addition, for the friends who have important data in the hard disk, the hard disk is broken, and not too much. Worried, because many times our surface seems to be broken, it may be a small problem, and even if it is really bad, spend a lot of money. Professional data recovery companies may find important data in the hard disk, and for important data. Friends, I recommend to back up your data frequently.
