There are four major problems to be aware of when using a USB flash drive.

Newcomers need to be more careful when they are a lot of people. If they are serious, it will cause damage to the equipment. It is very common for novices to damage the USB flash drive. Today, I would like to pay attention to what to use when using a USB flash drive. problem.

U disk (also known as flash drive) with its low price, large storage space, relatively fast access speed, has now replaced the floppy drive as one of the preferred components of our assembled computer. Although it claims to have more than 100,000 times of erasing, if you do not pay attention to it in daily use, it is easy to appear "early". Through the daily use of the lessons, the author summarizes the following possible factors that may lead to the U disk "life reduction", and discuss with friends.

Finishing debris, more harm than good

For many friends who care for the machine and are good at maintenance, they must have developed a good habit of defragmenting the hard disk. After frequently performing hard disk operations, deleting and saving a large number of files, or after using the system for a long time, the hard disk should be defragmented in time. Therefore, many friends, after using the U disk, certainly want to use the disk defragmentation tool to defragment the U disk. The idea is good, but you know, it is counterproductive. Because the way to save data information on the USB flash drive is different from the hard disk principle, the fragmentation of the file generated by it is not suitable for regular finishing. If it is "forced", it will affect its service life. If you think that the file size of your U disk is too frequent or has been used for a long time, you can consider temporarily copying the useful file to the hard disk and completely formatting the U disk to clear the debris. Of course, you can't frequently clean the USB flash drive by formatting it, which will also affect the life of the USB flash drive.

Save and delete files, once

When you are working on a USB flash drive, whether it is saving files or deleting files, the USB flash drive will refresh the data in the flash memory once. In other words, every time you add a file or reduce a file in a USB flash drive, the USB flash drive will be automatically refreshed once. When copying multiple files, the order in which the files are copied in one by one is performed. At this time, the U disk will be continuously refreshed, which directly causes the loss of the physical media of the U disk. Therefore, when using U disk to save files, it is best to use WinRAR and other compression tools to compress multiple files, package them into a file and then save them to a U disk; the same reason, when you want to delete the information in the U disk (unless it is Formatting), preferably also in one go, so that the U disk refreshes the least, rather than repeating the refresh. Only by reducing the loss of the U disk can the actual life of the U disk be effectively improved.

U disk is not used, remember to " laid off"

Many friends with U disk, often insert the U disk into the USB interface, in order to facilitate the copy at any time without unplugging it. As you can see, this method poses a significant security risk to your personal data. First, if you are using Windows 2000 or Windows XP operating system and have the sleep memory function enabled, then when the system enters the sleep standby state and returns to the normal state, it is easy to modify the data in the USB disk. Occur, the loss of important data will make you cry. Second, for friends who often go online, the resources on the Internet are too "rich". In addition to useful resources, there are many Trojan viruses everywhere "harassing", maybe someday "slip" into your U disk, right The data therein caused irreparable damage. Therefore, in order to ensure that the U disk data does not suffer losses, it is best to unplug it after copying the data; or to turn off its write switch.

Hot Plugging and Unplugging

As we all know, U disk is a device that supports hot plugging. But pay attention to the following aspects: When the U disk is reading or saving data (the U disk's indicator light is blinking continuously), you must not pull out the U disk. If you pull it out at this time, it is easy to damage the U disk or Is the data; in addition, usually do not plug and unplug frequently, otherwise it is easy to cause the USB interface to loose; three, in the process of inserting the U disk must not use brute force, when you can not insert, do not hard insert, you can adjust Angle and orientation.
