With the increasing popularity of U disk, its role has become more prominent, usually U disk is used to store important data or install the system. However, the market is full of various expansion trays and counterfeit products, so many people dare not easily start, data loss or problems can be incredible. The following website introduces you how to buy a good U disk, how to judge the quality of the U disk. The author summarizes the experience of online shopping U disk several times, and strongly recommends several U disk tool software for detecting expansion disk, repairing U disk, and restoring important data. Mydisktest When everyone buys a U disk, the first thing to worry about is the expansion disk. For example, if I buy an 8g U disk, if it is a expansion disk, the physical capacity is less than 8g, it may be 4g or 2g for mass production expansion, only storage less than its physical capacity. The file will be lost if it exceeds the file! If the seller is blacker with some 256mb, 512mb small capacity U disk to expand, then only throw or try to make a boot disk. Therefore, the expansion is very terrible, especially for some people who use U disk for important data storage. It is just a time bomb. Maybe someday, it will encounter the phenomenon that important data cannot be opened. There is no possibility of recovery because the excess capacity is not written to the flash granules. However, the so-called one thing, Mydisktest software is used to detect the expansion of the disk (Figure). This software has two functions and three modes for users to choose. The rapid expansion test is just as soon as the name is detected, but according to the author's many experiments, this quick test is still very inaccurate. I have bought a capacity expansion U. Disk, normal after the quick test, but the integrity test found the problem, so it is recommended that you use the data integrity test for detection, its principle is to continuously copy the file and see if it can be read, so as to verify the physical capacity The purpose, so the accuracy is also extremely high. The read/write speed test is also an important basis for testing the performance of a USB flash drive. Therefore, the mydisktest software also integrates this function, and the software size is less than 100KB. It can also be described as a small and sophisticated U disk authentication software. Chip worry-free Chipeasy If mydisktest is a tool for expanding the disk and data detection, then this "powered by the U disk home technology team" "chip worry-free" U disk chip detection tool is to detect the U disk chip "artifact" ; It also has the characteristics of short and fine, the software size is less than 1MB, no need to operate, plug in the U disk to automatically detect the U disk, and display various data of the U disk, and provide the mass production solution of this U disk The website link is convenient for users to repair and mass-produce U disk. It also has a unique scoring system that scores the overall performance of the U disk, allowing users to intuitively get the overall performance of their U disk. If the U disk purchaser is worried that the U disk is not genuine, it can be verified not only by anti-counterfeiting query, but also by this software. Especially the U disk of some big brands is easier to detect. For example: Kingston U disk generally only uses the group control of Xinlian, Xinchuang, and Qingtai, so as long as it is not the main control of these three, but it is said that Kingston's products, then only "scrubically add" & rdquo; and the seller . Diskgenius said that the U disk test, the first two software has perfectly solved the true and false problems of the U disk. The third software, Diskgenius, is the largest file, the most functional, and the most complicated software. This data recovery software developed by Easy Digital has two versions, free version and professional version. As far as I can see, the function of the free version is very powerful. This software has extraordinary capabilities. Data loss and misformatting, as well as U disk unrecognizable issues are often faced by us, and we are discouraged. The loss of important files often makes us blame, and most data recovery software is charged. We are in a dilemma. And Diskgenius has solved this problem that has bothered us. The biggest feature of Diskgenius is data recovery. It can find all files that are not covered or overwritten, and can recover uncovered files. Not only that, but it also has dozens of functions such as formatting, partitioning, backup, hard disk bad track detection and repair, boot disk production, etc., which will not be repeated here. I once purchased a Kingston dt101g2 8g U disk online, using Mydisktest and chip worry-free detection, found to be a counterfeit expansion disk. After that, the U disk could not be opened for no reason, nor could it be formatted. After searching online, many people said that mass production was required, so the author downloaded the mass production tool and opened the U disk to view the main control model. Mass production tool downloads have not been mass-produced successfully. But by chance, I downloaded Diskgenius, which was also a curious move. I connected the USB flash drive that had been thrown to the ground to the computer and tried it out. As a result, after formatting with Diskgenius, the U disk is miraculously usable. Although it is still a expansion disk, this software has made me a treasure, so I conducted detailed research and use it and recommended it to everyone. Preparation software. To sum up, in the U disk market where the fish and the dragon are mixed, it is extremely difficult to buy a U disk that makes you feel at ease and feels comfortable. Therefore, in addition to using software for testing, it should be purchased at a regular dealer. In addition, when buying a U disk, it is best to choose a large brand of U disk, not only good quality, anti-counterfeiting query and master control query are convenient, easy to identify true and false. Some second- and third-line products, their own sales are not good, performance is not good, the main control chip is not too many people know, even if the model of the main control chip is relatively inferior, it does not help. Because the seller only has one sentence: the master controller used by the manufacturer to use this master, in a word, makes you unable to refute. EasyRecovery (data recovery software) is also a rare data recovery software that you can download and use.
