First, the attention will be placed in the dry U disk in the environment, do not let U disk interface for a long time exposure to the air, otherwise prone to surface metal oxidation, reduce interface sensitivity. At the same time, do not have a long time to not use the U disk has been inserted in the USB interface, or on the one hand will lead to aging interface, on the other hand is also a loss.
Second, at ordinary times in the use of careful maintenance, but also very important. For example, never pull out the flash when the flashing lights flash, because when the U disk is reading or writing data, unplugging may cause hardware, data damage. In addition, do not close the relevant program immediately after the backup document, because the flash drive on the light is still flashing, indicating that the program is not completely finished, then pull out the U disk, it is easy to affect the backup. So file backup to the flash disk, should be some time to close the relevant procedures to prevent accidents; Similarly, in the system prompts "can not stop" when not easily pull out u disk, this will result in data loss.
In addition, sometimes u disk running too slow, if you eliminate the infection of computer viruses and U disk itself quality problems, may be because the use of the flash drive does not open the system "open after write cache" this function. After you open the write cache, you can click My Computer by right-clicking select properties → performance → file system → removable disk to hook up before the Write Cache dialog box is enabled, and under WinXP you can open My computer, right-click the removable disk, and select Properties → hardware. Then select the disk drive where the flash memory is located, click properties → policy, select the dialog box for performance Optimization ..., and click OK.
