Users questions: I use the U plate, I suddenly encountered power failure, an hour after the call, U disk can be properly displayed, but the two-machine or stand-alone open, are prompted to me, please insert the drive plates, and each time the same, I changed the other computer is the same, and view its properties, available space is 0, has been used space 0, can not format. U disk which has many important things I have not backed up, how to present information which lead out of the trouble that this one, thank you. Other computer display, is the same, property : free space 0, has been used space 0
Experts answer:1. Front USB wireless access Wrong. When the motherboard's USB cable and USB interfaces on the chassis front corresponding to positive and negative phase reversed when such failures occur, which is quite dangerous, because the positive and negative anti-access USB devices are likely to make fire. So as far as possible the USB interface to the rear chassis, but also fewer extension cords. It may be broken I have problems, another USB port see next .2. USB interface to insufficient voltage. When the mobile hard disk connected to the USB port on the front is likely to occur when the system does not recognize the device failure. The reason is relatively large power requirements HDD voltage is relatively strict, pre-interfaces may not provide sufficient voltage Of course, poor power supply may also cause this problem. The solution is to move the hard drive not connected to the front USB interface to replace poor-quality low-power external power supply or to make use of the hard disk box, if able to do so. 3. Motherboard and system compatibility issues. Oh is the most famous of these failures NF2 motherboard compatibility issues with USB. If you are in the NF2 motherboard would encounter this problem, you can install the latest drivers and patches nForce2 special USB2.0, the latest motherboard and operating system patch patch, or not work, then try to refresh the board of BI OS general can solve. 4. System or BIOS problem. When you disable the BIOS or operating system USB USB device does not occur when the system identification. The solution is to open the device with the USB related options. Press F2 or DEL is turn key, enter the BIOS, the e nableusbdevice select enable. 5. Swap to be careful when reading and writing must not pull out, or there may be burning chips. XP, the taskbar icon for more USB devices, open the icon will appear in the list U disk device, select the device out, then you can Unplug equipment that would be more secure. In fact, the problem is very simple software and hardware to judge, in another machine or another system (98 to drive oh) to try on it. Some small problems may wish to use special software to format the next. There to remind you when formatted under WINDOWS To select the FAT, not to vote FAT32. Reference: Baidu Search
