u disk singular fault handling a

Today, floppy disk has become more and more satisfied with the needs of the vast number of educators, U disk replacement floppy disk has become inevitable. The author of the school for all teachers with a U disk (64MB), teachers can no longer worry about storing data copied to the floppy disk can not read out, and do not worry about the capacity too small to store. But recently, I encountered a U disk singular failure:

　　failure phenomenon : stored on a U disk files appear garbled phenomenon. Using the system for Windows Professional, u disk with extension cord with the computer USB interface.

　　Fault Analysis : According to the above phenomenon, the author analysis, there may be the following failure reasons:

1. System Virus Infection

2.USB Interface Damage

3.USB Extension Cord Damage

4.U disk itself is corrupted

According to the above fault analysis, the author first upgraded the rising anti-virus software 2004 enhanced version and search the virus, the results did not detect suspicious viruses. Another to find an undamaged U disk for testing, the results can be used normally, the second to third cause of failure is also excluded. The author found that the previously stored files on U disk can be read out normally, but the current stored files appear above the garbled phenomenon. The author also thought of whether a U disk will be the disc fragments, and then the U disk files all copied back to the hard disk, with the system with the format of the function of the U disk format processing, fault resolution.

　　Summary : The above fault is mainly caused by disk debris, we do not mistakenly think that the U disk has been damaged, can not be used normally. U disk fragments of the formation, is generally due to improper use of the method caused. When you remove a U disk, be sure to ensure that the USB disk is not in the read and write data state.
