U disk failure generally divided into soft faults and hard faults, soft faults the most common.

U disk failure generally divided into soft faults and hard faults, soft faults the most common.

 

Soft fault mainly refers to the U disk has bad blocks, leading to U disk can be recognized, but no drive letter appears, or a letter there, but when prompted to open U disk format, and format can not success.

 

Early symptoms may have: U disk read and write slowly, missing files still occupy space. U disk of the bad software is generally low grid through rehabilitation, the commonly used low-cell repair tools Mformat (you can go online to search for download, extremely easy to use, less than a minute to fix), of course, manufacturers also offer a number of U will provide some similar software.

 

I believe that since it is low grid, fault type, too, should drive the Low Level Format Tool Lformat can also be used, but because Lformat run in dos, is relatively cumbersome, and I also did not specifically tried, it is not recommended. Hard disk failure mainly refers to the U of hardware failure, insert U after-hours computer will find new hardware, but the letter can not appear, open U disk without any circuit board burn out or other signs of damage, and the application of methods of soft failures can not resolve the situation.

 

(I long ago there was a U disk, because the letter can not appear to maintenance service department, because the author is also the scene to see if they inserted a long time, and even did not try a soft recovery, saying it was impossible to repair, to direct to the exchange a piece, fortunately, but also an ignorance of these people show.)

 

Hard disk failure is usually in the vulnerable component U crystal damage due to excessive vibration, and the reader can try to spend less than a dollar to buy a piece of electronic market replace the old with the frequency of the crystal oscillator.
