Why all of a sudden every day in the U-dish song can not hear, how to do, today small set to give you answer questions, home you can change a computer to try whether it is a computer system problem, if it is not a U disk problem, there may be a fake U disk, test into read out with H2TESTW check whether there is no bad block or capacity is virtual, It tests the unit is byte, smaller than the Mydisktest unit, the best accuracy, almost the same as the actual file if detected to be wrong, the next U disk model detection Tools, ChipGenius3.0 above version.
If you can not read the hardware is damaged, can only be repaired after the reading to save, read out the information sent up to be able to repair the general estimate of the PID vid and chip models under the corresponding production tools under the lower lattice try several times, try a few more versions.
