    General U disk colleagues are FAT32 format, and now let's put it into NTFS format:
    If your U disk in the computer is L: drive, for example
    1, win + r enter cmd.exe (is to start dos, windows inside) can also annex a command prompt;
    2, using the convert command, note the current disk convert command can not convert it in L: anything other than letter operated here to d: drive directory as an example;
    3, enter the following command to convert L: / fs: ntfs / nosecurity / x
    Preliminary solve the problem.
    Note: This method can only be used as emergency use. Likely to re-login again write protection issues, is being tested ......

    Second, change the policy
    When a write occurs again after the restart protection problems, proceed as follows
    1, select the drive letter U Right - Properties - Hardware
    2, choose U disk icon to Tsinghua Putian, for example,
    3, select Properties - Strategy
    4, as shown to the policy.
    Problem is solved. Because I was in accordance with the above two steps to the changes, netizens can not change the conversion format strategy behind the approach is feasible to try, if possible, the best

    Third, modify the registry
    1, open the Registry win + r (ie Start - Run), type regedit.exe
    2, enter the following directories HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ StorageDevicePolicies
    If no entry is established this StorageDevicePolicies
    3, the establishment Dword value named WriteProtect and make it a value of 0
    4, restart
    Above normal operation, but in practice, sometimes performing the above write protection can not solve the problem, the author conducted for this problem the following operations
    5, reboot reboot with U disk, U disk when the system restarts to when the lights flash, unplug the U disk
    6 After the system restarts insert U disk, U disk operations return to normal

    Additional information: registry
    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\StorageDevicePoliciesï¼›HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\StorageDevicePolicies-WriteProtectValue was changed to 0;

    Statement: In addition to two kinds of methods to modify the registry only when the second solution U disk write protected, careful selection, best not to be transformed format operation, if carried out format conversion, FAT32 NTFS data transfer will not be lost, to be U disk back to normal can be formatted to FAT32, FAT32 to NTFS conversion is simple, but in turn the trouble, and after the data transfer easily lost.
