Disk write-protected solution

General colleagues of the U disk are FAT32 format, now let us convert it to the NTFS format:

If your USB drive in the computer is the L: Disk for example

1, Win+r input cmd.exe (is to start dos,windows inside) can also be attached to the command prompt;

2, the use of the Convert command, note that the convert command can not be converted to the current disk so in L: any letter outside the operation, where the D: Disk directory for example;

3, enter the following command convert L:/fs:ntfs/nosecurity/x

Preliminary solution to the problem.

Description: This method can only be used as an emergency. Re-login may again appear write protection problem, is testing ...

Ii. Change of strategy

When the write protection problem occurs again after reboot, do the following

1, choose the right button-Properties-Hardware

2, choose U disk to Tsinghua Putian for example

3, select Attributes-Policy

4, change the policy as shown in the figure.

Solve the problem. Because I am in accordance with the changes as two steps, you can not convert the format of the following changes to the strategy of the method to try it is feasible, if feasible best

Third, modify the registration form

1, open the registry Win+r (that is, start-run) type Regedit.exe

2, enter the following directory Hkey_local_machinesystemcurrentcontrolsetcontrolstoragedevicepolicies

If there is no storagedevicepolicies item, this item is established

3, establish a DWORD value named Writeprotect and make its value is 0

4, restart

The above is the general operation, but in the actual operation, such as the operation will sometimes not solve the problem of write protection, for this problem I have the following operation

5, reboot with a U disk reboot, when the system reset to u disk light flash, unplug u disk

6, the system reboot after the insert U disk, u disk operation back to normal

Supplementary note: The Hkey_local_machinesystemcontrolset002control storagedevicepolicies in the registration form; The Writeprotect value in Hkey_local_machinesystemcontrolset001control storagedevicepolicies was also changed to 0;

Disclaimer: In addition to modifying the registry method can only be a second solution to the U disk write protection, please choose carefully, it is best not to convert the format operation, if the format conversion, FAT32 to the NTFS data will not be lost, to the U disk restore normal after the format to FAT32, FAT32 to NTFS conversion simple, But the reverse is troublesome, and the data is easily lost after the turn.
