Summary of methods for solving USB disk write protection

Nowadays, the U disk is used more and more widely, and it has become an important device that we usually store. However, when a USB flash drive is plugged into the computer, it will be write-protected. In this case, the U disk can not be used. The following describes the solution for the U disk to be write protected. First, the U disk format of the general user U disk is FAT32 format, so we must first convert the U disk to NTFS format, FAT32 to NTFS data will not be lost, so users do not have to worry about data loss. The default U disk in the following method is L: disk in the computer. 1, win+r input cmd.exe (that is, start dos, windows inside) can also be attached to the command prompt 2, use the convert command, note that the convert command can not convert the current disk, so operate under any drive letter other than L: Here, take the d: disk directory as an example. Enter the following command convert L: /fs:ntfs /nosecurity /x 2. Change the policy. When the write protection problem occurs again after restarting, please perform the following operations: 1. Select the U disk symbol right- Attributes - Hardware 2, Select Attributes - Strategy 3, change the policy to optimize for performance. Third, modify the registry 1, open the registry win + r (that is, start - run) type regedit.exe2, enter the following directory HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\StorageDevicePolicies if there is no StorageDevicePolicies item to establish this 3, establish Dword value naming WriteProtect and make it a value of 0, then restart the above as a normal operation, but in actual operation, doing the above operation sometimes can not solve the problem of write protection, for this problem, if restarting with U disk restart, when the system restarts to U When the disk light flashes, unplug the USB disk and let the U disk be inserted after the system is restarted. The U disk operation returns to normal. Additional notes: 1. The HKEY_LOCAL_MACHINE\\SYSTEM\\ControlSet002\\Control\\StorageDevicePolicies in the registry; the WriteProtect value in HKEY_LOCAL_MACHINE\\SYSTEM\\ControlSet001\\Control \\StorageDevicePolicies is also changed to 0. 2. In addition to modifying the registry method, the two can only be used twice. Solve the write protection of the U disk, please use it carefully. Through the tutorial to convert the U disk format, change the strategy and modify the registry just now, we finally solved the problem that the U disk is protected by write. If you also have this situation, try this method. This article comes from [System Home] www.xp85.com
