USB flash drives are also widely used and are also an important device for storage. USB flash drives are written for protection when they are plugged in to the computer. At this time, USB flash drives cannot be used for related operations. The following describes how to crack the USB flash drive write protection solution.

I. Convert the USB flash drive format

Generally, users' USB flash drives are in the FAT32 format. Therefore, we need to convert the USB flash drives to the NTFS format first, so the data transferred from FAT32 to NTFS will not be lost, so users do not have to worry about data loss. In the following method, the default USB flash drive is l in the computer: disk.

1. win + r input cmd.exe (that is, start dos in windows). You can also add a command prompt to the attachment.

2. Use the convert command. Note that the convert command cannot be used to convert the current disk. Therefore, you can use any drive letter other than "L". Here, we use "d: disk directory" as an example.

3. Enter the following command convert L:/fs: ntfs/nosecurity/x

Ii. Change the policy

When the write protection problem occurs again after restart, perform the following operations:

1. Right-click a USB flash drive and choose Properties> hardware.

2. Select Property-Policy

3. Change the policy to be optimized to improve performance.

3. Modify the Registry

1. Open the Registration Table win+r(start now-run the record key to go to regedit.exe

2. Go to the following directory: HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ StorageDevicePolicies

This item is created if no StorageDevicePolicies item exists.

3. Create a Dword Value named WriteProtect and set it to 0. Then restart

The above are general operations, but in actual operations, the above operations may sometimes not solve the write protection problem. To solve this problem, if you restart the system with a USB flash drive, when the system restarts to flash the USB flash drive, unplug the USB flash disk. After the system is restarted, insert the USB flash disk.

Note: In the registry, the value of WriteProtect in HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet002 \ Control \ StorageDevicePolicies; HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet001 \ Control \ StorageDevicePolicies is also changed to 0.

In addition to the registry modification method, the two methods can only solve the USB flash drive write protection for the next time. Please use them with caution.

After converting the USB flash drive format, changing the policy, and modifying the Registry through the tutorial, we finally solved the problem of USB flash drive write protection. If this problem also occurs, try this tutorial.
