Hi, I have a 128GB SanDisk flash drive. When I was downloading, after I woke up, I noticed that my flash drive automatically switched off from the write mode.
I tried with several programs to get it out of write protect mode, but I couldn’t succeed, even one program warned me that it was physically damaged. I wanted to see who could help me with this.
Thx

Your USB flash drive got stuck in write-protected mode. First, check for a physical switch on the drive and make sure it is turned on. If that doesn’t work, try this on a Windows computer: open Command Prompt as administrator, type diskpart, then type the disk, locate your drive, type select disk X (replace X with your drive number), attributes disk clear read only, Clean (this erases all data), create a partition primary, and format fs=ntfs fast or fs=fat32 fast. Another way is to use the Registry Editor: Press Win + R, type regedit, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies, make it if it doesn’t exist, create a DWORD named WriteProtect, and set its value to 0,000. also And his… computer. Scan for malware with antivirus software, use SanDisk’s tools, or try third-party software like AOMEI Partition Assistant. If a malfunction occurs, the drive may be physically damaged. Consider data recovery services or contact SanDisk for a replacement if it is under warranty. If not, you may need a new flash drive.
In general, there are only four methods to remove write protection from your USB drive. Before attempting any repair, first try using chkdsk to repair any system errors on the USB drive. Plus, you also need to ensure that your USB drive is not infected by a virus.
Method 1: Check the Physical Lock Switch
Method 2: Use the Windows Registry
Method 3: Use Diskpart Utility
(There is no need to type other commands after attributes disk clear readonly.)
Method 4: Use Third-party Disk Management Software
(Not very effective because the built-in tools provided by Windows are enough)
You can also check the security permissions for the USB drive.Right-click on the USB drive and select Properties. Switch to the Security Tab and Click on Security. Click Edit, then select your user account and ensure that Full control, Modify, Read & execute, and Write permissions are checked.
If your USB drive have a hardware fault or firmware issue that enforces write protection, keep calm and just let the manufacturer handle this.
Note: Some SanDisk USB sticks have an internal protection mechanism. According to SanDisk, if the USB drive experiences a power fluctuation or other potentially damaging error, it shuts off write access, and there is no way to get it back. They expect you to copy the data to another drive and replace it.
