Category 2 Solution: Fix Write Protection and Corruption Errors via Regedit/Registry

For the situations in the second category, simply formatting the disk will likely not be sufficient. Instead, it will require some manual editing of the Registry.

1. Repair a Write-protected SanDisk SD Card or Flash Drive

If it's about removing the write protection on a micro SD card, there are three ideas to fix a write-protected SD card, including unlocking the lock switch, toggling the loss lock switch, and changing the lock feature in the mobile device settings.

Since a USB flash drive doesn't have a lock switch, you can only try to fix a write-protected USB drive:

If you are not professional in computing management and not familiar with command lines, don't worry. EaseUS R&D team has promoted a fresh kit for helping you resolve the write-protection issue on your hard drive, external hard drive, USB or SD card, etc., devices.

EaseUS Tool M is a practical computer fixing tool that is safe and light-weighted. It's a perfect alternative to the command line. 

Use this one-click tool to solve the write-protection issues on your own:

Step 1: DOWDLOAD and install EaseUS Tool M for free.

Step 2: Run EaseUS Tool M on your PC, choose "Write Protection" mode.

Step 3: Select the device which is now "Write-Protected" and click "Disable" to remove the protection.

2. Repair SanDisk Device Not Detected by a Windows PC

The official SanDisk knowledgebase states that a corrupt registry entry can cause your SanDisk product to not be detected by the computer. Removing the registry keys created upon installation of your SanDisk product will allow the computer to fully reinstall the device and may resolve the issue.

Step 1. Back up the registry

1. Unplug the device from the USB port.
2. Run regedit.

Windows XP: Go to "Start" > "Run", type in regedit and then click "OK".
Windows 7, 8 and Vista: Click the Start button, type regedit in the search box, and then press Enter.
Window 10: Type regedit, in the 'Search the web and Windows' field (lower-right) and then select 'Regedit - Run Command'.

3. From the registry menu, choose File > Export.
4. Name the file SNDK.reg and save it to your desktop.

If you experience any issues after editing the registry, you can restore this backup by following steps 1 through 3, but choosing File > Import instead. Choose the SNDK.reg file that you backed up, allow it to import, then restart your PC.

Step 2. Remove SanDisk info from the registry

WARNING: DO NOT delete any registry keys other than keys that include VID_0781, the SanDisk device’s keys. Deleting important registry keys can result in booting issues and other system malfunctions. 

1. From the registry menu, click "Edit" and choose "Find".
2. Type in VID_0781 and click "Find" Next.
3. Once the search finishes, right-click the highlighted registry key and select "delete".
4. Press the F3 key to find the next registry key that includes VID_0781.
5. Right-click the highlighted registry key and select "delete".
6. Repeat this process until the search returns with No results Found.

NOTE: Under Windows 7, 8 and Vista, some registry keys may be protected and cannot be deleted. Simply skip over these keys if you receive a message that the key cannot be deleted.

7. Once all registry keys containing VID_0781 have been deleted, reboot your computer.
8. Plug the device into the computer after it's finished rebooting. The device will be reinstalled.

If you have trouble completing this process, there is another way that you can try to fix a USB flash drive not showing up in another way.
