The new SanDisk Ultra USB 3.0 I purchased has write protection. I attempted to alter it via the command prompt (attributes disk clean read-only), but the problem has not been resolved. I tried to change it through regedit. But still, the issue is not solved. Can you tell me how I can fix this problem?
Usually, the write protection happens on USB when storage firmware traces problems in the storage, including unsafely unplugging. According to your description, you have tried CMD and regedit, but they are not working. Take it easy. On this page, you will discover two reliable solutions that can apply to your problem perfectly.
Way 1. EaseUS Partition Master
When the Windows built-in tools cannot cover you, you can turn to a professional 3rd party tool like EaseUS Partition Master. This utility can efficiently remove write protection from SSD, HDD, and other external storage devices. Moreover, its easy-to-use interface and high data safety can assure users a pleasant experience.
Step 1. Free download and Launch EaseUS Partition Master. Open the Toolkit part and select "Write Protection."
Step 2. Choose your write-protected SanDisk Ultra USB, and click "Disable."
Way 2. Run CMD to Format the SanDisk USB
The second way is to copy and back up your data to another external hard drive and then run commands to change the read-only status and format this USB. Since you already perform clean read-only CMD, I will show you how to format a write-protected USB flash drive via Diskpart:
Step 1. Open Command Prompt and run it as administrator. Then type the following lines to launch Diskpart and format the USB(Hit "Enter" after each):
Step 2. Write exit and press "Enter" to quit the utility.
