Pen Drive is write protectedClosed

Question

Hello,

My 4gb pen drive is write protected. at the time of copy/ delete/ format it is always showing message that the drive is write protected, access denied.
In the properties-ReadyBoost tab it showing "This device cannot be used for readyboost. The device is mounted read-only.

Please help us how can it format it to work properly. thanks

Hi amiya nayak,

Some pen drives come with a read-write lock which can make the pen drive write protected. Please check if your pen drive has such a lock. If it doesn't have a lock and still write protected, check in another computer if it works. Also, you can try the below mentioned steps and see if you are able to remove write protection: 

1. Click "Start". 
2. Click "Run". 
3. Type "CMD" and hit Enter. 
4. Type "Diskpart" and hit Enter, this will open another window. 
5. In this new window type "List Disk" and hit Enter. 
6. Make a note of the disk ### for your pen drive. 
7. Type "Attribute disk clear readonly" and hit Enter. 
8. Type "Select disk ###" (### is the number of the USB pen drive you've plugged in) and hit Enter. 
9. Restart the computer and see if the pen drive works. 

Hope this helps.
