How to Remove Write Protection from USB Drive or Memory card

Some times, USB flash drives or memory cards get read only write protected error, i.e. you can’t copy data in to the USB drive. To solve this issue, here we are sharing some methods to remove the write protection from pen drive or memory card.


Error : The disk is write-protected. Remove the write-protection or use another drive

There are many reasons that cause this problem, let’s see solutions…

Method 1: Check for a Physical Switch

Some USB drives and Memory cards have a physical locking switch that allows you to lock drive and prevent any changes. Examine the USB drive or Memory card closely. If you can find the switch, switch it to the other side to turn the protection off.

Method 2: Scan with Updated Antivirus

The problem can also be caused by some virus activity, so just get it scanned by some updated good antivirus software which may solve your problem. If you don’t have an updated antivirus, Use free Kaspersky virus removal tool.

Method 3: Check Security Permissions

  1. Right click the USB drive and select properties in the explorer windows.
  2. In the properties window, select the security tab.
  3. Select the ‘user’ under user name and click on ‘Edit’.
  4. Check if you have Write permissions. If you don’t, check the option “Full” for full permissions or “Write” for write permissions

Method 4: Using Registry Editor

  1. Open Start Menu
  2. Run, type regedit and press Enter, this will open the registry editor.
  3. Navigate to the following path:
    P.S. If you can’t find the key StorageDevicePolicies , go to step 6.
  4. Double click the key Write Protect in the right pane and set the value to 0 In the Value Data Box and press OK button
  5. Exit Registry and reboot your pc

    If you can’t find the key StorageDevicePolicies in step (3) you have to create it manually.
  6. Right-click HKEY_LOCAL_MACHINE\SYSTEM\CurrrentControlSet\Control\ and select New -> Key.
  7. Enter the name StorageDevicePolicies.
  8. Click on the new registry key StorageDevicePolicies and on the right pan right-click, select New > DWORD and give it the name WriteProtect.
  9. Double click on it and set its value to 0.
  10. Restart your system and check it.

Method 5: Using Diskpart (command prompt)

  1. Start > search bar -> CMD and press enter
  2. Type< diskpart
  3. Type< list disk
  4. Type< select disk # (# is the number of the USB DRIVE you’ve plugged in )
  5. Type< attributes disk clear readonly
  6. Type “exit” to exit the diskpart

Method 6:Format your USB Drive

If the above methods do not solve the problem and still the usb drive is write protected then you can execute a “low-level format” on the drive. Download  HDD Low Level Format Tool to perform the “low-level format” of your USB drive.  After completing the low level format you may have to create a partition in that disk drive.

For that :

  1. Run diskmgmt.msc in Run.
  2. In the disk management window, select the pen drive, right click on it and click on Format.
  3. Click OK. That’s all

Hope one of the solution may help you to remove Write Protection from your USB drive or memory card.

  6. I used Windows Error scanning tool. Do Properties on the drive. Select ‘Check Errors’.
    After it scanned the disk (and found some errors) windows set the USB drive to read-write mode. So I was able to delete and add files.

  7. The seventh point is the trivial situation: A read-only status of hardware was set wrong. Thus he will remain forever.

  8. After trying all the methods discussed here, Fed up and finally this worked for me. I tried formatting, first it did not allow me, after several plugs and trail, it allowed. While format, i choice 64k allotted disk space and after this option, the format successful with read only removed from my usb.

  9. my pen drive is not formatting , when try to format then dialog box appears in the screen check disk is not read only memory then in cmd I cheeked my pen drive is write only then what is the solution

  10. I’ve been trying every possible solution for the past 2 days and the HDD Low-Level formatting finally solved the issue. Thank you a lot!!

  11. I actually just ran into this today and tried every fix above but had no luck. The issue was caused by a Policy set in Symantec.Cloud Antivirus. The Policy will make USB devices read only. (it forces the Write Protect regkey to 1. If you rename, delete or change the value it reverts right back to 1. Once I unchecked the setting and re-applied the policy in the partner portal, I was able to copy files to USB devices again.

    Endpoint Protection: NIS-
