Sometimes it happens that you connect the USB flash drive to your computer and the instant it starts copying the data, an error message “The disk is write Protected. Remove the write Protection or use a different disk” appears on the screen.
You try one or the other way to get rid of this problem but nothing seems to be working.
Fix Write Protected USB Drive
Don’t worry, it’s not a big issue. This write protection problem on your USB drive might have happened for a number of reasons. In this tutorial, I shall walk you through some simple steps to fix this problem making your device to work again properly.
Here you go:
Some USB flash drives come with a slider switch on their body which puts them into Write Protected mode. Though the newly designed USB sticks don’t have these locks on them anymore, however, if you’ve got one with such a function, make sure the switch has been placed to the unlocked position.
Many times when you plug your USB drive into a computer that you don’t own or public computers, the USB drive gets filled with some harmful files causing it to respond with “Write Protected” error. Therefore when you connect the USB drive to your computer, scan it for viruses at first.
If you find any virus, remove it using your antivirus software. I’d recommend you to use Avast! Antivirus as it has the best virus definitions available out there.
The next thing you should do is to check whether the flash drive is full or not. A full USB disc may cause the Write Protect error message to appear. To find the memory status of your USB disc, navigate to the flash drive, right click on it and select “Properties”. The “General” section of the drive will give you info about the Used and Free space on your USB disc.
If the problem still arises after you’ve tried the above steps then you should better change the values associated with your USB drive. This can be done by Diskpart (a disk-partitioning tool built into Windows) that is accessible through the Command Line Utility.
To open DiskPart Utility:
- Click on your Start Menu > type
cmdin the Search for programs and files field > hit Enter …
- A window will appear > type the command
diskpart> hit Enter …
- Another window will appear > type the command
list disk> hit Enter …
You can now see a list of disks available in Windows. If your USB drive doesn’t appear among the various disks listed here, this method wouldn’t be of any help to you.
If it is listed here, note the disc number against your USB drive. Say it appears at disc # 4. Then type the command select disk 4 in the window (in front of DISKPART>) and hit Enter. After that, attributes disk clear read-only and again hit Enter.
This will clear any Read-Only attribute that might have been present on your USB drive. Now, type exit, hit Enter and leave the DiskPart Utility. Unplug your USB and try it again.
If you are still getting this Write Protected error, then the other way is to go into the registry. No need to worry about it; you only have to do a simple registry change. Here are a few steps to follow:
- Click on your Start Menu > type
regeditinto the Search for programs and files field > hit Enter > the Registry Editor window will now open
- Navigate to
by clicking on the arrows next to the menu items
- When you click on the StorageDevicePolicies, look for a key named WriteProtect
- If it exists, right-click on it and select Modify
- A window will appear showing the Value data for WriteProtect. Most probably the value data is set to 1 (which means Yes, write protect my USB storage device). Change this value to 0 (that means No, don’t write protect my USB storage device) and click OK. This should now fix the Write Protection Error on your USB stick.
If you’re still unable to resolve the issue then there is no other way except to Format the USB Drive. But before you do that make sure you back up all your data from USB drive to your computer otherwise you wouldn’t be able to recover it once the USB drive is formatted.
To format your USB drive, right-click on it and select Format option. The Format window will open. I’ll suggest you to uncheck the Quick format box. This way you’ll not only erase files but also throw any error on the USB drive.
After your USB drive is formatted, it should now start working the way that you expect it to. If it doesn’t, then there is some physical problem with the device.
Try these methods above and you’ll hopefully get this problem resolved. We’ll be more than happy to read any additional troubleshooting tips from you, let us know in the comments below.
