You should now see the Command Line Utility, which looks like the following.

Type in the command DISKPART and hit Enter. Diskpart is a disk-partitioning tool that is built into Windows and is accessible through the Command Line Utility. With it, we can change the values associated with your USB drive.

Now type LIST DISK and hit Enter. You should see a table something like the one below. It shows two disks being available: the Hard Disk Drive (HDD) as Disk 0, and the USB flash drive as Disk 1. We know that the USB flash drive is Disk 1 because it is much smaller than Disk 0 at only 7441 MB versus 298 GB. Be very careful from here on out! You can see that if you start working with the wrong disk, things can get ugly quicker than when the lights come on at last call.

At this point, type SELECT DISK 1 and hit Enter. You’ll be rewarded with the knowledge that Disk 1 is now the selected disk. Type in ATTRIBUTES DISK, and Diskpart will tell you what you want to know about your flash drive. Most important is the first line Current Read-only State: Yes. This lets us know that, indeed, the flash drive is write protected.

To remove the write protection with Diskpart, type the command ATTRIBUTES DISK CLEAR READONLY. If it works, that will be confirmed by the line Disk attributes cleared successfully.

Double-check this by trying to copy a small file to your USB drive. If it works, great. If you still get the write-protect error, it’s time to bring out the big guns. Software utilities.

Method 3 of 7: Registry Adjustment (Windows)





  1. 1

    Understand the risks. Windows operating systems have a "registry" which contains a great deal of important information. An error here could be making all memory cards and USB drives read-only. While the steps below will safely locate and correct this problem if present, do not change any other settings inside the registry editor, or you could make your operating system unusable.

    • Backing up your registry is recommended before editing it.

    • If you can't find it, try searching for registry error or registry errors instead.
