I need to remove the "write protection" on my 64GB USB storage disk. I have too much to lose and all my backups for my profile are on here. I cannot write to it OR download from it. There is not a mechanical up or down flip switch. How it got write protected is beyond me. I only noticed this because my user profile became corrupted and I wanted to reinstall the programs from my USB drive back onto my profile. It says it is write protected and to remove it or use another disk. I don't have another disk. I'm using Windows XP Pro, Service Pack 3 on an E machine 3.33 GHz.

Thanks to wiseman378 for the "diskpart" solution however I have found this to be a temporary fix. Somehow, my external drive becomes write protected again and I redo the "diskpart" script. It defeats trying to run auto backups. Anyone have a permanent fix?

Method 3 of 7: Adjusting the Registry (Windows)
1Understand 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.
Disable Write Protection Step 2 Version 2.jpg
2Open the registry editor. You can access the registry editor by entering regedit into the Search field in your Start menu. Windows 8 users can type regedit when viewing the Start screen. Press enter on your keyboard to search, then open "Registry Editor" when it appears.
If you can't find it, try searching for registry error or registry errors instead.
Disable Write Protection Step 3 Version 2.jpg
3Navigate to HKEY_LOCAL_MACHINE. This folder can be found in the Computer section of the registry editor, in the left frame. Click the arrow next to HKEY_LOCAL_MACHINE to expand the folder.
4Navigate to the correct folder. Inside the HKEY_LOCAL_MACHINE, find and open the SYSTEM folder, then CurrentControlSet, then Control. Finally, scroll down until you find the StorageDevicePolicies folder. If this folder does not exist, see the next step.
Disable Write Protection Step 5 Version 2.jpg
5Create the StorageDevicePolicies folder if it doesn’t exist. If you cannot find the StorageDevicePolicies folder, then you will need to create one before continuing. Right-click in the blank space in the Control folder. Select New, and then Key. Label it StorageDevicePolicies without spaces, exactly as shown here.
Disable Write Protection Step 4 Version 2.jpg
6Change or create the "WriteProtect" entry to 0. Double click on the "WriteProtect" key in the StorageDevicePolicies folder. Change the “Value data” field from 1 to 0. Press OK. If you created a new StorageDevicePolicies folder, follow these steps instead:
Open the new StorageDevicePolicies folder, then right-click in a blank space. Select New, and then DWORD (32-bit) value. Name the new file WriteProtect. Double-click WriteProtect to open it, and put 0 in the value field. Press OK.
You must type each entry exactly, including capitalization, otherwise the key will not work.
Disable Write Protection Step 6 Version 2.jpg
7Reboot your computer. In order for the registry changes to take effect, you will need to reboot your computer. Save all of your work before rebooting.

I have found an old solution that worked on my 64 gig USB drive. No need to modify registry or download software. Try this system fix:
Open a command prompt
type DISKPART press <enter>
type LIST VOLUME press <enter>
type SELECT VOLUME X, where X is the volume number you want to remove the write protect from. In my case is was Volume 6
type ATTRIBTES DISK CLEAR READONLY press <enter>
you will see a prompt that the write protect has been removed
type EXIT press <enter>

Good luck!

This work for me. To the people whose USB are still write-protected after having done this, try unplug the USB and plug it in again.

Go to http://us.apacer.com/support/download/result/3,8,0 and choose "USB3.0 Repair tool"). Download it and unzip the file.

- Connect the usb stick with your pc

- Click "Restore.exe"

- Click "Restore"

- Click again on "Restore"

- You will see "Are you sure you want to continue?". Click "yes"

- Now you will see "Restoring Device", wait till the program finish his job

- After that you will see "Restore Completed" en "Please replug device before use", click on "OK", unplug the stick and put it back again in your pc.

You welcome. I'm glad it worked!

The usb stick will return to the factory settings, probably in exFAT. In that case, you can't copy large files to the stick, so you have to format it to NTFS.

Thank you. That allowed me to format my disk. It was scary because the utility does not tell you which disk it is about to format. I was scared it would format my system disk, but it did format my only USB drive on G:.

The utility crashed part way (perhaps because my disk was from Verbatim not Apacer) but afterwards I was able to use the usual Windows format utility which I had not been able to use before since the disk was write protected.

I have a new 128GB disk on order but until that arrives I can keep using my USB 3.0 disk.
