I check event log and got: ‘Failed to open device \?GLOBALROOTDeviceHarddiskVolume8. Error code: 5@020A0019 EventID 8’ Anybody know how I can format the USB stick and remove the error?»

Causes

Usually, if the device you want to clean or format is considered to be blocked (e.g. write-protected) or hasn’t been authorized, the DiskPart command won’t be able to complete properly. For example, you didn’t log in computer as administrator, as some user account might be restricted to use Command Prompt even though you run it as Administrator.

Solutions

Solution 1: Check system event logs to hunt down any problem

Since the error message prompts to see system event logs, you may as well check computer’s logs for more information if you cannot find out what’s causing the problem.

Step 1  Click Start menu to open Control Panel where you can select «Administrative Tools». Note: the option will be available after changing «View by» to «Large icons» at the top right corner.

Step 2  Double-click shortcut «Event Viewer» in Administrative tools window.

Step 3  Expand «Windows Logs» to locate «System».

Solution 2: Run Command Prompt as an Administrator

Step 1  Restart computer and log in Administrator account.

Step 2  Click Start button, click All Programs and then select Accessories.

Step 3  Right-click Command Prompt and select Run as administrator.

Step 4  The UAC (User Account Control) dialog box comes up and you should provide permission or password to confirm the action.

Step 5  Type and execute DiskPart command again and the «Access is denied» error won’t appear.

Error 2: DiskPart has encountered an error: The media is write protected

Symptom

«Hi, I have a 8GB SONY USB flash drive and I want to repartition it using DiskPart, because the flash drive turned to 189MB for no reason. I tried to format it in Command Prompt but receive the error ‘DiskPart has encountered an error. The media is write protected. Sine the USB flash drive does not have a write-protect switch. Any ideas can help me remove write protection? «

Causes

It is easy to lose access of what you have stored on drive, as there are changes that files are deleted by accident or get damaged by virus. Some mass storage device provides write-protection function to protect files and folders. However, some drive still can be set to read-only even though there is not a write-protection switch. Reasons behind write protection error vary from one to another, let’s see possible causes together.

• The storage media is damaged by virus or malware and cannot work properly.
• The read-only switch is placed to ON side by accident and the media becomes un-writable.
• The disk is set to read-only in Property or Registry to prevent writing actions.
• The drive has physical damages, such as bad sectors.

Solutions

Solution 1: Remove write protection using DiskPart

Step 1  Run Command Prompt as administrator, type in DiskPart and press Enter. To open Command prompt, press Win + R, type cmd in Run box and click OK.

Step 2  Type «list disk» and press Enter. Then all disks on your computer will be listed.

Step 3  Type in «select disk #» and press Enter key. You should replace # with the actual disk number, for example, you want to remove read-only for volumes on disk 1, then you should enter «select disk 1».

Step 4  Input «attribute disk» and press Enter. Now you can see whether the disk is read-only or not.

Step 5  Type command «attribute disk clear readonly» and press Enter. The «Current Read-Only State» and «Read-only» will be set to No. Then you can try DiskPart to check whether the error is fixed.

Solution 2: Remove read-only state in Registry Editor

Step 1  Right-click Start button on the bottom-left corner and select Run. Type «regedit» in search box and press Enter key. Click «Yes» if you are asked by User Account control.

Step 2  Expand keys following the path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStorageDevicePolicies.

Step 3  If there is not StorageDevicePolicies on your computer, you need to create one. Right-click on «Control» and select «New» and «Key». Then name it as StorageDevicePolicies

Step 4  Right-click StorageDevicePolicies and select «New» and «DWORD (32-bit) Value». Then rename it as «WriteProtect».

Step 5  Right-click the newly created «WriteProtect» key and change the Value data to 0. Then click OK and close Registry Editor.

Error 3: DiskPart has encountered an I/O device error

Symptom
