“Hi, I have a hard drive with multiple partitions on it. I want to run the clean command on it using diskpart. I have selected it but when I run the clean command on it, it just tells me: "diskpart has encountered an error access is denied". Any help would be appreciated! Thanks!”
This error is caused due to a number of factors. It is possible the drive's Write-Protection is enabled or the Command Prompt terminal does not have administrator-level permissions. The article provides you with five solutions.
You can use Diskpart Clean to erase a disk. It will remove any and all partition or volume formatting from the disk. However, as mentioned in the user case, you may also encounter some error messages when we use this tool. We have summarized the following five common errors for you.
If you encounter any of the above errors, you can use the following methods to solve them. Next, I will introduce you the five solutions to fix diskpart clean not working in turn.
When your hard drive or external USB or SD card is not correctly connected to your computer, diskpart will not be able to perform any formatting or cleanup command line. It means you meet the “Device not ready error”. Therefore, you can try reconnecting the device.
First, you need to Unplug the USB, SD card from your computer. Next, you should Reconnect the target device to the computer again. Finally, please Log in to your computer as an administrator.
If the target device is connected correctly, then you can check if the drive is occupied or locked. If so, it will cause diskpart clean not working. And you will see this kind of error message “Data error (cyclic redundancy check)”
Step 1. Keep the target device connected to the computer and open File Explorer.
Step 2. Turn on the target device to check if all data is accessible.
Step 3. If the target device is accessible, then you can clean the drive normally. If the system warns you the device is being occupied by a running program or file, please close it and then confirm again whether the target device is accessible.
This method is to fix the error “The device is write protected”.
When a storage device is locked, encrypted, or write-protected, you may not access or change the drive. Thus, you need to unlock, decrypt and remove the write protection from the target disk at first. Then the diskpart clean will work normally.
Step 1. Run Command Prompt as administrator, type diskpart, and press Enter. To open Command prompt, press Win + R, type cmd in the 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 select disk X and press Enter. X means 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. Then you can see whether the disk is read-only or not.
Step 5. Type command attribute disk clear read-only 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.
When you encounter this error “ Access is denied”, it may be the wiped disk contains system files. So, you need to boot your computer with the installation disk then erase it in PE environment. You can follow the steps below.
Step 1. Insert the Windows installation disc, then boot from it.
