How to Fix the Empty Error When Partitioning a Disk in Command Prompt with UTF-8 Encoding

Though "Command Prompt failed to format disk" is a common issue on Android devices, there's no definitive fix for it as of yet. Here, we'll introduce you to two possible solutions.

Method 1: Format the SD Card on Your Computer

The "Volume partition disk failed with null" error on Android phone users typically occurs when the micro SD card is damaged or corrupted, making it unable to be formatted on the device. The card might require repair for the phone to read or recognize it properly.

Most users encounter the "Failed to format volume, returned empty" error when formatting on their phones, so we recommend formatting on a computer instead. Since the micro SD card is damaged, causing such errors on your phone, you can only recover it by performing a full format on a PC. Generally, there are three ways to format an SD card: File Explorer, Disk Management, or third-party formatting software.

Using File Explorer:

Step 1: Open "This PC".

Step 2. Right-click on your SD card and select "Format" from the menu. (If your SD card is not showing up on PC, fix it immediately with the solutions provided.)

Step 3: Assign the USB drive a Windows-compatible file system, and click Start.

Step 4: In the warning window, click “OK” to confirm the action.

Use Disk Management

Step 1: Right-click "This PC" and select "Manage" > "Disk Management."

Step 2: Right-click on your SD card and choose “Format.”

Step 3: Assign a new file system to your SD card and begin the formatting process.

Use third-party tools:

According to our experience, many users have difficulty using the built-in Disk Management due to the “Windows was unable to complete the format” error. If both methods above don't work for you, download a free partition tool – AOMEI Partition Assistant. It's an SD card formatter that can fix Android micro SD card partition body failed and showing as blank issue.

Note: Remove the SD card from your Android phone and connect it to your Windows computer correctly. Wait for Windows to detect the card.

<Step 2> In the new window, set the "Volume label," "File system," and "Cluster size," then click "OK."

Method 2: Send It in for Repair

If formatting the SD card on your computer doesn't help, you should get your phone repaired. In some cases, the problem might be with your phone's hardware and not the SD card itself. If the card works fine in other devices, it's likely that there's an issue with your Android phone, whether it's the motherboard or the SD card slot. This is something that can't be fixed on your own, so take your Android device to the manufacturer for repairs.
