There are three expert-recommended methods to fix Windows Unable to complete the format on an SD card or USB pen drive. I have described all the methods below and you can choose anyone you think is easy, quick, and consumes less time and effort.
Method 1: Windows Disk Management
Microsoft has provided Windows users with a Disk Management utility that can perform some basic operations like disk formatting, and partition-related activities like Shrink, Extend, Delete and Create. Here are the steps to use this built-in tool:
Step 1: Select “Manage” from the context menu of the computer icon in Windows 7 or This PC in Windows 8/10/11. Go to “Storage” > “Disk Management” in the pop-up window’s right pane.
Step 2: Locate the SD card or USB device that is displaying an error message about being unable to complete the format. If the drive has any partitions, erase them all and you’ll have a single volume.
Step 3: Select “Format” from the “Right-Click” menu on the drive. If the device is greater than 4GB, use the NTFS file system; otherwise, use the FAT32 file system.
Method 2: Diskpart
Before Windows, Microsoft released MS-DOS which is a very powerful operating system in itself. It contains a disk format and partition utility known as Diskpart. However, MS-DOS does not have a graphical user interface and is hence difficult to operate. Here are the steps you need to follow to use Disk part on your PC.
Step 1: Right-click on a Windows icon, type command prompt in the Search box, right-click on Command Prompt, and choose “Run as administrator.”
Step 2: In the Command Prompt, type diskpart and press Enter.
Step 3: To quickly format a hard drive, but the command lines below into DiskPart and hit Enter each time.
- list disk
- select disk (number)
- list volume

One of the greatest partition applications for Windows users is EaseUS Partition Master. With just a few clicks, you can format a hard drive partition. You can choose NTFS, FAT32, EXT2, or EXT3 to format your SD card or USB device. Here are the steps:
Step 1: Select “Format” from the context menu when right-clicking the hard disc partition.
Step 2: In the new window, select the partition’s Partition label, File system, and Cluster size, then click “OK.”
Step 3: A warning message appears; click “OK” to proceed.
Step 4: In the top-left corner, click “Execute Operation,” then “Apply” to begin formatting the hard drive partition.
A smaller cluster size means less disc space is wasted. The file allocation table (FAT) will be larger the lower the cluster size is. EaseUS Partition Master offers other one-stop partition and disc management options for your Windows PC in addition to hard drive formatting, such as:
- Create, delete, and merge partitions, as well as resize/move partitions
- Even if the target partition is smaller than the source, you can copy and clone a whole disc to another.
- Convert a logical partition to a primary partition, a primary partition to a logical partition, a FAT partition to an NTFS partition, an MBR disc to a GPT disc, or a GPT disc to an MBR disc.
- To speed up Windows, migrate the operating system to a solid-state drive (SSD).
