Fixes for 'The Format Did Not Complete Successfully' 

Despite an old topic for a long time, 'the format did not complete successfully' error is still a headache for many average users. Usually, such an error message means Windows was unable to complete the format for a hard disk or a removable storage media in a normal way, so you'd better stop trying.

To ease your worry, we find three best ways to help fix the problem on USB, SD memory card, the external hard drive in Windows 10,8,7.

1. Using Windows Disk Management

Unknown viruses on your computer may stop you formatting your disk drive in a large extent, so run a virus check using the security software at first attempt. Afterward, try to format again in Disk Management carefully.

Step 1. Execute diskmgmt.msc from whatever Windows command line interface you're using.
Step 2. Right-click on the disk and select "Format" option.
Step 3. Follow the format wizard to complete the format process.

Or you may perhaps delete the volume, create a new one and then format.

2. Using Command

Step 1. Type cmd in the Search and open a DOS prompt.
Step 2. Type command: attrib -r -h -s ./s x:\*.* (replace x with your pen drive's drive letter, such as g or f)
Step 3. Type command: FORMAT X: /FS:FAT32 /Q /V:PenDrive (replace x with your pen drive's drive letter, such as g or f)

This will reformat the pen drive into the FAT32 file system.

3. Using Third-party SD & USB Format Utility

EaseUS Partition Master is the best USB format tool that helps resolve Windows format error. You may as well use the last method as the first because it's the simplest comparing with the former two methods. Above all, you can hardly make a mistake with it.
