[SOLVED] Windows was unable to complete the format

FREQUENTLY ASKED QUESTIONS (USB PenDrives)
 
Q: Unable to format my Pendrive (USB flash drive) Error showing "Windows was unable to complete the format" ?


Sometimes you cannot (actually Windows cannot) format a USB Pendrive or to a particular File system (eg: NTFS, Fat32, etc) in GUI mode. But still you can try format by using command prompt in Windows operating systems.


Format the Pendrive to Fat32 file system using command prompt.
Login as an administrator powered user and go to "Command prompt" and run the below command. In the below command "g" is the drive letter of the USB flash drive. The command will format the Pendrive to Fat32 file system.
C:\>format g: /q /fs:fat32


Format the Pendrive to NTFS file system using command prompt.
Before formating your USB flash drive to NTFS file system, you need to enable the "Removal policy" of the Pendrive to "Better performance" option. Otherwise windows cannot format to NTFS filesystem.
For doing this, go to "Properties" of the pendrive and select "Hardware" tab and select the Pendrive from the listed disks then click on "Properties". Then click on "Policies" tab and enable the option "Better performance" and click "OK". Now run the below command in command prompt.
In the below command "g" is the drive letter of the USB flash drive.
C:\>format g: /q /fs:ntfs

Click on your START orb-
Right click on COMPUTER-
Click on MANAGE-
Select DISK MANAGEMENT under STORAGE-
Make your selection in the volume column by highlighting/right clicking on it. In my case, it was volume E and then select FORMAT.

VOILA! PROBLEM SOLVED :)
