Format memory card via CMD if normal formating methods are showing error

Sometimes memory card shows error while formating, like unable to complete/Failed to format the drive.
You can format the card via CMD.
Open run command, type cmd.
Command window will open.
Type Format ( and drive name ). Make sure you are typing correct drive name. Check it from my computer section.
Command : Format ( drive name ): 
then press enter...you can use /v or /q command if only format doesn't work.

Format ( drive name :) /q
Format ( drive name :) /v
