One day morning when I was trying to copy some data on my pen drive of 2 GB , suddenly I got message as “You need to format the disk …” and on screen it was popup like below .
So I clicked on Format disk button I got below screen on which I clicked on OK
Still got same error , I though the disk become unusable so tried for second option of Diskpart command as below
Start àrunà cmd
Then “list disk ” to get the disk no for further process. ( its disk 2 in my case)
So followed below set commands for DISK 2 ( which is my Flash drive )
As soon as the format got completed
Thanks to DISKPART … saved my Pen drive.
