Windows 7: You need to format the disk in drive before you can use it

If you get this error:

"You need to format the disk <DriveLetter> in drive before you can use it"


Just follow the followoing steps :

1. Go to start button on windows.
2. Type "cmd"  and right click on "cmd" search result icon and click "Run as Administrator"
3. C:\Windows\system32>
4. Now type :     chkdsk <Your hard disk letter>: /f

For e.g If my hard disk is named "f" then just type ----------   chkdsk f: /f

Try it out...I guess it will work.
