I had tried to format my sd card.. That Contains Some Photo and Music Files.. I Tried to Delete all but I cant delete one music file that has been corrupted... the drive don't take any files..

I tried to format this usb drive using these ways

Firstly.....
1. Go to My Computer
2. right click on selected disk.. then format...
but computer displays message "windows was unable to format".

Secondly.....
1. Right Click My Computer-Manage-Disk Management
format by right clicking the selected usb drive..
but computer can't format the drive again.

Then.....
run command-formatG:(G is the usb drive containing sd Card)
computer displays "Invalid media or Track-0 bad-disk unusable

I Tried to change that drive from FAT to NTFS by run-command-convert g: /fs:ntfs
but computer displays g:was not converted to ntfs

I Tried command-chkdsk
Computer dispalys--- warning! G parameter specified. your drive may still be corrupted after running CHKDSK
also tried cmd- chkdsk/I
computer displays------- can't lock current drive.

Do Anyone has Idea to Format This SD Card... or The Card Can't be formatted....... Please suggest me
