    You get an error saying 'Unable to lock volume for exclusive access'

    A.K.A. 'DeviceIoControl(FSCTL_LOCK_VOLUME) Failed!'

    Another program is currently using the drive. You need to find out what it is and shut it down!

    The only way I know of finding out what else has a 'handle' open to the drive is by using Process Explorer from www.sysinternals.com

    Load it up and click 'Find' -> 'Find Handle...'

    The type 'cdrom' and click 'search'

    See if it comes up with any results

    If it doesnt, try searching for the drive letter of that drive - i.e. 'F:'

    If it finds something, click on it in the search window. The main window should then highlight the process / 'File' entry that contains the handle to the drive. You can right click -> close the handle if you like, or just close the entire application, it's up to you.

    You may also get error 'Unknown (34)' sometimes. Cancel the burn, press F5 and then attempt to write it again. It's just windows going mad, nothing to worry about
