Hi there, Up until tonight I haven't had any issues with IMG Burn but its acting very strange. WHen I put in a blank disc and try to back up my movie I am getting this message. DeviceIoControl(FSCTL_LOCK_VOLUME)Failed! Device:[0:0:0]TOSHIBA CD/DVDW SD-R5372 TU56 (G)(USB) Unable to lock volume for exclusive access. Reason: Access is Denied What in the worl does all this mean and what has happened? I have an external burner and the USB 2.0 and I have never had a problem until tonight. So im needing some help here, is this an IMG Burn problem or a problem with my Burner? Any help is appreciated.
