DVD DISK WILL NOT FORMAT It proceeds as thogh it's going to, then at the final stage I get a message that it has not succesfully fomatted. I want it to back-up on. I am using 'Vista Home Premium' the device manager lists the dvd as 'ATAPI A DVD DH16A1L ATA DEVICE' I think it a Samsung re-writable DVD player. It will play a movie alright, but I cannot back up to it. I have tried another disk!
