When I am trying to backup my hard drive to DVD+R disks, i can only successfully record to the first disk in the backup. After i have put in the second disk, it records for a while and then displays an error message saying that onecare is unable to write to the disk and that it may be corrupted. I have tried to slow the write speed, but this did not solve the problem. I also successfully backed up another computer with the same type of DVD+R disks, so that is not the problem. How can i get my computer to complete this backup?
