I ask because my daughter bought a brand new laptop and within days it reported an ISO fault. It was replaced but the next one is also reporting the same thing and she is wondering if it is something she did, a fault of the laptop or a programme fault. she wants to know if she can fix it herself and why it happened. she doesn't burn disks.
That would tend to point to a problem with the disks which she was using especially if it was the same disks showing up the problem with two different laptops. OR possibly the cd/dvd drive if it is the removable type and was not change when the laptop was changed.
