D4rk0n3 used our news submit to tell us that Microsoft has warned beta testers in release notes, as recently as build 5456.5, to be sure and burn the Vista ISO at very low speeds. They say that a key reason they have found for installation failure, is corrupted or missing data, or at least the inability of the drives to read back the information from the media.
They are recommending burns at 1x or 2x in order to get a reliable result. They say that many DVD burners cannot burn reliably at high speed. We can read the notice in this quote from APC Data and also their thoughts on the issue.

Testing shows that burning at slower speeds greatly increases the chances of a good burn. It has been the subject of rumour for a long time that DVD burning is a risky way of backing up data, because the organic dye layers used in the disc are just that '” organic. They decompose over time, so that patches of a burned disc may become unreadable. But it has been difficult to get a picture for exactly how great the problem is: the CATS DVD analysers required to scientifically test burned DVDs are rare and incredibly expensive. But this sort of data from Microsoft is helpful: statistical analysis on such a wide base of people shows that data integrity on optical discs is a significant problem, even as soon as a disc is burned. |
Hmmm, well I think this logic is a bit flawed. Any
comments out there on why people are not getting good burns? You may also wish
to ponder this issue in the Club CD
Freaks Blank Media Forum. There's already a discussion going on in there, concerning this very subject.
