Recognizing Dual Layer disks

Hi, as we all know quite a few of the Windows own things are basic at best, so in this case obviously not able to see dual layers on a disk.
However the software you mention will no doubt be one of the usual things bundled in by Asus and is a third party software, which does show that your drive itself as well as the software can handle dual layer disks, even though Windows obviously can't.

Actually Tony I wouldn't think it is possible for Windows to copy something it can't read anyway. I guess I am really confused on that subject besides as because newer Mac OS can read many Windows programs doesn't mean Windows can read Mac OS so how could it copy it then? Not sure if what I said even makes sense.

 

That is really fascinating Tony. TG as long as we can learn.

 

Hum, you have me wondering now Rich, so here is a guess, firstly I think perhaps it depends on original format of the disk.
If just plain Data, Windows may not be able to read it as such as the data will obviously be MAC, however, it doesn't mean Windows can't actually handle it in the form of a stored file, after all it is still data which right at the core is still strings of 1's and 0's.
That train of thought comes about due to the many times an odd data file with odd extensions, when Windows reports it can't open the file and asks for a program to do so, yet it can still store that file.
In this case, I assume storage is only temporary so it can be burned as an ISO, or whatever MAC requires.

That is my take only on what Windows itself can do with the data.
However, the question still hands on Tony wondering why Windows only saw layer 0 and not layer 1. I can only assume my first reply where I said that the basic part of Windows explorer which is what saw the disk in the first place, cannot handle or use the extra bit of coding or technology required to see layer 1.
However, the third party software quite obviously does have that extra bit of technology or coding built in so it can see layer 1 as well as layer 0
We also must assume that the disk drive and read write heads are also capable of handling dual layer disks, just a shame Windows itself cannot.

Before writing that, I did go doing a little research as some of the previous, and your post Rich, did puzzle me, consequently I found a general article on Wikipedia regarding DVD disks, however with an interesting bit of technical explanation part way down the page regarding dual layer disks, have a look here :-

Just scroll down to the heading of Dual Layer Recording.
The whole article is interesting and some did refresh my memory of what I already knew about disks in general any way.

Wow good find Nev as I always wondered why dual layer disks are so much slower at recording but that makes total sense. And you are right it has been
a while since I read anything about that also, like you.
