Thanks Wyzard. Right on point. So, on typical CDRs, drives won't be able to go beyond the recorded region.. But, formatted discs could do that. All due to 'Sync Patterns and Sector addresses'. Thanks..

comment Reading Data from the Entire Surface of a CD, DVD
Oops I had wrong typo it should be "True, there may be NO data to retrieve.". @Ramhound Guess I'd go for a bit more detail: 1.Burn a data CD 2.Burn some extra data in the blank zone(Please dont ask me how to do this ,yet) 3.Access that extra data which is outside the CDFS. As you may have guessed; this is NOT about the everyday CD Structure. So, my question is-How possible is to access(read) the disc surface OUTSIDE the filesystem limits. Hope that helps...

@Breakthrough Thanks. So, I suppose that command allows to read whichever region of the surface of any CD whether it's outside the filesystem. Is there any Windows variant of it?

@Ramhound Since the filesystem is confined to 300MB(in above example) so just a part of the surface is used. The rest of space is concerned 'blank' according to CDFS (or whatever) and not accessed(ignored). So the image is 300MB. But theres an additional 400MB of useless space. Can that region be readed to retrieve whatever data there may be(actually its SUPPOSED to be 'blank' but dont think that far).

True, there may be data to retrieve. But thats not the point. The surface exists no matter its blank or not. Can that region be readed(a Hexdump or a byte stream may be)?

comment Full Control Over CD/DVD burning
Thanks Ansgar. That's a great idea! But suppose I want to write outside the image.. Say the disc has its filesystem in 400MB and I want to do some burning near the outer edge of the disc(in the spare 300MB region). But as @Hennes mentioned, its unclear whether firmware will let us do that.

"consumer CD burners do a lot from the firmware" I guess this explains all of it. If firmware is not blocking us, writting over a CD-R already written should be possible dont you think (true its not erasable, but still can burn the unburned region).
