How to Tell If CD-R is Blank?
I have an application trying to write to blank CD-Rs that keeps failing. Is
there a good way to determine if the CD-R is still blank, that doesn't rely on having some third party software installed? -- W |

Ed You could use a Device Manager or Explorer approach, do Properties, and see if there is a tab for the thing. Then, look for a "Populate" button, to scan the current media and tell you stuff about it. It might record three sizes in KB. If all three were zero, perhaps that means the media is blank. Not sure. The other possibility, is the disc could be burned multi-session and not be closed, in which case you could add another session to it. I didn't see anything in that interface, that indicates whether the session is open or closed (finalized). The disadvantage of the system-provided info, is not printing in "plain English", whether the thing is blank as such. A visual check (hold it up to your eye), usually tells you whether the laser has done anything to it. That's not very scientific though. A third party utility might use language more suited to humans, whereas the system provided info might leave you guessing whether it is blank, heuristically_blank, or whatever. The contrast ratio on CD-RW might not be as useful as that on CD-R. I can usually tell by looking with the ole eyeball, whether the CD-R on the top of my spindle, is used or not (thrown back by accident). Paul |

I can always see if a disk is used, even without glasses. :-) I've had cases where I've put a CD-R in for burning, started it, suddenly changed my mind, and stopped the burner.

Well, for me it works to simply remove it, put it back in the tray and leave it up to either Windows or some program to see what it says. Win7 AutoPlay will show you what it makes of it. Ed |

(Like you, I'd install 3PSW on my own PC.) One of the main ones is that when you install the 3rd party ones (like Nero, which comes with many optical drives), it disables the native Windows version, and then you are stuck with the reduced functionality of the 3rd-party one. Windows 7, for example allows you to format a DVD-R disc so you can write to it with a batch file. Nero (like several others) only allows you to format RW discs, which is a nuisance restriction. -- Steve Hayes from Tshwane, South Africa Web: http://www.khanya.org.za/stevesig.htm Blog: http://khanya.wordpress.com E-mail - see web page, or parse: shayes at dunelm full stop org full stop uk |
