overburning/real data capacity

ooga59 · Newbie Joined: 25 Jan 2003 Posts: 4

I have a cd image file that's about 770 megs that i want to burn onto a CD. I was wondering if i could burn it onto a normal 700 meg CD through overburning. i also read somewhere that 700 megs of storgae on a CD is actually more than 700 megs on a harddrive. is this true? and how much is the true storage space on a CDR? I have also tried getting 800 meg CD's but I can't find them where i live.

it is possible to fit 800mb of music or video onto a 700mb disc, but as for data i am not sure. The true capacity of a disc does depend maonly on what you are wanting to store as music is 10mb per min ( 80 min = 800mb ). Hope this helps, SirQUK

i think that 80 min=700 megs. that's why i don't know how much i can really burn.

I’m not sure what kind of math SirQUK is using but, I found that a 700MB 80min. CD-R calculates out to be 8.75MB per min.. I found a site that goes into detail with the math and might give you a bit more insight into the true capacity of CD-R’s. "www.xdr2.com/CDR-Info/Size.htm" Although I’ve never really tried, over-burning a 700MB CDR to 800MB CD-R, doesn’t seem like the wisest thing to do. I’d pick up a spool of 870MB or lower/higher 90min. CD-R’s on-line somewhere, and forget trying to over-burn that 700MB disk! Remember, you have to make sure that your burner supports over-burning. I know the Plextor 40/12/40x and the Liteon 32x, 48x, and 52x, drives can burn those larger capacity CD-R’s. Good question! Let me know how your progress turns out!

I think you guys missed some important infomation, he said image file Smile

yes you should be able to fit that image file onto a 700 meg cd, as image files can contain extra data that doesn't get put onto the cd Hope that helps Smile

So I tried to burning the image on a 700 meg CD with Nero 5.5. I turned overburn on and set it to a 90 min limit. The image file is a .cdi and nero said it didn't recognize it as an image file but I could burn it anyway. The problem comes when I start to burn it, Nero says that the medium (CDR) does not have enough space but I set the overburn to 90 min which is about 800 megs. So what's the problem? Is it the .cdi file? Or just Nero and I should burn with another program?

You know Khaine, we, or at least I, did miss some pertinent information. I kind of got side tracked with SirQUK’s post. Embarassed

And yes, you're right about image files containing more info. then what gets put on the disk. But 70MB's extra seems like a lot more then just extra information that's not being included. ooga59, the "DiscJuggler" *.cdi image that you have is not being recognize as an image file by Nero most likely because Nero doesn’t support that file type. The web-site www.angelfire.com/extreme/dcheaven/apps/apps.html offers a *.cdi to *.nrg (Nero Burning ROM) converter that you might want to try. The site also offers other *.cdi converters as well. Also, make sure that your burner supports overburning before you make any more coasters. Again, my suggestion is just to buy the 800 some odd MB disks and keep the 700MB for your music. Or better yet, try to trade with a buddy who already has a few of those higher capacity disks. As far as other programs to burn CD's, have you tried "CDRwin"??? Its GUI is simplistic but, I feel it’s a good program to use when Nero isn’t doing what I want it to do.

the original question was: "I have a cd image file that's about 770 megs that i want to burn onto a CD. I was wondering if i could burn it onto a normal 700 meg CD through overburning" I answered"it is possible to fit 800mb of music or video onto a 700mb disc, but as for data i am not sure. " Sorry if i confused ya further:), but it is indeed possible to do what i suggested has roadworker has verified. Perhaps i should of made it clearer:(

So basically what you're saying SirQUK, is that you "overtalked" ooga59's original question... It sounds like you answered the question for the sake of answering the question. This isn't a test! Points aren't taken off if you leave a blank space... Also, for a webmaster your satiric remarks towards me were done deleteriously and in a belittling manner. I DON'T APPEREATE IT! And no, you didn't confuse me further, I understood what you stammering across the first time around... roadworker didn't verify anything you said... And do you know why??? Because you didn't say anything about an IMAGE file, or even go into 1/2 the detail that they went to!!! I don't know how to make myself any clearer for you?!?!? Please feel free to send me a personal message if you wish to discuss this further....

I'm sure you two were only trying to be helpful Smile

sorry for not replying for so long but I've had a bunch of university application that have been distracting me. Anyway, roadworker nailed the problem right on. When I used alcohol120 to burn the image, the actual file that was burned onto the CD ended up being less than 700 megs. Thanks everyone for your help.

hey, a good bit late in posting this, but i was trying to copy a cd that had 1.67 Gb on it.dunno how it had that much on it but i transfered the data into an image file then burned that and i worked fine. just a little confused over how a cd could fit 1.67 Gb on it in the first place.....
