wtf CD's ?

[Afran]

I got these Imation 90 minute CD-R - Jewel 10 : DVD Shop Online Ltd Imation 90 minute CD-R - Jewel 10

They're 800mb but when I try to burn data onto them (Data CD) it says it only has 702MB free even though theyre empty.

Wtf ?

 

[Bahumat]

The size of the disk and the amount of minutes you can record are 2 different things iirc.

The disk may be 700mb, but it can record audio up to 90 minutes.

Sure someone who knows about all this can give a better answer.

 

[Afran]

Well supposedly it's 800mb.

I want to write 736 MB (771,631,104) of data onto it, but it says there's only 702 MB (736,970,752) free.

Is there any way to do it ?

 

[Overdriven]

It's impossible to have exactly 800mb on a disc 1024KB = 1MB - They fucked their calcs up..

You should have around 770mb or so useable.

 

[Daedra]

As the image of the CD shows, the CD can store up to 800 MB of data and 90 min of audio. In most cases, the CD can store an additional 2-6 MB extra, depending on the quality of the CD. So you should have at least 802 MB of actual storage space (not 700 and not 770).

With the old 650 MB the CD could store 74 min of audio and with the 700 MB it was 80 min.

If you're using Nero, depending on the version you're using (especially the older versions) it often miscalculate the CDs storage limit, showing 702 MB no matter what the real limit is.

Try create a CD and ignore its warning. It will most likely result in a perfect burn, since there's plenty room for your 736 MB. If it doesn't, then return the CDs to the dealer and get a refund.

Thanks, that makes more sense. I am indeed using Nero, Nero 7 Ultra Edition.
By default, it's set to overburn. I'm not very experienced with Nero (especially this version), and don't see an option for something along the lines of "Go ahead with it anyway."

781Mb you'll get memory wise They can't give you 800 exactly. Math doesn't add up. Daedra, remember that 1Mb is NOT 1000kb. But 1024.

Trying to tell Afran how much he's most probably to have.

 

[Afran]

Anything above 750 is fine

Any ideas how to make it work?

The discs could be a bit buggered, because there's no way to get around that if they're saying you can't. - Are they CD/RWs or just plain CDRs?

 

[Afran]

cd-r not rewritable

 

[Ingafgrinn Macabre]

CD's with a larger capacity than 702MB aren't standardized, and thus can not be read or burned by all CD-writers.
For more information read the "orange book", or perhaps not, since it's quiet a complicated book for the non-tech-spec-savvy person (I certainly would fall asleep upon reading the first 2 pages )

Yes, I know that 1 KB is not 1000 B and 1 MB isn't 1000 KB. But unlike HDs (where the manufactures falsely label the HD, trying to make you belive you're buying a 500 GB HD, when it's only 465 GB), the CD manufactures aren't cheating with the numbers. You get 700 MB (734.003.200 B) of actual storage space on a 700 MB CD, etc. With DVDs though, we're back to the old cheating the customer. A 4.7 GB DVD only holds around 4.38 GB data.

But, Afran, it may be as Ingafgrinn Macabre said; maybe your CD writer just doesn't support CDs of larger capacity than 700 MB. I have a few 850 MB lying around, and Nero show these as only being 96 MB. My new drive just doesn't support these.

It's time to enter the age of DVDs.. and they're cheaper too

I have plenty of DvD's - but this needed to be a CD.

gona sound stupid and all, but if its for transferring to another computer then (if its not 1 huge file) you could burn them on 2 diff cd's then put em in the same folder on the 2nd computer? fuck the environment and all this save the children crap - frankely if i do everything for my children, how are they gona learn for themselves!?!?!?

It's not ^^

CD-Recordable FAQ - section 3

Subject: [3-8-2] How well do 90-minute and 99-minute CD-R blanks work?
(2004/03/04)
Small quantities of 90-minute and 99-minute blanks have appeared, but since their introduction in late 2000 they haven't become as commonplace as other lengths. Indications are that many recorders and some software don't really work with the longer discs.

The discs have capacity of roughly 791MB (90 min) and 870MB (99 min). However, all the capacity in the world won't help you if you can't read the disc after you write it. If you're interested in larger but incompatible discs, your best bet is probably DVD-R. Other alternatives, such as DD-R/DD-RW (section (2-37)), ML (section (2-39)), and GigaRec (section (2-46)) never really took off.

CD time stamps are two digits (binary coded decimal, in case you were wondering), so exceeding 99 minutes isn't possible. You could, in theory, declare there to be 99 seconds in a minute and 99 sectors per second, but that would break just about everything that tried to read one. The limits of the specifications are being pushed at 80 minutes and even harder at 90, so don't expect much more out of CD-R. Some knowledgeable individuals have stated that the longest possible CD-R is 79 minutes, 59 seconds, 74 blocks long, because of the way that the last possible start time of the lead-out is encoded, but you can use "overburning" (discussed in the next section) to write past that point. (Experiments suggest that the actual limit is 88 minutes; either way, you're pretty far from 99.)

See http://www.mmore.com/download/Technical_write-up-MMORE_90_min.pdf for a tutorial on burning 90-minute discs with Nero. In short: make sure your drive supports overburning, set "Enable overburn" in the "Expert features" tab of the preferences, ignore the warnings, and cross your fingers. Always verify the disc afterward.
