some ISOs that are bigger than the CD-R you are putting them on will fit. sometimes when I burn, uuhh, my [home] movies, yeah, the bin's sometimes are around 750MB and they burn fine. :ninja: But the size it says on the CD doesn't necessarily reflect the real size of the file. Remember the marketing caca about the size of hard drives? Anyhow, I have a folder full of files with the size of 748MB but the real size is 784, 913, 140 bytes. see where i'm getting at?

try it. the only thing you lose is a .30 CD-R

It depends which format ISO and what type of CD you want to burn.

You can basically burn 80 min to CD, which would be 800 MB if it's audio, but only 700 MB if it's data beacuse of headers, file system, etc. The same thing is emulated with some ISO formats. If the data ISO contains 74 min worth of data, the ISO will be 740 MB. However, if you have a bunch of files lying around that total 740+ MB, chances are you won't squeeze them onto the CD.

Does the CD burning software affect the successfulness of the burn?

I tried to burn the ISO using ISO Recorder on a 700 MB disc and it failed. I extracted the ISO, made an MD5 script, and run it against the disc, and half of the files couldn't be read, including install.wim.

BTW, if you want my MD5 script (mods remove this if it isn't OK), here:

verify_me_with_md5sum.exe.txt

If the ISO is data, it ain't going to work. There are a lot more overheads with data files (error correction for starters).

i was able to fit 727mb onto a 700mb cdr once. anyway, no cd-rw/burner wil lregonize 800/900mb blanks. they'll tell yo uthere's not enough space just like with the 700 ones. anyway, fire up nero and burn it onto a 800mb cd. it'll work fine.

only you 2 morons would fall for this and wouldn't know what these "hints" mean :crazy:

either just say you download and distribute warez or DON'T ****ING "HINT" AT ALL!!!!!" :angry:

70min mode1 cd can have up to 800meg of RAW data. that's why you can burn images that are over 700meg in size
