650 mb a problem?

tobyoftheapes · #1 09-08-2002, 11:18

Hello, i just went out and bought some new CDRW's, when i got home i noticed that they were 650 MB as opposed to the last ones i had which were 700 MB, i know that you can copy larger games onto the 700 MB CD's will this also work with 650 MB disks? For instance, i am trying to back up my copy of warcraft III (about 750 MB) can i burn this on a 650 MB disk? Thanks for your help!

I don't think so..Are you sure the Warcraft you have isn't the image? Because you put the game in the HDD the image tends to stretch..I have not seen CD games that over 700 megs..Most of them are under 700 megs..
But relatively speaking if it's really 750 then you can't put it on the 650..It's common sense..

Unless you want to do a Over Burn..

650 mb disc actually holds 740 mb of data. without overburning. that 750 mb would fit with the slightest overburn. images dont 'stretch'. they include the error correction, and windows bases cd size on that. i think its the c3 errors, but nobody really cares about that here

I do. Explain to me why does Image stretch when you put it in the HDD..For example would be PSX game using a CDRwin?
See my point? That's what I was talking about..I mean when you first put the game in the CDrom drive and on then my computer when you look at the TOC size it will under 625(Most PSX games)
but they tend to stretch depending the meg size when you make a image of it..

At least so far with CDRwin..Nothing else..

When creating images, other temporary information is added to the image - stuff the program needs to add so it can burn it correctly. This can inflate the image size when it is on ur HD, but when you burn it, the temp info isn't burned so it is burned as the correct size. I would say all programs add this temp info to an image as it is usually required.

cdrwin creates BIN's. i can burn a BIN with NERO. its RAW DATA. put in an audio cd - see how many MB's of data it is. make an image of it with cdrwin. it should be the same. this is because the size of a data sector is 2048 bytes (bits? im 99% sure its bytes), while the size of an audio sector is 2352. the difference is in the error correction of the data cd, which is 304 bytes per sector.

http://www.disctronics.co.uk/technol...cdrom_spec.htm

that page has some of the basic info behind it. someone at cdfreaks has recommended a program that can write data in an audio way. I E 2352 bytes per sector, so that i can fit 800 mb avi's on 1 cd. i have yet to try it, but, of course, ima burn that real slow. i think its mode2cd2 or something like that. cant remember. post back if any of this doesnt make sense.
