I'm trying to teach myself how to use mkisofs and cdrecord. I'm a little ahead on mkisofs, though that is like saying my verbals skills are better than my math skills because I can say "Ma Ma" but I cannot add 2+2.
Anyway, I wrote a script that uses mkisofs to create an iso of mp3 files from an m3u play list. The size of the iso file is 747200512 bytes. When I try burning it with gnome toaster, it refuses because it says the track is too large. The CDR is supposed to hold 700 MB, which according to my calculator equates to 786432000 bytes. So either there is overhead in burning the iso to disk or the CDR maker is figuring megabytes the way hard disk manufacturers do.
My question is this. Is there a way to determine exactly how large an iso file a CDR will hold? I looked at the man page for cdrecord and found options that will tell me about the recorder, but not the media. But I'm pretty sure Nero and Toast on other OS's will tell me how much space is available on the CDR.
There is overhead involved.
I use a backup program to create ISO images to restore my system in case of a bad crash.
The largest iso I can create must fit on a 700mb CD. Xcdroast on my system says that a track containing 699mb of data in an ISO image is 733413376 bytes ( = 716224 kb = 699.4375 mb) in size.
Your file is just a little larger than that.
BTW, my calculator tells me that 700mb (700 * 1024 * 1024 ) = 734,003,200 bytes.
