RE: [TCLUG:20847] Very stupid CD Burning Question:

Thanks Phil; I had figured it was something like that and I wondered what
sort of overhead I was looking at.

I've got a script that creates an iso9660 image every night as a bootable
linux image, and I was starting to hit the outer limits of what would burn.
According to my calculation, I should have been able to burn 681574400 bytes
on a 650MB disk, but my ISO image clocked in at 662517760.  I wanted a
number to put in my script that errored out and deleted the image if it was
too big to actually burn, so I thought maybe there was a specific number
that I could be sure of across all media (obviously, someone selling disks
labeled as 650M that would only hold 500 would be in bad shape).  Guess I'm
not going to be able to get that last few megs out of it.
