Default Utility needed to Verify ISO image with burned disc

Can you point me at a definition of CDROM .ISO files?


Easy: the definition follows from the intended usage:

ISO file when copied to the media sector-by-2048b-sector should
produce the identical disk. (Which implies that some disks cannot be
mapped to ISO files - they may contain errors in 2376-byte (sp?)
sectors correctable during translation to 2048b-sectors, etc.)

All bytes matter during copying. So ISO files produced by reading a
disk must be identical.

Hope this helps,
Ilya

P.S. I use readcd to produce ISO files, cdrecord (or "flavors", like
dvddao) to burn them.
