When burning a file to CD, do most burning utilities read and write to the end of file or to the end of the sector? If I wanted to minimize transfer of slack space contents, do all utilities (Roxio, Nero, etc…) work the same with respect to file copy vs sector copy? Is there a reference which covers this topic?
Thanks in advance.
the CD uses its own file system (ISO 9660 or juliet) which uses the concept of sector, cluster, ..etc. In my understanding copying a file to a CD still copies the file slack space. how much of the sclak space is copied over depends on the cluster size used in the CD file system.
ISO9660 uses a cluster of 2048-byte which seems to be universal, but other sizes are permitted.
A good reference on ISO 9660 should give you more details.
