A CD-ROM is read through MS extensions as though it were a : 650-MB HD in FAT16. I do not know whether the slack space is actually : recorded as zeroes - but I suspect that it is from some very rough tests : I ran. : : Your assertions are logical, but I do not believe that MS employed such : logic in designing MSCDEX. MSCDEX has no relevance in this issue, although the recording software does... I refuse to believe that the ISO 9660 standard was designed to allow for the limitations of one particular piece of software that would be used to read it. The issue is NOT how the data is accessed - it is entirely about how it is stored on the CD. I have a strong feeling that MSCDEX doesn't even try to emulate a HD with a FAT. There is really no need for it to do so, since it works on the same level as networking software where it provides only file level access. Try to chkdsk a CD - if your theory was true it should run and then show some statistics - instead it returns "Cannot CHKDSK a network drive." Regards, Mark Griffiths.
