And an NTFS file system can only live on a hard drive. Indeed, you could have a system with both NTFS and FAT32 file systems. What kind of system is that? :) Since there are so many machines involved, it should be pretty easy to isolate what the real problem is. There has to be something else that is in common between all of the machines that can't read the disks. Or, between all of the machines that produced the unreabable disks. For example, perhaps one or the other of those two groups of machines have the same brand of CD drive. Or operating system. Or CD burning software. Maybe it is the brand of CDs. A pragmatic approach might be to try to regenerate the CDs. You say the CDs produced on the NTFS systems CAN be read on the FAT32 systems - just not the other way around. So, take one of the CDs produced on the FAT32 systems, copy it to a hard drive (on an NTFS system) and then burn a new one. This would be a lot of work for 70-80 CDs. :) But it would give you a set of CDs that you could read on any system. And going through the process (maybe only for a few disks) might give you some insight as to what is really going on. As for your last question: "If you would kindly explain what software you use and a step by step process you use to burn a CD on a FAT32 system that is readable on a NTFS system. I have several different programs for burning CD's including Nero Burning Rom and would be most happy to purchase software to accomplish what you are saying is possible." I'm afraid that I haven't used FAT32 (or FAT16) in ages (except on floppies!). But, except for a couple that have gone bad with age, every CD I have ever produced is readable on my current system, an IBM Thinkpad running Windows XP and formatted with NTFS. This includes CDs created on Windows 3.1. I have always used the Adaptec software in the past. (Though I use various software now - including the built-in Windows XP CD-burning support and IBM DLA.) I've never used the Nero software, FWIW.
