The problem of standard vs non-standard disk formats came from drag and drop compilations before WinXP. I first burned disks in Win98, which only had native support for CD-ROM but not CD-R. Consequently the drag and drop method of disk compilation was left up to drive manufacturers to configure, and different brands had different formats.
Win XP has native drivers for CD burning, so maybe all disks made from the desktop with WinXP will be standardized, but I've never bothered to investigate. When I moved to a WinXP box, I found that some of my old disks were unreadable. It turned out that the unreadable disks were drag and drop compilations, which had a proprietary disk format exclusive to HP, the drive's brand in my previous computer. These "bad" disks required a reader from HP before they could be read, WinXP couldn't read them. The disks that I'd made to be " read on any computer", using the drive's GUI, were all OK. >From that time I've only ever created standard format disks through the drive's software rather than through Windows (because the next version of Windows might do drag'n'drop burning differently and I'd rather not find out the hard way ). IOW I'm speaking from personal experience and investigation. When I refer to "Drag and drop" compilations, I refer to dragging files onto the Drive's icon, or into the opened folder of the drive, and letting the OS take care of the writing method. I never do that these days (I always open the drive's GUI)and I attribute my good record of disk non-corruption to that precaution.
