The follow post I made on iHub describes my confusion, but rather than read my BabbleSpeak and get confused, let me try an explain what I discovered, as I thought as you mentioned, once a CD-R was written to using the software included as part of Windows XP, that once the writing was finished, and I removed that CD-R from my CD-RW drive, I thought it became read-only. I was wrong for my case using Windows XP. I filled up only 10% of that CD-R and later after removing the CD-R from the CD-RW drive and actually shutting down Windows and all the way to a power off, I was able to later write more onto that CD-R eventhought I thought I needed a CD-RW disc to do that. The way I see it is that a CD-RW disc is like our harddrives we have, or like those 3½ & 5¼ floppies that we are able to fill up and delete stuff and fill up again and again. But that I mean we are able to re-use the same physical locations on the harddrive or floppies over and over, either by deletions or a re-format. The CD-RW disc is like that, in that if its 99% full and you are able to delete lots of stuff, you can then make available surface areas for new files that had files on them from earier writes, but you just now deleted them. The CD-R disc is a one-time-write-on-a-surface. I'am guessing that you can delete a file on a CD-R, but while its now "gone" you cannot reuse that surface that held it. So my experience, you can write to a CD-R many times in different sessions using WinXP's buildin software, but once the total surface has been written to you cannot delete file to free-up space, as you can using a CD-RW disc. With CD-R discs very cheap versus CD-RW discs I can't think of a reason to buy the RW types. With this being true, the above, the writing speed for a CD-R may be x10 that of a CD-RW when the CD-RW disc is being written to an area that was written to before and been deleted and then if you understand what I just said, then WOW :o) Maybe someone can describe situations needing a CD-RW disc.
