Question... Why can't you use a CD-RW for a Boot CD Rom ? Or to create a Music CD to play in a home or car player ? I can burn a Boot CD and a Music CD just fine, But when I try to use it my computer it won't boot from it. The same with a music CD, It will play on my computer but not my home system. How is a CD-R made different from a CD-RW ? It is because you can erase a CD-RW , The structure of it ?
Thanks for all input and help !!😀
 
I'm not sure why you can't boot from a CD-RW. Can you boot from a CD-R?

CD-RWs use different materials from CD-Rs that allow them to be erased. This gives them different reflective properties, which some CD players may not be sensitive to.
 
If those CD's played in your stereo, they wouldn't be able to sell the big soundcards and speaker systems they're making for your computer. Don't pay any attention to me, I can't answer your question.
 
most cd burning programs use packet writing when using cd-rw's that requires the cd-rw to be formatted first before anything can be writting to it. this formatting of a cd-rw is why it cannot be bootable. a regular CD-R doesnt require prior formatting and thus can be burned with files to create a bootable cd-r. and the reason why some home/car stereos cannot read cd-rw's is because of the lower reflectance in the chemicals cd-rw's use. the laser pickup in the cd player just can't pick up the low amount of laser being reflected back to it. most newer home/car stereos can support cd-rw's but you should check to see if it specifies that it can read cd-rws.

the only reason you want to use cd-rw's is for backing up data, which you will be adding or changing the contents from time to time. this beats burning a cd-r every time you want to change something. they are also a lot more expensive so that makes them inpractical for every day burning.
 
Thanks jvang125 for taking the time for that very informative answer. I was'nt to pressed to use a CD-RW for a boot disc . More curious than anything else.
That's mostly what I use them for anyway, Backing up updates and files that change now and then . I bought up a lot of them when a local chain store went out of business.
More than I'll ever use , But it's nice to have them around. :moon:
 
Actually PrincessGuard is correct as to why a burned CDRW (not using a packet writing software) doesn't work in some (most) home audio or car audio players. Just the wrong color for the read lasers on most non-computer readers.
 
Yup, it was just recently that they started making car, home and portable CD players that could read CD-RWs and play MP3s as well as CD audio. Previously, they were just for computers. I'm not sure they're still very reliable even for computer backups. I was on the Adaptec (prior to them breaking out that div. into Roxio) CD recording mailing list for a while and it seems like all there was was complaints about losing data from packet-written CD-RWs...
