So, whats differant from CD-R and CD-RW?

[TechDude]

Besides cd-r can be written at 16x.

I just dont see a differance. Both CD-R and CD-RW can be reformatted and thus you could burn stuff on it again. And in NERO i believe you can save your progress so next time you wanna add to the cd, you could open your progress and drag more files into it and burn.

No, you cannot refromat a CDR media and use it again. CDR is burn only writable, not Re-Writable media...

The difference is that CDR medias cannot erase data that's burned to it. CDRW medias are very handy when you use a packet writing program such as Direct CD where you can drag and drop data for saving as well as deleting. With CDR media, you can only save in a single session or leave the session open to add more data at a later time. You cannot delete data...

Dude: You are partially right. You can burn data again to a CDR but on UNUSED space. You can't write on space already used up and you most certainly can't reformat.

As NDC says, if you leave the session open, you can write more data but you loose a lot of space if you do multisession CDs.
Around 15-20MB is "lost"-used to redo the patrician tables/table of contents. CDRWs are much better in the long run- cheaper, convenient and last a long time (1000 re writes, which is a lot, believe me). I have one CDRW which I use to transfer stuff from here and there. Its my first one and I started using it in 1999 and its still going strong and has been used all of 389 times. Probably last me the rest of the decade. At that time it cost $25 EACH, today its about $2 for a good brand.

Doing that multisession thing is tedious and time consuming. Go the CDRW route.

I think I mentioned this already? ;)
