DVD+RW on Superdrive

For a DVD/RW or CD/RW, typically they have to be formatted for use. This is a sizeable difference between CD-R, or DVD-R which don't have to be. I'm not sure how OS X does this. I do know that most other 3rd party burning apps (ex, TOAST) support this directly. I'm still looking to see how Apple deals with this.

ok your correct sort of about reburning stuff to a DVD+/-RW.

you can burn many times over BUT almost always your gonna have to erase the disk then burn to it. however there is a way to add something to the disk later without erasing it, by just dragging items to the disk using finder? I don't know if it can be done. but if you have a burning app like Toast, select to burn the disc so that its not finalized, and select multisession disk. then you can come back to toast later and add to the disk, and as far as doing it this way it doesn't even have to be an DVD RW, DVD R will work too

I was thinking of a true RW disc, which can be written to, erased and written to again, over and over. Not just a multisession disc. I've done this in the Windows world (a long time ago), but this is new to me with OSX.

Multisession typically means the disc hasn't been closed so more than a single write session can be completed, but only to the capacity of the disc. Once it's full, you can't erase and re-write. That can only be done using CD or DVD/RW media. I'm just ignorant on using this feature within the Mac world. I can load Toast to see what it can do. I've got an older version of it I hadn't planned on using.

no, verify just means after it finishes burning the disk, it goes back and checks to be sure there were no errors

i have toast but understand that you cannot do session work on a dvd-rw. only on cd's. i wish you could. if someone disagrees i would love to know how you can. the point of rw is that you can reuse the dvd many times.
