I just bought a new iBook G4 with a Combo Drive. This is my first Mac and certainly my first computer without a floppy drive. When I asked about prices for an external floppy drive, the guy at the store said that I should try using just the CD drive first. He explained to me that using CD-RW's was just like using a floppy disk. This is an example of what I want to be able to do: Save DocumentA and B At a later date, add DocumentC Modify DocumentB and delete DocumentA At a later date, create DocumentD and add it. Can I do all this and still keep DocumentsC and D, and the modified DocumentB? Or do I basically have to erase the whole disk and overwrite all existing documents if I choose the add or modifya document at a later date. I write many papers and the ability to add, delete, and modify documents is very important to me. I was not aware, before I bought the computer, that there was a difference between CD-RW drives and DVD-RW drives, other than the type of disk used. I realize that I could just as easily save and do all that on the hard drive alone, but I rarely finish a whole document in one sitting and I want to be able to backup my work. If anyone can explain to me what to do, I'd greatly appreciate it.
