Work with Cached Drive

hi,

my cdrom is a kind of cached drive.  i heard
cdparanoia is not safe on the class of cdroms.  so i wanna ask, what do
i do?  does the cdda2wav help?

on the other hand, i still has anotehr CDROM ( actually a DVD writer ),
it's a ASUS DRW-1608P2S . where can i get know wheter this drive is
cached or not?  since i am not equiped with a Windows , so i can not
run EAC to make sure of it.

thanks.
