I will be replacing a large quantity of CD's that were lost recently, and I was planning on buying a RW drive anyway. I have heard that IDE RW drives have difficulty synchronizing with IDE CDROM drives, causing compromised CD quality. This is supposedly diminished if you download to a hard disk and then to the RW drive. What is the difference between IDE and SCSI? What type of drive would you recommend for this type of application? Do i need to download and then write to disk?
