I was looking to replace these two drives in my computer. These are the drives I had in mind: CD-RW Yamaha Lightspeed Plextor (I wish it came w/ the Nero software) TDK DVD Cyndyne Pacific Digital Any thoughts or recommendations (I am having more trouble in the DVD area)? Also, what is the difference between IDE, EIDE, and ATAPI? If it matters I have a DEll XPS T500 (about 2 years old). Thanks in advance.
