You knew that didn't you?

OK, for the most part any model with the same size and interface will do but if you were using a bundled Roxio that app may be tied to that drive. This could confuse the issues so for the uninitiated you replace same with same.

HOWEVER I no longer replace such drives but whip out my USB DVDRW (under 30 bucks) and let them try that. This drive will be useful later on other computers.
