I purchased a WD 120gig HD from zipzoomfly.com I got it hooked up and everything it was even being recognized for a while. I hooked my old secondary HD up to the IDE port that WAS hooked into my CD burner, to transfer files. The new HD stopped showing up. Now my primary HD is almost completely full and my PC isn't recognizing the WD drive OR my CD burner. I have no clue what to do and it is extremely annoying. For the record I'm new at this switching/installing drives stuff so I have no clue what to do. PLEASE help me.
