The day has finally arrived. My 80G WD800JD OEM HDD is full. I pull the cover off my Dell desktop and confirm that there is another slot available for an additional drive. Should I add an identical drive, or does it matter? What is the short unused cable coming off the existing HDD? Is this some sort of jumper to connect a second HD?
I take it is a sata drive, so the good news is you should be able to use pretty much any and all drives that are on the market right now. The only limiting factor might be your operating system and specifically 2+tb drives. So to be on the safe side, buy something < 2tb in size and it should work.
