Hello, I am completely newbie as for intalling any hardware in my computer.... i have never intalled HDD myself but I want to add additional hard drive. Do I get all the neccesary cables(like power cable / ribbon cable)? or are they already there in my computer? or do i have to buy them separately? my computer is dell 4600 series. just opened up my computer. I think there is data cable(ribbon cable) but i couln;t find any power cable... read the manual but it just says 'connect power and data cable'. noothing about where to connect and how to connect... thanks in advance for all your help...
