I have an HP dv6810us. its 7200 rpm and only has 160 gigabytes of space. I just bought a Western Digital My Book Essential 2TB external hard drive, at 7200 rpm; model: WDBAAF0020HBK-NESN. I have put ALL my movies, documents, music, pictures, and everything other than my programs and stuff that came with my computer. I only have 20 gigabytes left on my computer i was wondering how i could somehow turn my external hard drive into my internal hard drive....and how. any websites of videos that could lead me to the right place would be very helpful. i have used 140 gigs of space on my computer mostly due to the sims 3 and programs. please help!
