So I have a new PC system up-and-running now. There were a couple of bumps in the road, but other than that, everything went smoothly. I bought a Seagate GoFlex External drive on sale at newegg; it was a discontinued 1.5TB model. Seagate now makes GoFlex external drives only in 1, 2 or 3TB versions. I got mine for US$99 to-the-door. I bought it to save my vast MP3 collection, photo collection, and videos and documents; but sometime during transferring all my files to this USB 2 drive I realized that the USB port connection was nothing but an annoying bottleneck. I wondered what was inside the sleek futuristic case. I posted a message at the Seagate forum asking about possibilities of cracking the case and hooking directly to a SATA slot on a motherboard with SATA power clipped from my ATX power supply. My post was avoided like the plague; you couldn't discuss Hatcheting open a fine Seagate product; nobody replied to my post for days. The night before I rebuilt my PC system, I held the external drive in my hands, then went and got a screwdriver and some other small tools. With intrepidity I carefully broke open the case. The case was assembled around the drive so you couldn't plug conventional SATA data or power cables into it; but I could clearly see SATA interface connections when I removed the USB 2 adapter. Long story short; I hacked this puppy open and was rewarded with a Seagate Barracuda green 6Gbps 5900 rpm 1.5 Terabyte hard disk. My two Western Digital SATA Raptors were immediately demoted to drives [D:] and [E:] and I proceeded to build my system on the Barracuda. New problem: my operating system had recently been upgraded from Windows XP. I did this with a Windows 7 upgrade disk. Upon going to re-install my W7 OS, I chose custom install and laid it down on my new 1.5 T Barracuda. I was asked for my Key-code, typed it in, and it was declared invalid on the grounds I could only install W7 as an upgrade and not as a clean install. I had hoped it would recognize a 'System Reserved' partition that still existed over on the WD Raptor where I had W7 before. This didn't work out. Long story short; I had to go through all kinds of hassle with my operating system software, online help guides, Microsoft help agents based in South Asia ...and even a REGEDIT by way of the command prompt in ADMIN mode to finally get my system properly activated again. I was worried there for a while. Now I can relax and look forward to the hours of waiting time for Valve Steam to download all my games again. By the way: I love my new system; and remember, I didn't build it to out-perform my old one... I was forced to build it because my old one broke down.
