I bought a card, and I will install it tomorrow, which will effectively give me two SATA connections- one internal, one external. I might just use the new drive in the system and set the ex hd case aside for now. The problem was no SATA compatibility with my mobo. I don't know what I was thinking, either- the old ex hd case uses ribbon cables, too, just like the hd I have in the comp now. Most of what I know about hardware is a couple of years old, and I haven't kept up with all the advancements, obviously.
I use Norton Internet Security 2006, and to be honest I have no complaints with it. I've never had trouble configuring it, and Norton has never let me down by letting any bad guys through. Norton is a resource pig, but my hardware is good enough that Norton doesn't slow my computer down. I used to use Norton because all the OEMs that I supported came with it already installed, and I needed to know how to fix it. I use it now because if I try to uninstall it and replace it, bad things happen. I have tried the Symantec tool, and a few other tricks, but this is an old XP install with four versions of NIS overlaid on top of each other, and I'm sure the registry is a Symantec mess. To switch security clean, I would need to reinstall the OS, and I'd rather wait and do it fresh with Vista.
I need to upgrade my motherboard first, because it's maxxed out with a gig of ram. For XP and the way I use this computer, my cheap graphics card is adequate, but I'll need a new one for Vista. At that point I'll decide to bump this computer down to the kids and put together a new one with one of the new AMD processors and even USB ports I can depend on. By the way, for anyone reading through this drama that hasn't fallen asleep, or searching this next year, you get USB2 with the MS service packs, not hardware. If Windows does not have the service packs applied, you can use USB2 equipment and you will get USB 1 performance, period. Also, until you install SP1 on XP, Windows will not recognize a drive over I think 120 gigs. (Someone correct me if I'm wrong on the size.)
Thanks for the help, and I'll let you know how the card and new drive are working tomorrow. I never thought I'd use my first computer's 40 gig hd. Then I got this one and thought I'd never fill 80 gigs. I think this new 320gig Seagate will last about a year, then I'll need more. If this were paper, I'd be killing a forest.
