Hey guys. I'm new here and best defined as a geek wannabe (although you'll see that classification might even be generous.) I have a Dell XPS M140 with 80gb hard drive. Picked up a Hitachi HTS541616J9AT00 160gb drive and thought I could swap it out. Here's what I did, and where I'm now stuck. Bought TI 11 and a USB enclosure. Installed TI, placed the new hard drive in the USB enclosure and cloned the 80 gb hard drive to the 160. I niavely thought I could place the newly cloned hard drive into the Dell and I'd be ready to roll. Unfortunately, when placed into the laptop and booted up, it begins to show the Windows start-up and, just before it gets to the password/log in screen, it goes to a blue screen and locks up (I'm running XP btw.) Figuring the cloning didn't take, I thought I'd erase the 'cloned' disk and try again. However, when I place the 'cloned' disk back in the USB enclosure, the computer doesn't acknowledge it. Is this because Windows is seeing two C drives? I turned to this forum for help, but after reading a ton of postings, I found myself even more confused. Mostly because I now know about the difficulty with swapping out Dell hard drives that have the Media Direct button (which mine does.) In short, I'm not sure how badly I screwed this up, or what steps to take to remedy. Right now, I just want to get back to square one, get my computer to recognize the USB enclosure, erase the disk (yes?), and get to a point where I can approach this correctly. I'd be grateful to anyone who can point me in the right direction. Thanks in advance for any and all recommendations.
