So I have two bad hard drives from an old computer. Their only real problem is that they can't boot. I had the one (a 12gig) as a slave on my mom's computer for a while. But the other one (a 80gig) didn't work with hers. It crapped out first, so at first I had the 80gig as a slave to the 12gig. Well, when replacing a network card, I didn't install the driver first and screwed up the 12gig too. That's when I tried slaving them to my mom's computer. Anyway. Of course I have a new computer these days. But I've been averse to messing with its guts much while its under warranty. The warranty expires next month so I figure it might be a good time. I had access to the 12gig stuff on my mom's so that's not a big deal. So I put in the 80gig (and it was weird. The hard drive in there doesn't use an IDE cable. It has some thinner cable connecting it to the mother board. You techies probably know, but its new to me. But the motherboard had a spare IDE slot which I can only assume is for slaves. As there wasn't any spare slots open in the one connected to the DVD-ROMS as I'd assume there would be since most computers today are built to be ready for upgrades like this, anyway) so I boot up with fingers crossed, and it seemed I'd guessed right. Windows loaded okay, detected new hardware, realized it was a hard disk, and that was it. I go to My Computer and it's not there. I reboot and it's not there. There doesn't seem to be any problem, it obviously can detect it. Any ideas why its not showing up?
