I got my new seagate drive from seagate after my other one broke. I put this one in, I took off the pin item that was set to master, I plugged in the IDE cord, and the powercord. Now when I started the computer I went into the BIOS, and set the Primary Slave to ST311600 etc. The model # is something like that. I went to device manager and it's under HDD's. But in 'My Computer', it only shows 'C:'. How can this be? I've installed many HDD's before but have never seen this.
