I recently installed a Maxtor L080L4 Hard Drive into my PC. It is plugged into a Maxtor 133 PCI Card. I also have two other Maxtor Serial ATA 80GB Hard Drives on the machine. When I go into explore, through start, the new hard drive does not show up. However, when I go into control panel>system>hardware profile, both the card and the hard drive show up and are said to be working properly. I installed all the drivers necessary for the card and formatted the hard drive. Also, when I go into control panel>administrative tools>disk managment, the hard drive shows up and if I left mouse click on the drive and hit explore, it then shows up in this explorer. However, it still doesnt show up when I go left mouse click on start and hit explore.
