This is probably stupid but... I installed a WD 80G SATA drive in my PC. It shows up in the device manager and says its working properly... but it doesn't show up in "My Computer". It is connected to the SATA 1 port on my ASUS P4P800E MB. I have 2 HDs on my IDE1 and 2 optical drives on my IDE 2. Any thoughts... help. Thanks.
