I've been searching for hours today and I just wanted my new 400gb SATA Seagate to work I was even started singing the "get perpendicular" song when it came! Alright, here's the problem like many other A7N8X-E users have faced in the past: I've had recently fresh install of windows XP Pro running for a few months now, and I installed the SATA hard drive. It shows up under the SiliconImage boot screen (the small one after the main POST) but once windows loads up, nothing shows up. I have installed the driver for the SiliconImage SATAraid software, and it does not show the little yellow question mark in device manager. I have found many threads with this problem, but no clear solution. Most of the threads were circa 2005, so I'm hoping that somebody knows a solution. Please help! I want my storage!
