I have read the posts on IMSM 8.9 RAID failures with Windows 7 Pro x 64 RAID 1. I too experience this, but only when I used the Logitech Webcam Pro 9000 on the system, and then the probelm is severe - can not boot and have to use a backup image set to recover. As long as I don't use the Logietch webcam I have no problem. My system: ASUS P6T, 12 GB RAM, EVGA nvidia 250, WD r03 enterprise drives.
Has anyone else experienced these failures with the Logitech Webcam? Or failures that disappeared if a device was removed?
