Gigabyte GA-A75-UD4H Raid Fails When USB Device is used

[Ricardo Montelban]

Hello,

Over the last couple of months there has been six or seven occasions where the RAID 1 array on mysystem goes “critical” when I plug a USB2.0 device in to a front panel USB connector. I have seen thisoccur with an iTouch, USB thumb drive and an Android based cell phone (Motorola Razor). The “critical”message appears the second that the USB device is inserted - nothing else is going on with the system.The array rebuilds with no issue.Are you aware of any issues where inserting a USB2.0 device can cause the RAID controller to lose oneof its drives?The system has two 1.5TB Western Digital 6Gbps SATA drives (port 0/1).AMD RAIDexpert reports version: 3.3.1540.13. Not sure if this is a version number for the RAIDfirmware or the control software.Thank you.
