AMD RAIDXpert system tray often displays an error of "Unknown Event". Checking the AMD RAIDXpert log shows the source as AMD Chipset SATA Controller - Controller 1 with "Error" under the Severity column and "Unknown Event" under the Description column.
I just replaced a drive that failed last week, but this message still appears nearly every day. Both drives are functional.
Does this mean that the built-in controller for the mobo is failing?
