Since the health of the drive is ok as per that test, you should not worry about this, the Smart event is a continuos check of the drive that is done, maybe a little or single error in the data transmitted was present which could be triggering this error.
What do you see after clicking "Suppress SMART event"
Thanks for the link I'll check it out
Yeah I think the drive is fine for now, had this pc around a year now and had no problems
When I click 'surpress smart event' it then says your system is functioning normally and the drive shows a green tick but usually goes back to the previous status on reboot
I'm pretty sure I don't need intel rapid storage technology running anyway, as I don't think my pc is RAID configured, so I've stopped it at startup but not uninstalled it and boot up and access to the drive seems to be just as quick!
