    The following suggestions may help if you encounter problems with Disk Benchmark. • U se Windows Device Manager to check and verify that all drives are visible to the operating system. • I f drives are not listed, check the connections between the drive enclosure and the RAID controller card, and verify that all drives are fully seated in their bays. • M ake sure that the enclosure is powered up and has completed its self check before booting your computer. • R eboot your system any time you make changes to a RAID group (after the RAID group has been rebuilt). • A s a last resort, you may use the ATTO Boot Configuration Utility to low level format a troublesome device. However, this erases all information on the disk. • H ave you partitioned your drive, and then activated that partition? • Did you format the drives for use with your operating system? If problems persist, contact Sonnet customer service.
