Re: Snap 2200 - Mirror Problems.
The 500gig drives taxes the power supply pretty hard. If you look at the current draw (x2 for 2 drives) and see if it's exceeding the 4amp 12v power supply. The MB will draw around 1 amps including the fan. I know it does on the startup surge.
Another issuse may be heat. I would setup a external fan if you have the case open. When open up the unit does not draw the air to cool the MB properly, with the drives heating it up. And verify the fan is working properly. With the larger drives it would not hurt to add a higher cfm fan. Snap used a low noise low cfm fan in these units.
