I have set up my ss4200e with the latest firmware. It has created a raid 5 and I have copied files to it without problem. However, if I reboot or turn off the ss4200, it never boots up again (I get the flashing power light). I have to press the reset button while also pressing the power button to get it to boot properly (I have read that this makes the ss4200 boot from the DOM and not the sata drives. However, once it is set up with the raid 5, surely it should boot from the DOM anyway). Hope someone can throw some light on this.
