8. Normal HDD mode for SR2000 is Ultra DMA. In the event of failure to work with EIDE connector, HDD will automatically configure itself in PIO mode 4 or with lower speed. 9. There is a 6mm Ball Bearing Fan integrated in the SR2000 to prevent overheating for 7200 rpm HDD. When two 7200rpm Hard Disks are installed in a very busy server, we suggest adopting a PC case with optimal design for overheating prevention in order to avoid PC or RAID crashes. 10.

Chapter 3 RAID Use After proper installation, the SR2000 can be considered as one HDD. Both FDISK and FORMAT commands have the same function on the two Hard Disks inside the SR2000. Some OS can perform self partitioning and formatting without going through the above mentioned process. After turning PC power on, SR2000’s two hard disks maintain synchronized operation unless one of them stops working. 3-1 Factory Default Buzzer On/Off switch ON Operation Mode Switch NORMAL MA
