=== Raid Setting===
Please read [[Raid Instruction]] firstly. You can freely choose the four RAID modes supported by NASPi Gemini by setting the jumper cap. Strongly recommend to use the same brand and capacity HDDs when use RAID Mode. ＊'''Warning''' : Please backup your data before setup and switch, otherwise you maybe lost your data. 1. Inert HDDs to X885 shield and fix it. 2. Please connect the X885 to your PC or Raspberry Pi board and '''keep power on'''. 3. Switch RAID mode* Set the switch button to your preferred RAID mode(PM/RAID 0/RAID 1/SPAN) as per the RAID illustration table.* Press the '''SET''' button for about '''5 seconds''', and release it till the blue LED indicators starts flashing.* After RAID mode changed, please confirm that the PC can recognize the disk(s) properly and shows the right capacity. or you can run the fdisk -l command to view the hard drive on raspberry pi OS when you connect X885 to raspberry pi board: fdisk -lYou can found two hard drives if you select 'clear raid mode'(this is PM model) or You found only one hard drive if you select the RAID0/RAID1 model 4. Set CLEAR RAID mode (PM, factory default setup) * Press the SET button for about 5 seconds then and release it till blue LED indicators starts flashing.(The two blue LEDs will flash at the same time, if not at the same time, it is unsuccessful)* After above processes, the setup for CLEAR RAID is done. [NOTE] Once you set the RAID mode successfully, you need to partition&format&mount the hdd/ssd, so that it can be recognized by your Raspberry Pi OS. please refer Refer to [[How to View/Partition/Format/Mount HDD/SSDConfigure RAID Setting]]
