Hello!
You should install and run the NAS Navigator because it gives you uncoded information about the status of the device!
You said that you created a RAID1-Array and well that takes a while and the Info LED is blinking until the build is finished!
Quote from the manual:
"While the array is being built, file transfer speeds will be slower than usual. It will take about 6
hours per terabyte to build the array. The Info/Error LED will blink amber while the array is being
built. Do not turn off the LinkStation until the array is finished.
When the build finishes, the Info/Error LED will stop blinking. Your RAID 1 array is now complete and
ready to use."
Regards,
Guido
