What firmware were you running initially? 2 TB drives weren't supported until 4.1.7.

As stated above: 4.1.15-T2

If you can't access them with Seatools or Lifeguard then its possible the drives somehow got locked. If they are accessible, then perhaps either zero them or delete the partitions before you try again.

Just before I tried reinstalling the last time one of the drives was recognized as 2TB, that's why I restarted the NAS again to make it synk. But no access after that. I will try again now.

When you insert one of the 2TB drives on your NAS, does the raidar see if you have disk or does it say no disk detected?

Previously, if connected/inserted at boot, the blue light is slowly blinking and there it just stays without booting upp fully.

When you have connected it to a PC, did you use a disk diganostic tool like seatools or WD lifeguard?

As I noted above, the drives are not - at all - being found on a PC. So therefore I cannot run any type of test.
