So I have 2 DNS 320 A2 NAS, one with 2 HDD in RAID 1 config and anohter with only 1 HDD also RAID 1 configuration. So I needed more NAS drives and bought two new DNS 320 to find out they were the model (B2), however when I insert an old HDD with data on it which is read by the A2 chipset, it does not work on the B2 and I have format it in order to use it (which I cannot format since it contains important data).
Is the A2 chipset no compatible with the B2?
Note: I already tried updating for the Firmware 1.02 or trying various different disk types but the amber light shows on the B2 while if I insert the same the HDD on the A2 it works fine.
Thanks
