I have just replaced one of my disks in my D-Link DNS-325 and formatted both; they are set up as standard volumes. One is 1.5TB the other is 1TB. I can see them listed in various places, but they don't show up at all in 'Account management' -> 'Network shares settings'. I can see them under 'ISO Mount Shares Settings', bizarrely. I have tried upgrading to the latest firmware I could find: DNS-325_fw_revA_1-05b04_all_multi_20161118.zip, which went well, but no change.
Is there anything I should have done on the way?
