As per my other post, I'm one of the unfortunates who got hoodwinked into buying the Western Digital EARS 2TB drives for the DNS-323 before stumbling upon this forum to see the sticky that they are not currently supported.
I think I may have a partial solution though:
I have a 1GB Western Digital black drive that does not use advanced formatting which can be used in bay 1. When the drives are being run in standard mode does the DNS-323 only create it's additional partitions on drive 1 or does it do it on both drives?
If it's only on drive 1 I should be able to run the EARS drive in bay 2 with the jumper in place to offset the sectors by 1, thus eliminating any problems for the time being.
