I'm using an almost identical setup to you (only difference is another dock manufacturer but similar design) without major issue via eSATA.
However, I have had some issues with recognition of a WD 20EARX under windows via eSATA, if hot plugging, which I haven't had with a WD 20EARS. Under those situations, I simply unplug and re-plug the eSATA cable and it usually rectifies itself. Of course you can't do this with eSATA and the Oppo.
I don't use USB, because I had stuttering issues when I first got the Oppo, that eSATA cured.
The only other difference is that I run the WD Align utility on my WD 2TB HDD, after formatting but before writing data, to align the partitions to the optimal value for these Advanced Format drives, although I can't see not doing that causing access issues.
I can't understand why you are having problems with an almost identical setup.
