Good morning

I've just bought a brand new ND2730 and successfully updated to firmware 1.12, but incremental copy seems not working. I'm gonna explain what I do:

With Auto Copy on

1) Copy my CF card files into the ND2730: it correctly stores all files in a folder named with the date of shooting.
2) Take some extra photo on the same card.
3) Insert again my card into the ND2730 and it copies again all my files and not just the new ones; moreover it stores my files in a new folder named with the date of today. If I repeated the action it would put my files in a new folder with the same name (today date) but with extension .001 instead of .000

With Auto Copy off

1) Copy my CF card files into the ND2730
2) Take some extra photo on the same card
3) Insert again my card into the ND2730 clicking on "Update" and get the following message:

CF ERROR
ERROR MESSAGE
No: 20B0
No2: 2054

I tried many times with CF Sandisk Ultra II / CF Sandisk Ultra 30MB/s / No brand CF / SD Sandisk. I tried formatting the ND2730 and launching the auto test but with no result. My camera is a Canon 5D Mark II

Could you help me, please? It's important to me
