Have you connexted them to computer with card reader?
If it works well, first, the CF back-up to computer and format them.
After that retry it.
If it doesn't work, the ND2700 is bad.
If so, you should take A/S.
Transcend CF 16GB 133X의 메모리를 카드리더기에 꽃아서 컴퓨터에 연결을 하시면 컴퓨터로 정상적으로 이동이 되면, ND2700 제품을 당사로 택배를이용하셔서 보내주셔야 합니다.

I've retested as you advised, still the same error.
But I wouln't say the device is bad as it works with all my other cards pefect (serveral Sandisk Extrem II, III, iV, Transcend 133x, sizes from 2 GB up to 16 GB).
Only the Trascend CF 300x don't work, so I assume, they have some different technology inside, which is not (yet?) supported by the ND2700 firmware.
