...but I did have success with the setblocksize util!
I've put together a very slightly modded version of setblocksize

many thx, Allan Houston
i had the same problem and with your great hint, it was possible to change the block length from 512 to 520 and now the ethers NAS don't tell me anymore "not supported" not it's present and I can use it. 1000 thx
cheers
