Hello Arnd,
I discovered the hard way that not all kingston cf 4gb are equals. When reading the back label, I saw differences in what seems to be a revision number.
I have here 001.AOOLF 005.AOOLF 006.AOOLF 018.A00LF 030.A00LF
They all have the same front label, except the 030 series which has a slightly different front label. I have attached the two labels.
I also have white (no label) CF 4G cards that we buy from pcengine.ch
I send you in separate messages the results of flashbench on them.
I am sorry I do not remember exactly the sequence of commands to execute, so feel free to ask for more info.
