Hi, im having a problem with a SD TO CF TYPE 11 adapter. My C70 / C80 will not read, please does anybody have any ideas.
Thank you.

Are you referring to the Compact flash card to download upgrades and store backup's, if so these are difficult to make compatible and even more difficult to get hold of.   Can you elaborate on the type of adaptor?

Can you give some details of the problem?
