I want to connect my external Lacie drives to my MacBook Pro using an eSATA connection. However, I couldn't find any information on the web on which Express cards work with the MacBook Pro. Rather than purchase the Sonnet Tempo card that states it's OSx compatible but costs £70, I took a risk and purchased a card from STLab that looks identical but only costs £24 but doesn't state it's OSx compatible. It was a risk but I'm fairly sure all the cards currently available are the same card just rebadged but I'm not sure if they have different firmware. When I plug my card in, the MacBook Pro recognizes it strait away but nothing happens when I plug the cable into the Lacie drive. Buying the cheaper card was a risk and I don't mind buying the more expensive Sonnet Tempo card if that's the problem but clearly I don't want to if the problem is not to do with the card. Anyone know if the problem is the card or something else?
