Until a couple of weeks ago, I would have said the Lexar firewire CF reader was an excellent product. Then I bought 3 Transcend 1GB cards, since the one I had worked fine. The new Transcends would not mount reliably—sometimes they would, but mostly they wouldn't. I got no reply at all from Lexar's tech support. I got a shrug from Transcend's phone tech support. Fortunately Matt at mydigitaldiscount.com took back the Transcends and exchanged them for Ridata 1 GB cards. They work just fine in the Lexar reader. So now I'm a Ridata fan and I'm keeping my fingers crossed that they don't change controllers or do anything else that will cause an incompatibility with the Lexar reader.
