Scratch that. Last night I tried to transfer a dat using the 671. It seemed to record fine, but I could not play the file back or cue/rew. Attempting to playback produced E7, media format is f'ed up message. Works fine with the 64mb card they sent with it. Oh well, back it goes. I'll guess I'll go with the kingston 45X. I'm glad I found this out at home.
