And yes, this time I've read the manual and tried *everything* it has suggested. So what can I try next? It doesn't seem to any longer like my 4gb cards - I've been using them all day and its only after I've changed the batteries that all this began ... And yes, I have tried different batteries! Oh, it took about 10 hours to transfer 3.2gb of text, audio books and music last night! I have also tried several 4gb cards and formatted them all. I have also tried several 2gb cards and formatted them all. Tried a re-boot; a different cable; different USB port; unplugging all other USB devices; Windows XP Pro recognises it has been plugged in but says there is an error and its an unrecognised device. NB All my other USB devices, and I have many, work. Having tried **all** the things suggested in the manual, I'm at a loss! Suggestions please ... or have I a pooped BP? I love the device and when it works well, it works very well .. but the salient word is "when"!
