Jaledu,
3.8G is the correct formatted capacity. Try formating the card while the R-09 is attached as a USB drive (Trancend card in the recorder attached via USB to the computer, open Windows Explorer and format the card from there). Always works for me & eliminates any third party reader variables.
dlantelme,
I flubbed a few at first with the recorder in my pocket when it paused or stoped inadvertantly until I got the hang of using the 'hold' switch religiously. It can be tricky to un-hold, adjust levels, and re-hold without looking, being careful not to pause or stop without looking. If you can best-guess your levels and start rolling then lock everything with 'hold' before you get back to your seat you're golden.
A small square of black gaffers tape will black out the beacon completely and still allow the transport controls to operate. The backlight display is still a bit bright, but with the exception of the mic/line-in cable, the recorder will looks pretty close to a cell phone without the red light. I pulled out mine out of my pocket (in it's cell phone case) at a string quartet concert at a church last week to check levels and the woman next to my girlfriend said 'oh he got a call'.. she told her I'd call 'em back later.
