I bought a cheap SD card (16GB) supposedly a Kingston, but data shows as a Ricoh. Anyway, regardless of whether I drag and drop in RB, Original, or with a holder in the slot of my laptop, it writes some of the files ok, and most of the tracks come out with corrupted titles. Ive formatted and re-formatted, etc. I figure it's just a junk card. I got a full refund, so no harm, no foul. FYI (BTW the device is a Fuze V2).
