I hope someone can shed some light on the issue I'm having. I have a couple of 32gig usb drives i use to watch videos on my sony blu ray bdp-s185 with no trouble. i wanted a stick with more space so i picked up a 128gb drive and it was working initially but as soon as i went over 25gb or so of storage, the bluray player stopped recognizing the drive. If I remove some content the player sees the drive again. Is there any reason why the player would stop recognizing the drive when its not even close to being full? Thanks is advance.
