Hi, yes, can't write to it, scan it, just look and the files in it. My original USB was a Kingston DT50 and for the last 6 months I keep getting kernel errors, but i fixed them by replacing bzroot. And today i got that error msg, and i know that the USB failed, but the funny part was that i went to buy a new USB and that one failed also, same error. Any way it works now, I've replace it with a 3'rd usb that is used, so hope it will keep me for 1 year :D.
