How many times do I have to say that I tested exactly what you said you tested (granted, we're probably using different size and brands of usb thumb drive), and couldn't reproduce the problems at all? I plugged the memory stick both into a powered hub, and directly into the beaglebone. I used the exact tar and rsync commands you did, using both nfs and ufs-on-sdcard as the source drive. No errors, the copies always completed. I think it's looking increasingly like you have bad hardware. -- Ian
