Hello, The drive is healthy (SMART OK) I played with hw.usb.umass.throttle, with value 10 and 100. It slow down the USB transfert and decresase the %system load ~10%. But I kept the normal value (0), the system succeed to dd 10GB to the USB drive without crashing If it reoccur I'll rebuild a kernel with USB_DEBUG, and this thread will be updated. Thanks for your support Hans.
