The usbmon trace is: http://lockie.ca/1.mon.out The trace shows numerous -71 errors. These are low-level communication errors, caused by noise in the USB cable or something of that sort. In each case the system recovered and retried the failed command successfully. It's hard to say exactly what is causing all those errors. It could be a bad cable, or a bad connection, or a borderline component in the computer or the drive. It could even be caused by electromagnetic interference, such as a faulty fluorescent light fixture nearby. Alan Stern
