You mean the USB hard disk is working properly but logs that output or
you get the errors and the disk is not detected at all?
You can make a quick test: run " dmesg | grep [euo]hci" in both computers to
check what USB module is in charge of the disk. There are some devices that
play better with old "[uo]hci" stack and have problems when using the new one.
