It still doesn't work. So something is wrong. Options > anyone? What else do you have connected to the string? If there's something else, and you obviously have access to a second controller, try using both controllers, with only the tape connected to the one controller. If that doesn't work, consider your drive options. This was an Exabyte 8505, wasn't it? Exabytes used to have millions of drive options, so much that hardly two drives were the same. Maybe the drive does something that the driver doesn't understand. Greg
