Other than keeping a zip disk in this USB zip drive, is there anyway to tell the system that the device is a portable device and that it may not have a disc in the drive? Does not make sense checking a portable media device for being ready on a daily basis? May 17 23:50:01 www kernel: Device not ready. Make sure there is a disc in the drive.
