David, This is a copy of the mail I sent this morning declaring this problem as solved. You had right, it was a connectivity problem. Many thanks for your reply. E. Soriano I feel this problem raised because I was using a wrong SCSI cable between the Linux box and the extenral LTO device. I switched on a 160MB certified cable of 1 meter and the system is working fine now. The HP Ultrium and the Python are connected on separate SCSI channels, so the transfer speed of the Ultrium is not affected by Python. Regards.
