It could be your disk(s) conflict with the SCSI id of the SAF-TE device, or there is a termination problem (bus is terminated before SAF-TE device). So try it without disks connected as well. It has always been my impression that the Mylex card hides SAF-TE devices from the host, in order that there be no conflicts over control of the SAF-TE device. Usually if you have a SAF-TE on a Mylex (mly) card, you will get a few "Device gone" messages with the ID of the SAF-TE device(s).
