Thanks to Tom, David and Christopher for their ideas and moral support. Thanks to pure coincidence on Friday the 13th, the great Seagate Tapestor mystery has been solved. The problem turned out to be an IRQ conflict with USB and the SCSI controller on my new machine. We discovered this quite by accident after setting up an exact duplicate of this computer with Windows95 for one of our users. Windows95 yelled about the IRQ 11 conflict between the Adaptec aha1505 and the USB. It instantly clicked with me that the same must be happening on the FreeBSD box. I quickly changed the IRQ of the network card from 10 to 3 and the aha1505 from 11 to 10, rebooted, adjusted the kernel and instant success. Of course not all questions are answered yet which brings me to the next set: What does FreeBSD offer to identify these type of IRQ conflicts? When I first used dump I used a derivative of Curt's suggestion (12/8/96) and used "dump 0ubBf 32 /dev/nrst0 /" which worked but did not include the entire disk (only backed up 14,950 tape blocks vs the 333348 for /usr). I modified it to be the /usr directory and it backed up all of /usr. What do I use to back up the entire disk and how do I determine the optimum parameters for dump, including blocksize (-b 32), for my drive?
