After spending the last couple days trying everything I can think of, I'm finally throwing in the towel and asking for help.:hammer: I finally got the time and the last couple parts I needed to get my A4000T set up. Everything seemed to be going well until I tried to get my SCSI drive to work. I'm using a CS-MKIII as my controller and I disabled the A4000T's scsi using the NoNCRscsi module loaded into my deneb's flash rom (although I have tried this without it, too). I have active terminators at both ends of the scsi cable with the CS and hdd in the middle. The hdd is currently jumpered for ID 2 and has term power disabled. Here's the problem, I can see the hdd in hdtoolbox using cybppc.device. I can create partitions using hdtoolbox but they refuse to be mounted, as far as I can tell. Normally, I'd set up the partition sizes, file system, then save and reboot when prompted after exiting hdtoolbox, and finally format the partitions after rebooting when the names I gave the partions would usually appear on the workbench. Except now the partitions don't appear on the workbench after the reboot. They appear to be there in hdtoolbox but I can't seem to get them to mount in workbench. I'm running a fairly clean install of ClassicWB 3.9 and I've tried both FFS and SFS with the same result. They also don't show up in the early boot menu. The only hardware change that I've made coming from my A4000D is that I updated my CS to the latest official firmware. My system is currently being booted from my CF to ide adapter and everything is pretty much stock except for the deneb, picasso IV, and CSMKIII. Anybody with any ideas on what I'm doing wrong would be appreciated.
