Hi I got a little bit further with my problems. I use a WD utility to write zeros to the both my 80Gb disks and the I created the array with the promise controller and installed with noprobe When it got to diskdruid is asks if ist should initialize sda, hde and hdg. I answered only yes to sda, and the installed worked fine and fast too. After reboot the bootsequence stopped at the promise controller, and I had to reboot and then rerbuild the mirror. After rebuilding I could boot until right after the partitions were checked, then it seems lilke it looses connection to one of the drives, as I had to reboot and rebuild the mirror again. The problem is always the disk on channel1. No matter if I swap disks. I then turned the mirror in to two 1-disk-stripes and now it boots fine on sda. Can I turn sda and sdb into a linux softarray at this point. I have only tried to do it during install. In both situations i get an dependency error on boot that some symbols in FastTrak.o failed. Do I have a defective 20265 or what's haunting me?.. I have changed the cables and tried some other discs. - Jens W.
