I suppose there is something wrong with your oktagon.device. Which version of the driver disk do you use? There are four different versions on the Amiga Hardware Database: http://amiga.resource.cx/exp/tandem
What happens if you use the supplied HDInstTools program? Does it find the CF card? Does it allow to create partitions on the CF card? (Warning: this will delete all existing data on it!!)
I haven't an install disk, it wasn't supplied when I bought the used card; I have tried ALL the .dms archives from link above suggested and nothing of these works.
Oktagon.device wasn't present in any of the .dms on amiga.resource. oktapussy.device cannot be used because needs OS > 2.04.
I have tried to download an oktagon.device from an ALF controller on amiga.resource but the "Version" command says 3.20 on my miggy1200, "Error in open" on my Big Box 2000. Really you're right: problem maybe is relative to the oktagon.device, but I haven't install disks (original or copies). Google doesn't help me this time (for the moment!)
Version of HDInstTools program downloaded from amiga.resource, after command "oktamount", starts correctly but says "This program requires a BSC controller" and stop (no partition or HD showed, all "grey").
This is, in absolute, the hardest installation of HW that I have tried!
