This is at the top of the list:
Device =SCSI.device
Unit =0
Mount =1
Should the mount not also be 0? It shows file system is AsimCDFS so that part is good.
I have no CD0 in my Devs. AsimCDFS is run from your user-startup. Open the user-startup from S with a text editor and see if you have a line starting ;BEGIN AsimCDFS
There are two folders in Workbench one called AsimCDFS and the other AsimCDFS Buffer
In the main folder you will be able set the prefs
Like...
CD0
asim.atapi.device
Unit#: 001
Autostart DC: 2+partitions
Change Path AsimCDFS:Dis
Autoboot Never
rest empty
Get DOpus on your machine so you can interogate folders, files, icons etc without having to keep opening folders. Icons are not always visible. You can also use the Configure function to see what drives are mounted.
When you mount the CD you should get the diskchanger window for ISO9660 or Juliet.
My guess is that you have a conflict at the moment between two mounting procedures and one is cancelling the other.
Mine works fine with AsimCDFS.
