I think you'll find Bob's disks have dns=3, where as the standard drivers are dns=1 or 0. Just "dmode /xx dns=3" and his disks should read.

If you can provide a link to at least one disk I can examine it and tell you exactly how to get it to mount. There is also a density setting you may need that has to do with if the disk is 48 tpi or 96 tpi.> Gene Heskett gheskett at wdtv.com > Sat Feb 27 19:24:55 EST 2016> > On Saturday 27 February 2016 18:46:10 Ed Orbea wrote:> > >    I'm finally getting around to accessing via my SDC) the Australian> > OS9 POD library files graciously provided by Bob Devries in Feb 2015> > (yeah, I know it's taken me a year).> >    Bob says that they are 720k diskettes and I am having problems> > getting dmode properly set (either in VCC or SDC) to access the> > drives.
