Interesting, I've never had any problems connecting two drives
to an IDE bus as long as the jumpers on the drives are set
correctly. However, my experience with IDE drives has been
short. My main computer was a SCSI Mac until 1998, then I
got a Dell laptop (IDE, but not user-maintained), In 2001
I acquired my still current computer and used dual IDE drives
on one channel as a RAID-1 setup. I never had a problem with
that until one of the drives crashed after 2 years.
In the last year I've built several PCs from parts and almost
always put the hard disk and CD drive on the same IDE channel.
One constant in all of my experience with IDE is that I have
always had the IDE controller and sockets on the main board.
Personally I don't really see much future for hard disks on
an Apple II. It's hard to find a disk less than 40GB at retail
around here and it seems to be the start of closeout time for
40GB at that. SCSI drives are smaller, of course, but also
more expensive. A CF card is just about right and a reasonably
fast "network" drive (i.e. - An image file on my PC hard disk)
is best of all for an Apple II these days, IMO.
