This may or may not help, but I have used a 1542c with
imagedisk to create
mixed density floppies. Others have then used these to successfully create
new images.
Interesting - I have a 1542 which does not work with ImageDisk or TeleDisk/TESTSD
at single-density - the user reporting the problems also has a 1542 which does not
work with any of the three programs ... Mine is a '1542CF' - I assumed the
'F' ment
"with floppy" ... Is this the same as yours?
I have at least 3 controllers that will work at SD
with imagedisk. I have
tried ID in single density with about 15 different floppy controllers, and
have one more to test. Is there a FAQ about what controllers will write SD
images? If not, I'd gladly maintain a list.
I've found 6-7 that work OK - and I've been adding them to the documentaion.
Feedback on what other controllers do and don't work would be appreciated,
however as noted here - some controllers seem to work for some people and
not others (more likely, there are "minor" version variations in the
controller).
So far - every controller I've tried that passes Chuck's "testsd"
program
also works for me with ImageDisk at single-density - the case I have been
discussing is the only one I am aware of where this has not been the case.

Dave
