Having had nothing but trouble with my attempts to write stream files using Kryoflux, I truly appreciate all of the time forum members put into trying to help me overcome my problems.
So here is what seems to be the catch - when I read in the floppies (original post), I did not have access to a Windows machine, as I write Mac software, but my Mac Pro 2011 had a fine, working bootcamp partition with XP. So using XP, I read in the floppies from that PPG Waveterm A library. But that seems to be the problem. I borrowed a friends "Real" PC, an Asus motherboard build running Windows 7, and was able to use Kryoflux to read in and write out a DOS floppy with no issue.
So it would seem the broken part of the link was using the Mac Pro booted as a Windows machine. Thus, sadly, my PPG Waveterm A stream files are junk (much as users suspected).
Thanks again to all who posted suggestions that helped me figure out where the problem was.
If anyone is curious to see what a properly streamed Waveterm A disk looks like, the stream files are here: https://www.dropbox.com/transfer/cap_pi ... mucpmo294o
BTW, the last raw-image you posted contains some interesting mfm sectors on the last tracks beside the fact that the rest is all fm code. It looks as if thats the reason why it's not enough to copy the first 77 tracks to get working copies...
Not that long ago I had an issue with a failing capacitor on a video card. The entire machine worked fine, but the floppy drive had constant problems reading. Eventually, I figured out that removing the video card solved the problem, and this video card model had known issues with capacitors failing, and putting noise on the power. I suspect using a KF in that machine with that video card might result in a similar noisy dump.
