5.25 Drive Timing Issues?

[Sam Latella <powergs@macgui.com>]

I've got several types of the 5.25 drives for the Apple II.

DuoDisk 5.25 drive
Old style Disk II 5.25 Drive
New style 5.25 drive

The issue is the 5.25 floppies I've created disk on the Duodisk and it works
as well as the old style Disk II drive.
However, when I use it in the newer style Disk II drive it does not boot up.
The new style disk II will boot up original disks but not copied ones.

I think somewhere each drive is timing a bit different when copy data..  How
do I calibrate each drive back to the same settings?

Thanks,
Sam
