There can be problems resulting from differences between the head (or track)alignments between machines.

Brand new factory formatted floppies sometimes get unusable files the first time they are used. I recently wrote 10 brand-new floppies on one machine (one file each). 8 files were usable when I tried to read them on another machine.

Formatting on the machines to be used is the right idea, but doing the formatting on the laptop might be a mistake. If its floppies can be read on other machines, that says its alignment is "better". So formatting on the other machine which has problems reading might be better.

To save wasting too much time, and because the files are important:

1) Get "enough" floppies formatted (full formatting) on each machine. That way, you'll have two chances on each file, with the different track alignments. If any errors are detected on a floppy during the format, don't use it.

2) Most importantly, use the file-compare DOS utility after the writes. (I vaguely suspect that xcopy might have a verify option to do it automatically.)

Thanks for all the help :)
