need help: Mac ==> prodos transfer

[laposkymp@bvu.edu]

I have a question.  I have tried and succeeded at transfering files from my
Laser 128EX onto a 3.5" disk with DSK2FILE and then onto a PC.  The files are
complete and intact but I can't seem to get any files back to my computer. 
I get I/O errors tring to view the files using the file viewer in Copy II+.  My
own attempts at find the data have also been unsuccessful.

I was using a Powermac to write the data to the disks.  I know fairly little
about the System 7.5.  I was wondering if the drive on the powermacs is even
capable of writing the data in prodos 8 format.  Or if I need to change the
file types with a resource editor before writing them to my prodos disk or if
there is conversion program out there that I could use to put my files onto a
disk.

I have access to some SE's and some Mac Classic.  Is there any software
available to use those machines to transfer the files and if so where could I
obtain it.

Thanks in advance.
Matt
