Look at your data buffer, and it's declaration. When I was working on my test program, I declared it to be a UBYTE array, and then had to cast it to a UWORD array when assigned to scsi_Data. I'm not sure why CBM built the structure showing the data for the data phase as being 16 bit quanities for an 8 bit bus (the SCSI bus). I'm guessing they may require word alignment of the data, but use it in "byte" sized hunks. If the data is mis-aligned, it could cause some interesting effects…which I believe you've seen.
