Usually, you will only lose half of your speed capability. It should not 
corrupt the data. On some work computers that use the Juki half-sized 
boards, the speed is halved from 100 MHz/second to a maximum of 50 MHz/ 
second.

Anyway, your transfer rate should be greatly improved with the 80-pin 
cable. The error message was good for something. (Leading to getting a 
better cable)
