Using a SOHW-1693S with shuttle sn95g5 = problems

I Just got my SOHW-1693S and after installing it I encounterd several problems.
First I played DVD’s to see if it is working properly it took for ever to even load the DVD and go through the DVD’s menu. For some reason when I click on the drive in My Computer it does not give me the error msg which prompts you to input a CD, I am able to access the drive without CD just like a HDD. After that I tried running it on my brothers desktop and everything worked fine. So I of course I tried it in my shuttle and boom, everything crashes when I try using the drive. any suggestions?

Check your IDE cables for nicks, I’ve (nearly) caught mine a couple of times when sliding the drive cage back into my shuttle.
