The link is moved from SEL1 to SEL0 with a soldering iron. That's it! Your drive has now had its drive select ID altered to work with your ST!
PROBLEM DRIVES
After testing 4 drives out dated JUN2002 on my ST, these all failed to work. I tried one on my stock falcon and while it worked, it was unreliable. A later drive worked perfectly. So the SONY chips are questionable. It is difficult to say if the "E" version is to blame, or it was the year of manufacture to blame. I will try and keep a list of the drives I come across..
I am marking drives as BAD if they have a SONY chip. I never tested if the drives worked correctly as a PC drive or not as I have only been using them on a Atari ST/Falcon. In anycase, I would avoid drives with SONY chips, or drives dated before 2004.
