Ok time for me to butt in. I had to remove my Sony CDRW drive as secondary master to install 4.6 this weekend. My secondary slave (as secondary master after the Sony was removed) worked fine. I will send specifics if wanted when I get home and have access to the machine. FWIW I had the same problem on the same machine with 4.5 many months ago. 4.5 and 4.6 complained in the same way "BIG" some thing or other command timeout, resetting, etc., etc. - Michael Hogsett > Thanks Chris. > > The AOpen 52x definitely exhibits the problem. > We have numerous (2000+) of this drive type installed. > Of the 15+ drives tested so far..
