I know I'll be interested. I decided to reinstall version 188.8.131.52 on my system with XP SP3. I have been following a particular procedure that works better for me with external USB hard drives in that I always shut down before removing a drive and always reconnect the drive before starting up. That helps with any other issues of drive recognition. So far, after reinstalling version 5, it is working without any issues. I will know more when I have gone through the process of shutting down and then restarting, but I think it will work fine. Added: Today, I had to resort to a last known good configuration to get out of a boot loop after starting from cold with the USB hard drive attached. It worked okay after that and after another cold start. It's definitely related to recognition of the drive and a driver loading at the same time, probably the ESET driver. Since 4.xxx doesn't exhibit this issue, it's the difference in the way 184.108.40.206 works, but beyond that I do not know. I'll keep watching it and decide whether to go back to 220.127.116.11 again at some point.
