Thank you for the XPEnology. seems to be working well on my old EX490.
I did some experimenting and here are some findings.
1. I used DS3615x instead and was able to get HD 1 to work.
2. For some odd reason, WD Green drive works but not a Samsung for HD 1.
3. Installing the .pat file on a 2TB WD green drive works but after the auto reboot, the machine would not pick up an ip address.
4. I can only completely do the setup with a 1TB WD green drive.
anyone has ideas as to why the Samsung drive does not work nor why the 2TB WD drive works halfway through only?
