I have a new problem now. I have 6 units of 4TB Seagate HDD and I installed 4 units in the beginning and I added 2 more. Obviously the Syno detected more HDD and asked me to expand. When I clicked Expand, it would start from 0.00% and stopped without even going further to 0.01% Please help. Should I destroy the whole volume and start from the beginning? What if I wanna add more drives in the future? Does the "EXPAND" feature really work?

How do I add drivers/modules ? I'm sorry, I'm new to this XPEnology. Please help.

Anyone knows any RAID Controller/HBA which works with DSM 4.1? I tried LSI00182 - LSI SAS 3081E-R 3Gb/s SAS HBA last night (3x 4TB Seagate connected) but unable to see any DISK under HDD Management I also bought LSI Logic Controller Card LSI00301 SAS 9207-8i 8Port Internal SAS/SATA 6Gb/s PCI Express this morning to try with DSM 4.1. (Obviously it hasn't arrived yet) Please help.
