Hi, my name's Vincenzo.
I have 2 simple modular storage 100 with old firmware, but in web interface is no possible to update firmware, because I have download the manual but is different.
Next step is change 4 HDD because in web interface are in red color: the repair slot is used, and there is a slot empty in the center. I can put the new HDD in this position or it's necessary to put only in repair slot.
thx e sorry for my english ;-D
