I also have been stuck on the 48 bit issue for a long time on my 4100 snap, I managed to get a copy of the newest software from adaptec, and I have installed it, and it correctly shows the 4.08 version as i recall, however, I still cannot get past the 137 drive size , I am trying to install some 250's and would like this to be resolved, otherwise I will probably ditch the 4100, as much as I like it, I don't need a 480 gig box since I dont have enough small drives to fill it.
HELP!!!!
Thanks to all, you can send me emails.
