File System : mkfs failed!!! Error = 5
File System : Preposterous size -1963429888

Ok, folks....still cannot get 4 400's to go raid 5. These are the errors I recieve in the log file. I have even put all 4 drives on an external power supply, and run just the MOBO and fans on the original PS. Maybe the TB limit is a problem for the 4000?
I was able to get a raid 5 array with 3 400's, so that is pretty good...
