Raq 550 OS on RAQ 4 Hardware Disk Limitation
Once you have installed the RAQ 550 OS on a RAQ 4 you may notice that the largest file you can store on the system is 2 GB. It does not matter how large the hard disk is or how much free space there is on the server.
Also, you are limited to using a hard disk that is less than 127 GB in size since the RAQ 4 hardware only supports LBA24. --ChrisD
