Testing you have done shows that the RAID unit works fine. There is a setting that must be set within the ADTX RAID called “Extended Bit”. This needs to be set to ON. Directions on how to do this are contained in the Users Manual that came with the unit. I would also recommend that you download and install the AVC-L software that allows you to configure the LU Masking and return these settings to default to complete testing. Please feel free to call ADTX Technical Support @ 949-583-2993 ext: 114 or 112.
