Hi, long time reader first time poster. I recently purchased an Areca 1680ix to use in my 2007 Octo Mac Pro. I have been trying for the better part of a week to get an array to initialize. I am using a Sans Digital 8 slot SAS enclosure with 5 1T WD RE3's. I made sure the drives are on the approved list before I purchased them. Every time I try to initialize an array, I get time out errors on various drives. I have tried swapping cables to different locations, only using one channel and four drives, different channels, moving the drives to different locations in the enclosure and I still have drives being reported as failed. This AM I moved the card from my Mac to a PC to try creating and initializing the array from the cards BIOS, and I got the same result. I have tried two different sets of drives also. I also tried to flash the cards BIOS on the PC, it reported that is successfully flashed the BIOS, but it is still reporting ver. 1.47. I am assuming at this point that the 1680ix is faulty, but not being a Raid expert I wanted to get some others opinions before I go through a painful RMA process. Thanks for the help.
