Great site, from one of the post here, it inspired me to do something similar and make a build.
Before I put all the items in case, I wanted to test all components and make sure things work and
thats when I ran into one issue that I need help with. The Seagate 8TB SAS drive is not being recognized by LSI controller car, but it does recognize the Hitachi 3TB SAS drive. Could the Seagate drives be bad?

CPU - 2x E5-2689 Motherboard - SUPERMICRO X9DRD-LF PSU - EVGA 500W 80PLUS Certified ATX PSU Cable - Athena Power CABLE-YEPS828 6 in.

I have done a bit of research on the subject but I am not an expert on SAS, so if someone with more knowledge would like to correct me, please do so.
My guess is that the problem is because the 8TB Seagate drives use 4K sectors and the SAS Controller you are using does not support 4K sectors. If I am correct, I don’t believe that there is anything that you can do about it, other than to get a new SAS Controller that supports 4K sectors.
You can look at the following post to see which SAS Controllers support 4K sectors.
Sorry I don’t have better news for you, but I do hope that it helps.
The most likely problem with an unrecognized drive on an HBA that recognizes other drives is that the power cable to the ‘bad’ drive has 3.3v on pin5. It’s easy to test and fix: SATA Drive 3.3v Power Cable Mod Tutorial
