Sorry to dig up an old thread, but I registered, just to say thanks! I was pulling my hair out as only four drives of nine were being detected. Got rid of all the Molex and bam all but two Seagates are being detected. Thank you thank you thank you!!!![Clap]( "Clap")

Are you using any kind of power cable adapters, like four pin molex to SATA power cables, on ANY of the drives in that PC? That's just an example of a somewhat similar problem I had. I used a four pin molex power cable from the PSU, and connected a four pin molex to a dual SATA power connector adapter, for use with SSDs. I used these adapters on several different PCs with different mother boards and SSDs, and they always worked fine. But on one of those PCs I needed to use a SATA power cable from the PSU to a drive, while using the molex power cables and adapters I described, on other drives. The PC would start for a moment, and then shutoff. The only way I could get things working was to use either ALL molex power cables and adapters, or ALL SATA power cables to the drives, I could NOT mix the two. I assume there was some kind of grounding issue when I mixed the two, or other electrical problem caused by the mixed power connections. Your problem is in a general sense the same. When you connected the new drive, for some reason the PSU is detecting some kind of problem, and shuts itself off when you try to start the PC. That is a safety feature, particularly useful with high power PSUs like you have. So you get no power at all to the board and other parts in the PC. The main hint that makes me think this is happening is you can reset things by removing the power cable and then connecting it again. That causes the PSU to reset itself after it went into a protective shutdown state. This is a major clue that indicates it is not the board that is the problem, but something about the power connection to the drive is the cause. The hard part may be determining what exactly is causing this to happen. That's why I asked about the use of any power cable adapters. Your PSU is a single 12V rail design, so balancing power connections is not a requirement. Many things are possible, including the power cable from the PSU being defective, or the drive itself being defective. Does this problem happen when connecting either of the two new HDDs? As Xaltar said, if you just connect the data cable from the drives to the board, with NO power cable, does the problem happen? If you describe the power connections to your drives we might notice something. If you use adapters like I talked about, let us know. |
