I have a SATA to USB adapter that I have to use for my 3rd SSD. If I don't use this adapter, and I try to plug the 3rd SSD directly into the motherboard via regular SATA cable, my only HDD (also connected via SATA cable) will not be recognised at all.

I have tried swapping the molex to SATA adapters that I use for my hard drives.

I have tried using different SATA ports on the mobo.

Could this be a software issue? Maybe something to do with the BIOS?

Thanks for the assistance.
 
First, have you tried shutting down, then plugging SSD and booting up, Does it work? If soo you have to set your sata port to hotswapable.
Sata as default arent plug and play.

Not sure about this one, but this happened to me on my friends PC, not enough resources, I just disabled some LTP ports (for very old printers) and serial port (backward VGA, but its not VGA).

Yes, for every cable/configuration I tried, I booted up/shutdown, but the HDD still wasn't recognised.

I wouldn't know how to disable the LTP ports or serial ports to test that.
 
Since you have motherboard similar to mine, go to Advanced-> Super IO configuration and disable everything since thats for stuff like infrared, serial port parallel port not gonna use.

Try disabling 2 sata ports since you use 4, unless you have DVD drive (if its possible).

Is it recognized into bios?

I disabled the serial port and the parallel port, but not the infrared, as I think I have one device that uses it. I was unable to disable ports as mine a pretty much all taken. Anyway, while I was there, I looked under the boot options and did see the HDD listed.

I then tried booting, and strangely it was the SSD this time that didn't show, not the HDD. So I then went back to the BIOS and into to the....Storage settings (I think) and had a look at the settings for the SSD. Turns out the SSD was set as a HDD for some reason. So I put it on SSD mode, and viola, both my hard drives are working now!

So I'm not sure if it was what you told me to do that fixed it, or my little discovery, but either way, thank you!
