ASUS P8Q77-M2 supports 6Gb/s SATA ports but fails to detect storage devices.
Hello, I'm in the process of building a NAS using a second hand P8Q77-M2 and i5 3300. I've run into an issue with the two newer 6Gb/s SATA ports are not recognising any drives I connect. The drives all work and are recognised when plugged into the 3Gb/s SATA ports also on the board. There is no M.2 slot to eat up lanes which is the most common answer I've gotten from googling the issue. I've tried looking into the BIOS settings regarding the SATA ports but don't see anything to indicate that the 6Gb/s ports are disabled and I have also updated the BIOS to the latest 1201 version. I've tried with and without a GPU in the 16x PCIe slot which I thought might be eating up the bandwidth. I've already ordered a SATA expansion card to accommodate the additional drives I will be adding but I'd like to know why the 6Gb/s ports are not recognising any drives.
Start with a running operating system and observe the behavior. It's normal for older systems to struggle with additional controllers on modern motherboards, as they're typically PCIe devices meant for OS access but may be overlooked by the BIOS. After that, verify all SATA ports are configured for AHCI in the BIOS settings.
No success yet. I connected via 3Gb/s, used an SSD with Windows 6Gb/s, and booted from an unformatted HDD. In Disk Manager and Device Manager nothing else showed up. BIOS shows AHCI enabled. Edit: Just began installing HexOS; only the SSD appears in the list, same as before.
Thanks to both of you, it seems the board might be the issue. It's not surprising, but still disappointing. I have an expansion card coming soon, which should fix it.
