I recently bought a 240gb SSD Plus to complement my Samsung 840 Evo. I run Windows 7 64bit on the Samsung and wanted to run all my games and programs off of the Sandisk. The problem is that I have two SATA 6gb/s ports on my motherboard (Asus P8Z77-V LK) and four of the SATA 2 ports. I cannot get the motherboard to see the Sandisk drive when connected to the SATA 3 ports. It will work just fine on the SATA 2 however. I know the SATA 3 ports work because the Samsung will show up fine on both. I have tried different cables (all rated for SATA 3) and updated the BIOS on my motherboard. According to Sandisk SSD Dashboard software my SSD has the latest firmware.
What am I missing to get the SATA 6gb/s to work with this drive?
