I just got my new intel ssd today. I unplugged my old hdd and plugged in my ssd. My motherboard has 2x6gb/s sata ports and 4 3gbs sata ports. I plugged in my ssd into the 6gbs sata port and turned on my computer and went into bios only to find out that my ssd wasn't being detected.
I took it out of the 6gbs port and put it in the 3gbs port and it worked. So, I proceeded to install a fresh copy of win 7. After I installed windows 7 and all of the drivers I plugged my hdd back in. I plugged it into the 3gbs port. For some odd reason it won't recognize the hdd. So I went ahead and unplugged the ssd and left the hdd in and booted it up. This time bios detected it.
There is probably a simple way to fix this but I don't know how to properly ask the question in google so I am here asking the community.
