I'm trying to enable the intel srt ssd caching on my computer but it's failing to see my hdd. I have a 2TB drive that I want to accelerate but the tool only selects my other 1TB and 500GB drives. I've removed the other hdds and now the accelerate tab is completely gone from the menu. This is a clean install of windows 7 and I've got the current RST driver. What's going on?
