I have an ultrabook hybrid: ssd and hdd. ssd was working on purchase, but after I've re-installed windows -- I can't make it work. I installed the necessary software:

  • IntelRapid
  • ExpressCache
  • EasySettings

but still ssd is not mounted:

(note that the ssd is not mounted).

Here're some system parameters:

Weird. Don't discs mount themselves on their own? Anyway, sounds like it's something simple. It sees the volume and tells you it's not mounted. Couldn't it be something like simply going to the BIOS and setting an option to yes? –  Ariane Jan 12 '13 at 23:21
Status: At risk in the system information list suggests the drive may be defective/failing. It may be not mounting to prevent data from being written to it and then being lost when the drive completely fails. –  K.A Jan 12 '13 at 23:33

I think I had the same issue after I formatted (by mistake) the SSD part of the HD on my laptop. If you have Samsung's EasySupport Center installed on your computer, you should see in the "System status" > "details" whether "Enable ExpressCache" is checked or not. It was not in my case and by checking it in EasySupport, it seemed to have fixed the problem for me. Good luck, elliot
