I am having the same problem with my 330 series 120 GB SSD. Just installed it and mine also appears on the Bios and the Device Manager but not under the list of drives under My Computer. I am also running Windows 8.
The Intel SSD Toolbox says
"The Intel SSD Toolbox cannot communicate with the selected Intel SSD.
Consider changing to another storage driver compatible with your system and try the tool again."
Any idea what driver and where to find?
Sorry, not trying to hijack your thread, but it sounds like we have the identical problem.
