SanDisk SSD U100 16GB unresponsive/broken

You need to have your storage controller set to RAID mode to enable SSD caching with the Intel Rapid Storage drivers, if your chipset supports it. However, even if it does, it isn’t very straightforward to both check it out and set it that way without potentially rendering your pc inoperable, something I don’t want to take responsibility for.

The ideal scenario would be being able to restore the functionality of the SSD caching system that was previously working with your SanDisk SSD. As for that, I have no idea however.
