Hi Everyone.

I have a 2 days old XPS 14 (L421X) with 500GB hard drive + 32GB SSD.

I find out about SSD caching, and I'm trying to activate Intel Smart Response within the pre-installed Intel Rapid Storage app. 

But no matter which setting I use (Full capacity, or 18.6GB, Enhanced or maximized mode...) it won't activate.

I always have an error: "An unknown error occurred while an operation was in progress. The operation could not be completed"

I have a Data partition on the SSD (which is around 20GB) that Dell created... but I don't think it can be a problem as the software should erase everything.

It seems that something is accessing the SSD drive and don't allowed the app to do its job.

Does anyone have the same problem or know a workaround ? I've searched a lot on the web and the forum and couldn't get close to an answer.

Thanks in advance for your help

Regards.
