Hi Philippe
Go to "Control Panel", "Device Manager", open "Disk Drives" and right click on "SanDisk SSD i100 32GB"
Then click on "Properties" in the drop-down box that opens - go to the "Driver" tab and click on the "Disable" bar.
This will resolve the conflict between the internal cache (SanDisk SSD) and the SSD drive you installed, and your system should be faster - at least as fast as it was .
Good luck!
Pierre
