As far as I know, laptops only have room for one drive, so yes you would need to remove the hybrid drive that came with the computer, then use restore discs to reinstall the OS and drivers. You may need to contact HP for the restore discs or flash drive.
I bought an HP laptop with 500GB HDD+32GB SSD hybrid drive. Now I want to install a 256GB SSD. How do I do it? DO I need to remove the caching SSD to make it work? Expecting explanations. Thank you.
