First, you want to make sure you have Initialized the SSD Drive, you can do this through your operating systems disk management options net look to see if you have the latest UEFI/BIOS for your motherboard. If using a desktop, try another SATA port. If the UEFI/BIOS has the AHCI option, try Enabling/disabling to see if it helps. If none of these work, contact PNY Tech Support who will do their best to assist you.
