Hi, Dlwharleyman69,
Welcome to Sony Community!
If the drive needs to be replaced or repaired, we highly recommend visiting the nearest Sony Authorized Service Center to better assist you. They have the right tool and knowledge and they will help you better with any hardware-related issue with your unit. Sony does not have a software that tests the SSD cache drive. A replacement drive can also be purchased separately from Encompass: https://sony.encompass.com/model/SONSVT13124CXS. You may contact them here: https://sony.encompass.com/general/Contact-Us.
Best regards,
Vincent
