Radxa Penta SATA HAT Drives not being recognized

To start this device was working fine for a few weeks, using it for a Plex server. The Pi and device lost power one night, and since then the drives aren’t being seen. No blue drive lights for the drives anymore. Just the green power light. Pi is working fine otherwise. The HAT is no longer seeing the drives. Tried reinstalling OS, and reseating everything, no luck. Any suggestions on troubleshooting? Hardware connections all look fine. Thank you!!
