I tried Crystal Disk Info and it did not recognize my SSD as it came up as unknown. I'm over my head on this one.
I believe my problem could be System Mechanic. It says it can defrag the SSD but I read where it's never required. System Mechanic does it automatically on reboot when it detects a problem. I think that's the beginning of my lose of data. I will contact the techs at SM and see how to turn off the testing and auto repair.
I also found a update for the firmware on the Vertex drive. It corrects DOS read problems. The BIOS also has to be changed prior to updating. I'll back it up and try it also.
Appreciate your recommendations.
