First thing I would check is the SATA controller mode in BIOS and make 
sure it didn't switch from AHCI to IDE/Legacy/RAID (or whatever you used 
to run it as). This assuming the SSD is connected to the mainboard 
controller of course.

I'm not saying this is what happened but at least we could get that 
possibility out of the way.
