If your drive dies and is no longer recognised by the computer or even external drive bay try this : 1) Plug the drive into your laptop or PC and boot straight to the BIOS 2) Wait 20 mins 3) Turn off PC/ laptop 4) Unplug drive for 30 secs Repeat the above 2-3 times. This will take the drive through a power cycle and force the SSD firmware to reset. Personal Experience Just had this happen with a drive after killing the power of the laptop without shutting down. Crucial said to do the above and... voila drive up and running again. Has anyone heard of non crucial drives needing to be reset in this manner?
