Updating the firmware from the toolbox is not supported when Windows is running off the drive you are trying to update.
WARNING: This is a Destructive Flash, back up all data on SSD. Proceeding with this update will result in complete loss of data on the SSD. Toolbox will update to drives to firmware version 3.12 first before updating to the latest firmware version. For users with firmware version 3.12, this is not a destructive update.
-Toolbox will not update a primary system drive (e.g. drive letter "C:"). You must run Windows from another drive and then update your SSD using Toolbox.
