You can check in the device manager to see if the ssd is detected correctly as Sandisk SSD and as a normal SATA device. If its not because of the sata controller or you are using RAID configuration it can be that the dashboard will not detect the ssd at all or with missing info.
You can also check if you have the latest version of the dashboard because there were a lot of bug fixes included.
The drive is not detected as a normal ATA device but SCSI drive so the controller prevents the sata commands to pass from the ssd to the os in order to be detected by the dashboard.
you cannot do much at this time but sandisk says that the newer version of the dashboard will resolve this issue.
