Hi there, you can get the SES drivers from here, just download the file for your OS (32 or 64 bit), right-click the SES device on device manager and select update driver, the search for the SES.
If the drive is still not seen after reloading the drivers, then check if the drive is on disk management (Right-click on computer/my computer> manage> disk management) and see if the drive is there without a letter, or raw, or healthy or unallocated.
