You may try a Secure Erase from the Intel® SSD Toolbox or from Linux*.

Thanks Joe for the advice. Here's what I got:
Intel SSD Toolbox 3.23 "Secure Erase": Error - Security Set Password command failed.
Ubuntu hdparm: all hdparm security commands return "Input / Output Error". Drive continues to show as "IntelBootloader" with hdparm -I command.
I even tried HDDERASE in real-mode DOS, but no luck.
Since this SSD identifies itself as "IntelBootloader", is there a way to force a firmware install using hdparm in Ubuntu? I suppose I'll need a proper firmware binary file for this.
In this case you may want to check if your Intel® SSD is still in warranty for replacement.
