Sounds to me like you need to contact the vendor of the interface in
question. If it accepted a security erase command and didn't do it then
it's broken. It's at liberty to refuse it, or report it doesn't know what
you are talking about, but if it just returned and after re-plugging the
device its still using the old keys then it or the device is busted and
it's not something the OS can do much about.
