This Intel drive is of a generation that cannot be flashed to a firmware revision that supports Trim aka Discard. I was under the impression the Intel toolkit is only for newer drives.

I did try hdparm 9.27 in the past but that alone was not enough.
Next time I will erase the drive using 9.27 and the correct command.

Or should I worry about the current status and erase again?

Thanks for all your quick replies.
