I'm getting this same error, under the same attempted pwd removal command with the hdparm bundled with 14.04 Ubuntu. Then also with the latest (9/2015 v 4.98 version from sourceforge.net).
Did the bug come back or was it never really verified to be fixed?
Off-topic:
I'm following my SSD MFG's recommendation for recovery of a SSD that they returned with no-fault found, by performing a security-erase. What's strange, and from what I've read elsewhere, is that the security information printed by hdparm -I /dev/device_node returns that it'll only take "2 minutes" for the erase. Which from what I've read means that its not implemented.
