Sorry, for some reason I didn't get the first email in this thread.
(https://debbugs.gnu.org/cgi/bugreport.cgi?bug=51407)

The logs you included are from the kernel, not from parted, and parted
doesn't deal with sense data or changing the drive capacity, that's all
in the kernel driver for the drive.

If parted it having problems handling this, that might be something we
can improve. It's possible that whatever errors are returned by the
kernel aren't being checked, but I don't have any way to tell without
either a parted traceback, or doing this myself. I don't think I have
any drives capable of secure erase, so someone with access to one will
need to dig into this more deeply. eg. running parted via strace to
capture any unexpected error codes from the kernel.
