I assumed this was using hdparm under MacOS, not Linux?  If this was
under Linux, then that's strange behaviour.

I assume they won't know what to do about it.  Maybe you'll get lucky tho'.

If you haven't tried the hdparm security erase using the SATA controller
under Linux, and don't have any more luck with grml, then you could try
other bootable Linux, such as knoppix (I only suggested grml, because it
comes with hdparm etc. pre-installed, and is my favourite for that sort
of thing - however I've done very little with Macs - mainly Linux on PC
and Linux on ARM).

Personally I wouldn't (I'd keep using it until it fails), but up to you
of course...

Good luck!
