Here is the log file from what I did in Parted Magic plus some additional comments from me. I was actually trying to run hdparm secure erase on an SSD, it wasn’t accepting the hdparm commands at all so i tested the commands on my WD Drive in the same SATA bay. Unfortunately the WD drive was loaded with the same drive path as the SSD I had just removed i.e. /dev/sde … This illustrates the danger of using a keyboard where the up arrow is just below the return key and you are working at 4:00 a.m. in the morning. Hope you all have a good laugh.

Comment - I meant to do this - set a security erase password and see what was returned.
=================================================================
root@partedmagic:~# hdparm --user-master u --security-set-pass PASSWORD /dev/sde
security_password=“PASSWORD”
/dev/sde:
Issuing SECURITY_SET_PASS command, password=“PASSWORD”, user=user, mode=high
Comment - I did not mean to do this … Instead of hitting up arrow once more my finger hit the return key.
===========================================================================
root@partedmagic:~# hdparm --user-master u --security-erase PASSWORD /dev/sde
security_password=“PASSWORD”
/dev/sde:
Issuing SECURITY_ERASE command, password=“PASSWORD”, user=user
Then, I had a power cut!
==================
On rebooting the PC into Parted Magic and trying to issue a secure erase command again I see this:
========================================================================
root@partedmagic:~# hdparm --user-master u --security-set-pass PASSWORD /dev/sde --verbose
security_password=“PASSWORD”
/dev/sde:
Issuing SECURITY_SET_PASS command, password=“PASSWORD”, user=user, mode=high
SECURITY_SET_PASS: Input/output error
