<font size=2 face="Courier New">(Adding John's final note to keep it single-threaded)</font><br><br><font size=2 face="Courier New">Thank you John, Curtis and Gerry for
your useful notes.</font><br><br><font size=2 face="Courier New">I was looking after a method which
will be as generic as possible - for a "HW-agnostic" environment
- where the type of drive and FW is not known in advance (some enterprise
drive spec do have a SED bit - but I cannot trust that).</font><br><br><font size=2 face="Courier New">Combining all the comments I realise
now that if the system SW is designed to do TCG SED, then the right way
would be to send a level 0 discovery to all the devices and rule out those
who do not allow to proceed with the process.</font><br><br><font size=2 face="Courier New">I tend to agree with Curtis' bottom
line...</font><br><br><font size=2 face="Courier New">Many thanks,</font><br><font size=2 face="Courier New">Amir</font><br><br><font size=2 face="Courier New">--</font><br><br><font size=2 color=#004080 face="Calibri">Amir, </font><br><font size=2 color=#004080 face="Calibri"> </font><br><font size=2 color=#004080 face="Calibri">While there has been a fair
