<br>
<span style="font-size:10.0pt;font-family:&quot;Courier New&quot;">Thank you John, Curtis and Gerry for your useful notes.</span><br>
<br>
<span style="font-size:10.0pt;font-family:&quot;Courier New&quot;">I was looking after a method which will be as generic as possible - for a &quot;HW-agnostic&quot; 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).</span><br>
<br>
<span style="font-size:10.0pt;font-family:&quot;Courier New&quot;">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.</span><br>
<br>
<span style="font-size:10.0pt;font-family:&quot;Courier New&quot;">I tend to agree with Curtis' bottom line...</span><br>
