OK thanks - if anyone knows of a specific adapter that *will* work I
would like to know - of course having the drive in its internal bay is
likely not to work either since many (most?) bioses will freeze the
drive from the ata command viewpoint such that it can't be unlocked to
pass the secure erase command anyway! So having an external adapter is
probably the only way I can easily do it but I do need to know that
there is an external adapter that will work.  What I was unsure of is
whether there is any that would work since I had been told that usb
can't do it at all!

(I did look at the hdparm man command but did not see the answer to
the latter question)
