This is most likely where the media is truly ATA and not ATAPI.
Thus there is an issue WRT Linux.
I have tricks up the sleeve that are no added yet.....sheesh I have at
least another 100K in code in various brain dumps to create.

Understandable.....the way companies run loose WRT to standard committees
that have failed to define things in the first place correctly......
We will not go there today, I jest spent three days voting and arguing
standards.....

The old ATA/ATAPI analyzer always exposes issues.
I hope to have one as a GIFT from Seagate, and not have to sell to much to
them in exchange.

I called them on Friday and Mr. Miller was out until 2pm. I left my
direct cell number and asked for OBS to call. Still waiting.
They are driving distance for me to visit for a day to get it fixed
correctly inhouse, but do not reply.
Until OBS responds, I have other issues to fix.
Understand that all the have to do is respond and be willing to work with
and not ignore. I do not want their poeple resources only a few questions
and sample code if absolutely needed.
