Hello
My port multiplier capable eSATA Express Card refuses to talk to my
external HDD box (2 HDDs, JBOD mode).
Inserting the card into the Express Card slot looks normal:

Sometimes the messages look a bit different and one of the HDDs is
detected but never both.
The initial error seems to always be "failed to read SCR 0".
Does this look like a hardware or a software problem?
