}{'lo scotus!
I just have a few basic suggestions and you prob'ly know more about this than I do so humor me ok
.
try setting the jumpers on your hard drives as slave and master accordingly instead of cable select.
I've never seen a secondary master when there was no secondary slave and no primaray slave. I think your second HDD needs to be set to primary slave NOT as secondary master wich the BIOS is seeing right now. Hopefully that will be solved when you set the jumpers to slave and master and not cable select. After you have set the jumpers go back into BIOS and check to see if it still thinks the second HDD is a secondary master. If it does try to change it in BIOS to a primary slave.
I could be wrong, I've only slaved HDD's twice now but its always been just that, a slave HDD not as a secondary master.
