There are only four sata ports on the "Elite Group" mobo, all in use with
on OS and three recordings drives

It has been in the box, and out of the box
You mentioned having a PCI card with extra SATA ports. Is that

Its a four port PCI card with only the Blueray rom drive connected

I can hear a pop sound when the drive connects or disconnects, and in
desperation I tried something afterwhich I heard only one more pop. More
details to follow when I document more success.
