I have new WD Red 2TB Drives that would not be seen by intel raid card and then all of the sudden after several cleanings using diskpart on another machine they somehow appeared.
But after the 1st reboot the raid card failed and I could never get the driver to work so I traded the card in on an HP Smart Array P420 Controller with cache and BBU.
This card has no option to access it at POST as far as I can tell but it does initialize and the storage manager works fine but
once again the card these particular 4 drives are invisible. Any other drive of any size comes right up in the PD list but not these.
What could this be?
