Not a lot of messages here to tell by.  I only have 1 SATA disk
installed on my system, but I see:

(yes, I have a small real SCSI drive on my system, so my SATA drive is sdb.)

You need to look further into your /var/log/dmesg file to find all of
the messages associated with your drive.  If you don't see it there,
perhaps you have a cabling issue?

Stuff in /dev is created either during boot, or by hotplug events.  If
the system doesn't see the drive, there won't be a device node for it in
/dev .
