The Intel driver provides two access paths to non-RAID SATA drives:
CSMI SAS STP pass-through (SCSI node) and standard ATA pass-through 
(PhysicalDrive node).
There is no easy way to detect duplicates without knowledge of drive 
identity.

GSmartControl ignores drives with similar identity but smartctl --scan 
does'nt.

You could limit output by "smartctl -d csmi --scan".

Thanks,
Christian
