Be aware of course that there is a many-to-many relationship between physical drives and logical drives; a physical drive may have multiple logical drives, and a logical drive may span many physical ones. ISTR IOCTL_SCSI_GET_ADDRESS gives you the data for the first physical if the logical is on multiple physical disks.

Open the drive and use the IOCTL_SCSI_GET_ADDRESS ioctl.

Subject: [ntfsd] Relation between “Logical Drive Letter” and “Scsi
Port/Scsi Bus/Target Id/Logical Unit Id”How to derive a relation between “Logical Drive Letter” and “Scsi
Port/Scsi Bus/Target Id/Logical Unit Id”.E.g.
Assuming Drive “C:” and “D:” has a symbolic link to
“\Device\Harddisk0\Partition1” “\Device\Harddisk1\Partition1” and We
have two scsi cards supporting logical drives like “Scsi Port0/Scsi
Bus0/Target ID0/Logical Unit ID0” and “Scsi Port1/Scsi Bus0/Target
ID0/Logical Unit ID0”.How can one decide that drive “C:” is on “Scsi Port0/Scsi Bus0/Target
ID0/Logical Unit ID0” and drive “D:” is on “Scsi Port1/Scsi Bus0/Target
ID0/Logical Unit ID0”Thanks
