Re: Secondary drive in WD My Book Studio Edition II

The thing is there's no separate device for the second drive. It was
so long before I could see the SMART for it via SAT.

# smartctl --scan
/dev/sda -d scsi # /dev/sda, SCSI device
/dev/sdb -d scsi # /dev/sdb, SCSI device
/dev/sdc -d scsi # /dev/sdc, SCSI device
/dev/sdd -d sat # /dev/sdd [SAT], ATA device
