Jurgen, I think that I may have found what the issue is. The specs from the drive is: - Read/Write 7.50 Watts - Idle 4.00 Watts - Standby 0.97 Watts - Sleep 0.97 Watts
Reading through usr/src/uts/intel/io/dktp/controller/ata/ata_cmd.h and src/uts/intel/io/dktp/controller/ata/ata_disk.c I see that the actual command is ATC_IDLE (line 742). reading through page 135 http://www.seagate.com/support/disc/manuals/ata/d1153r17.pdf I see that Idle also could mean standby ... right? Or not? Regards, Tom.
