There is no problem, it just wasn't done yet. It should be possible to submit respective ATA command via CAM pass interface to spin-down drive immediately or to set wanted power management level, but respective user-level part in camcontrol is also not implemented yet. > Another question is why "camcontrol tur ada0" returns "Unit is not ready" > readcap also doesn't work. It is all SCSI commands. This implementation expects real direct ATA operation without SCSI emulation parts. But this commands should work for ATAPI devices, that are really SCSI deep inside. > My SSD reports write and read cache present, but disabled.

Existing ATA driver enables this features during drive reset sequence. New one doesn't do it yet. -- Alexander MotinReceived on Tue Jul 07 2009 - 17:06:28 UTC
