Hi, all, On my system using the "old" ATA driver, I can use a command like this to get useful information about my disk drives:
------------------------------------------------------------ nas-pmh# atacontrol cap ad4 Protocol SATA revision 2.x device model ST32000542AS serial number 5XW251QF firmware revision CC34 cylinders 16383 heads 16 sectors/track 63 lba supported 268435455 sectors lba48 supported 3907029168 sectors dma supported overlap not supported Feature Support Enable Value Vendor write cache yes yes read ahead yes yes Native Command Queuing (NCQ) yes - 31/0x1F Tagged Command Queuing (TCQ) no no 31/0x1F SMART yes yes microcode download yes yes security yes no power management yes yes advanced power management yes yes 49344/0xC0C0 automatic acoustic management yes yes 254/0xFE 254/0xFE ------------------------------------------------------------ When I switch to the new AHCI driver the drives are connected to the CAM subsystem: ------------------------------------------------------------ nas-pmh# camcontrol devlist <ST32000542AS CC34> at scbus0 target 0 lun 0 (ada0,pass0) <ST32000542AS CC34> at scbus1 target 0 lun 0 (ada1,pass1) <ST32000542AS CC34> at scbus2 target 0 lun 0 (ada2,pass2) <ST32000542AS CC34> at scbus3 target 0 lun 0 (ada3,pass3) <JetFlash Transcend 2GB 8.07> at scbus4 target 0 lun 0 (da0,pass4) ------------------------------------------------------------ But: ------------------------------------------------------------ nas-pmh# camcontrol inquiry ada0 nas-pmh# camcontrol readcap ada0 (pass0:ahcich0:0:0:0): READ CAPACITY(10). CDB: 25 0 0 0 0 0 0 0 0 0 (pass0:ahcich0:0:0:0): CAM status: CCB request was invalid ------------------------------------------------------------ Obvious question: is there a way to get the same information (NCQ support, write cache status, ...) with the new driver?
