Do you see anything in dmesg that might shed more light on it? If you use the -v switch, camcontrol will print out more verbose error information, and should provide text for the error number. What kind of controller are you using? I'm guessing you are using a 12Gb SAS controller given what I see above. What firmware revision is on the controller? The drive is a SATA drive, and SANITIZE is a SCSI command. There are translations defined in the SAT spec to translate SANITIZE to an ATA command. I don't know whether your controller supports those translations or whether the drive supports the underlying ATA BLOCK ERASE EXT command. Ken -- Kenneth Merry ken@FreeBSD.ORG
