I am trying to port the 'smartmontools' package from sourceforge.net to FreeBSD. However, I am running into some issues. I need to be able to send SMART commands (and read responses) to ATA disk drives. At first glance, it looked like the generic ATAPI layer would work great, but I have found that the ATA disk drives do NOT support generic ATAPI commands (through that ATAPICMD ioctl). So now I am at a loss as to how best to proceed. Should I just patch the code in ata-all.c that looks for an ATAPI_MASTER or SLAVE device? (and allow a ATA_MASTER and SLAVE) to receive ATAPI commands? Should I try to work up a new IOCTL to support ATAPI commands to ATA disks? Should I add IOCTL support to the AD device driver? Any suggestions? Ed To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
