    SubjectRe: Does the linux kernel contain support for ATA Security feature set?
    So when I do a hdparm --security-set-pass NULL /dev/sda

    I get a

    SECURITY_ERASE: Input/output error

    This is with a kernel that doesn't have CONFIG_IDE_TASK_IOCTL=y defined

    I'm also told that for SATA drives that's not necessary anyway. Is
    that correct?

    What should the response be for hdparm if CONFIG_IDE_TASK_IOCTL isn't
    defined for a drive that needs it?

    The drive is an Intel X-25M

    HDDERASE won't work since I'm on a Mac.

    I don't want to create a customized lived CD witth a new kernel unless
    it's necessary.
