Doing a project writing a hard disk util for OS X. I
need to issue a ioctl(drive, SCSI_IOCTL_SEND_COMMAND
/* 1 */, &tBuf /* parameter block set up for an
INQUIRY to the drive */) and I always get a 0xFF
returned as an error returned for status. I get a
string returned that says: inappropriate ioctl
command. But I'm trying to issue a standard inquiry
so having trouble seeing how this could be so. I've
tried other parameter variations and none work. What
gives?
ioctl must be a popular call that other folks are
making. Does anyone know how to issue an ioctl to a
SCSI or ATA drive and get a valid result for any of
the possible commands. To get to this point I have
validly opened on a Blue G3 the SCSI drive through the
path /dev/disk1.
And yes I will use IOKit to do the same thing when I
write the associated app that goes along with the
commands that this particular company will ship. For
now I need to make a bunch of code that uses ioctls
work like it does under other unices.
Thanks,
