When you use a SMART IOCTL
call to an IDE hard disk that is configured as a slave to a non-smart ATAPI master device, the call may not work correctly. If you are using third-party software to monitor the health of the computer's smart hard disk and it is configured as a slave to a non-smart ATAPI device, the software may not be aware of the drive at all.
This problem can occur when an ATAPI device (such as a CD-ROM drive) that does not support SMART IOCTL
calls is configured as a master IDE device. This is because the SMART IOCTL
call references a master device TargetID in a SCSI Request Block, which is always returned as zero (0).
