i have a SATA HDD so i have 2 open IDE ports on my motherboard. i have 2 dvd writers, a BenQ DW1640 and Pioneer DVR-111D (at DVR-111L TDB MCSE).
i currently have it set so my DVR-111 is my primary master and my DW1640 as my primary slave. i think i did this because i didnt want 2 IDE cables running in my case (for better airflow). i VERY rarely use both drives at the same time. would it make any noticeable difference if i made my DW1640 my secondary master instead of primary slave?
