My motherboard luckily has two IDE channels. I've got 3 IDE devices. One is a backup Hitachi HDD, where all of my ISO's are stored. The other two are ODD's, an LG GSA-H42L and a Lite-On LH-20A1H. Currently, I've got the Hitachi on the primary master channel running in UDMA 6 mode. The LG is on the secondary master running in UDMA 4 while the Lite-On is on the secondary slave running in UDMA 2.
Right now, I cannot use both ODD's at the same time. If I try, both drives lock up and cease functioning. I'd like to be able to at least write a LightScribe label to one disc while ripping/burning another. I seem to get better burns and scans from my Lite-On, so I'm thinking of switching this to the secondary master channel. I'm also leaning toward throwing the LG onto the primary slave channel, because I'm essentially turning it into a LightScribe-only drive. This makes sense to me as the data for this functionality is stored on my OS/SATA HDD.
So, after all is said and done, ISO's will be written/retrieved to/from the primary master and scanned/burned to/from the secondary master. My only concern is whether sending the LightScribe commands to the primary slave while ISO's are either being written or retrieved will affect my burns/scans. How would you guys configure this mess?
