I probably turned 30 disks into coasters while investigating this problem, trying every troubleshooting trick I know to find the source of the problem. Converting the source files to WAV format and caching them locally didn’t help. The problem wasn’t software, either, as I found by repeating the issue with multiple burning programs, including Media Monkey and Easy Media Creator 10.
In several forum posts, I had read recommendations for special disks designed to clean the laser on a CD/DVD player/burner [..] When I received the product and removed it from its packaging, I have to confess I was skeptical. It looks like a regular music CD with instructions on the label side and a half dozen small brushes arranged in a track on the bottom (shiny side) near the center of the disk. In Windows Media Player, it plays like a music CD, with 14 tracks that include audio instructions delivered in a friendly female voice, along with some test tones to help you determine whether your speakers are wired correctly.
After completing the entire suite of tests in 10 minutes or so, I popped in a blank CD, fired up Media Monkey, and told the software to burn a collection of FLAC files from a network location to CD, converting them to WAV files in a local cache on the fly. Surprise! The first disk burned just fine. As did a second, a third, and a fourth.
I just finished spec'ing out a computer build that nearly required a slim optical drive. Frankly, I'm not a fan of slot loaders at all, so there's not one I can particularly recommend.
But mounting a slim drive in a full-height 5.25" bay should be doable. Not pretty, but doable. I don't know of a mounting bracket offhand, which is what you'd really want, but I expect you'll be able to juryrig something if you can't find an existing product.
You'll need a slim SATA 7P-to-std adapter cable (like this one -- this is an example, not a product recommendation) to hook up the final product. The optical drive itself won't come with one (unless you're buying a retail version instead of an OEM drive).
