I have a lite-on 24x that keeps running out of cached memory, hence coasters. This only happens when I try to copy cd's, its fine from the hard drive. I have the cd-rom as the slave on the primary ide channell, and the cd-writer as the master of the secondary ide channell. Is this configuration correct? I'm using nero 5.5. It tells me that the burn proof is activated but it just wont copy some older cd's. Any ideas?
