Here's my second computer problem:

I'm using a Plextor DVD-R/RW PX-712SA (serial ATA) optical drive, running on an ASUS K8N-E Deluxe mobo. Occasionally when I swap DVDs or CDs, the drive won't immediately recognize the new DVD/CD. Opening and closing the drive usually solves this problem, but it's really annoying and I want to fix it.

I'm also running a Serial ATA HDD, if that helps.
