Advice on SCSI CD-RW

Hi, I am in the process of converting my AViiON 3000 into a "media server" (i.e. hook up all my SCSI peripherals to it so I can read and write different media in one place... instead of dragging peripherals from one machine to another). The (old, slow) CD-RW that I had installed in it appears to be dead/dying. At first, I thought it was an issue of not liking "home-recorded" CD's. But, it appears to dislike "real" CD's just as much! :-( Aside from flashing LEDs, it's hard to tell what, if anything, it is doing (fans on the AV3000 are loud). I plan to take the covers off it (the CD-RW) and verify the hub is spinning, actuator arm is moving, etc. Other than that, could be a problem in the optics (which means toss it out...) It's a Yamaha CRW4260t-NB so its no big loss (though it does have a strap to allow it to be configured for different sector sizes). Any other tricks I can try? Any suggestions for a replacement drive? (I'm not looking for anything fancy -- just would be nice to be able to burn CD's on this machine as it has most of my file archive attached to it) Thanks! --don
