Help!! My CDR!!!

[/* jsha */]

Hi.

For some reason, my CDR quit working a while ago. I don't know if it's history,
or if there's a hope.

It's there in dmesg:

ahc0: <Adaptec 2902/04/10/15/20/30C SCSI adapter> port 0xf800-0xf8ff mem 0xfffbf000-0xfffbffff irq 11 at device 15.0 on pci0
aic7850: Single Channel A, SCSI Id=7, 3/253 SCBs
cd0 at ahc0 bus 0 target 3 lun 0
cd0: <YAMAHA CDR400t 1.0m> Removable CD-ROM SCSI-2 device 
cd0: 3.300MB/s transfers
cd0: Attempt to query device size failed: NOT READY, Medium not present - tray closed

It's definately there:

But when I try to burn something:

In cdrdao, things aren't more promising:

0,3,0: YAMAHA CDR400t   Rev: 1.0m
Using driver: Generic SCSI-3/MMC - Version 2.0 (options 0x0000)
WARNING: Unit not ready, still trying...

If anyone has ANY idea as to what might be the problem, please do let me know.
Heck, I'll even burn you a CD with some soothing and rare house/hiphop/funk/soul
music. Or I'll just send you a blank one ;-)
