BleepingComputer.com: CD in burner not recognized

I have a recurring problem with my CD/DVD burner. After burning a few CDs I find that my Lenovo 3000 desktop (Vista Business) does not accept the fact that there is a blank CD in the burner. not only that, but pressing Eject has no effect. The Lenovo doesn't have the usual tiny hole beside the tray so the only way to overcome the problem is to turn of the computer and do a cold boot. Sometimes I have to do this a couple of times. I have run various registry repairers and defragmenters without success.

Does anybody have any suggestions as to how I can fix this problem permanently? My drivers are up to date.

One of these may help:
1. Uninstall the drive through Device Manager.
Restart computer. The drive will be automatically reinstalled.
or...
2. http://support.microsoft.com/kb/314060
Restart computer.
or...
3. Download, and run Restore Missing CD Drive patch
Double click on cdgone.zip to unzip it.
Right click on cdgone.reg, click Merge.
Accept registry merge.
Restart computer.
or...
4. Go to Device Manager, click a "+" sign next to IDE ATA/ATAPI Controllers.
You'll see two items:
- ATA Channel0 (or Primary Channel)
- ATA Channel1 (or Secondary Channel)
Right click on each of them, and click Uninstall. Confirm.
Restart Windows. They'll be automatically reinstalled.

Thanks Broni, I will try your suggestions one at a time, surely one will work! The problem doesn't always occur so I'll have to wait and see in each case.

No problem.
Even, if it's not happening right now, you can safely perform those 4 steps anytime.
It won't hurt anything.
