My Toshiba laptop keeps ejecting the cds I stick in the cd rom....it reads them and then then ejets them in less then a minute

The optical drive has separate hardware for reading CD-disks and for reading DVD-disks.
So, "half" of the drive has failed. Replace the drive, since that will be less-expensive than an attempt at a repair.

Sorry, but this device does not burn DVDs. It just reads them.

in device manager try uninstalling and reinstalling the cd-rom driver. If that don't work the infered reader is probably bad

1) The CD you're trying may be defective or empty. Try a different CD, one that you know for sure is good, maybe a music CD.
2) The lens may be dirty. Open the cd door and blast some compressed air into it

I think belt of your cd rom may be corrupted or the lens are damaged. Please either one may be happened.

Yes, that's what it looks like. Make sure you put this in the right section next time, though.

there is nothing to be worried about. it sometimes happen tht many dvds run very smoothly and some not. its common

I had similar problem on a Toshiba Satellite A30 laptop, I simply had to reconnect DVD drive. It usually loosing it's connection with motherboard and drive is visible in My Computer but it doesn't recognize any discs. If reconnection does not solve your issue you may try to update your DVD firmware and if it won't help replace DVD drive. Good Luck!

yes..it's most likely kaput. I have a tecra, and I'm on my second CD/DVD replacement. They are easy to find and replace(one screw underneath, and just slide em out)..

please stop smoking near your harware
