I'm trying to get my old laptop to burn a cd. So far all it does is go through all the motions, but at the end the cd is still blank (if it tries and fails, is the cd trash?)
The laptop is an Acer 5315, running Vista with sp2 installed. The drive is a Sony Optiarc CRX880A. I've tried updating the firmware on the drive using a firmware flash utility from the Optiarc website (, and modifying a registry subkey (as per The driver I'm using is cdrom.sys from Microsoft. I forgot what programs I used for the burning, but it's been 4-5 different ones. I haven't tried cleaning the drive with a cardboard copy of a cd yet, but... (grin).
Is there a diagnostic utility out there I can use to do a more in-depth test on the drive? Any other help would be appreciated too!

✔ Best Answer
Try a different brand of blank discs.

"if it tries and fails, is the cd trash?"

It depends on the nature of the write failure. If even a small amount of data has been written to the disc, it can't be used again.

Your burning software should tell you. If you try to burn to a disc which already contains data, It will say something like "the disc is not empty" or "please insert a blank disc"

Moreover, you can usually tell if you look at the data surface of the disc. If it's got dark bands on it, it already contains data and can't be used for burning more data.

I'm not sure if it was a different disk or the fix from Microsoft support that did it (I've since talked to tech support at Optiarc and they told me I had to COLD boot (i.e., power off) after changing the registry; I didn't do that), but it's working now. Thx!
Do have another question, now that the drive is working. I have another .iso file that is 1.5gigs (1,499,463,680; Linux-Mint Cinnamon). How do I get that on a 700mb cd? (I thought a .iso file was a disk image, which leads me to believe it goes on there somehow). Is there some sort of compression I need to use as I'm burning the disk? Is this some sort of 2 disk thing? Do I have to burn it to DVD (can I burn it to DVD and use it as data?).
Yes, I'm way behind on this stuff. Thanks!

If your ISO is 1.5 gigs, then it's an ISO for a DVD, not a CD.
