Disk Verify Fails
I've been having this problem for quite some time, and decided to figure out exactly what it is. When I burn disks from my eMac's Combo Drive, they never verify correctly. Well, about 2 out of 20 burned did verify but the rest did not.
I have tried just about everything I can think of. Different burn speeds, different CD brands, and a bunch of other stuff.
The CD will finish burning, but when OS X tries to verify the CD, it gives me an error stating that the CD is not reliable, and should be discarded. Yet, when I put the CD back in the drive it reads it fine. I have tried reading all the CDs burned that supposedly did not verify in multiple computers, and never had a problem.
Is my CD burner ruined, or is it just incapable of verifying the CDs? I had it in Panther that I could uncheck the "Verify Disk after Burning" box, but in Tiger it seems this capability is gone. I've had this problem since I got this particular eMac, but never got it checked out.
Here are the specs, if that helps at all:
If you have any suggestions to fix this, that would be nice. Even telling me that I can't burn CDs with it would be fine.
Thanks

Re: Disk Verify Fails
I always see this with toast as well.
If I had to gues.... only guessing... it's because a file that is being burned is also being used or modified, therefore throwing an exception.
this is common with Dantz Retrospect, which screams errors whenever a logfile is updated while backing up.
My guess.... again guessing.... is that the DB and DF files are updating, thus causing the verify failure. It's not a big deal, the discs still read.

Re: Disk Verify Fails
The files weren't being used or modified in any way that I know of while burning the disks.
I think I may have discovered what caused it. They were all file backup disks, so I shoved them as full of files as they could get. My iPhoto library, for example. I tried burning these 700MB disks with only 600MB full, and that seemed to work much better.
