Verification Fails When Using Toast

[Mayo]

The last 2-3 data CDs I have burned on my iBook produced the following error message: Mismatch at byte 7/sector 3134. Verification failed.

The folders/files appear to be accessible on the CD.  I have checked the discussion boards at Roxio and other online sources with success, so I am hoping that someone here will experience with this or can point me somewhere else to look.

I am running Toast 5.1.4 on OS 9.2.2.  It is a Toshiba DVD-ROM SD-R2002 with driver 1.4.7. I haven't been able to locate a firmware number...  Where is it hiding?  The media are TDK Data CD-R, which have worked fine in the past.  Granted, I have burned only a handful of CDs on the iBook.

Mayo, The firmware may be found by opening Toast, and then selecting Recorder/Recorder info from the menu bar.

Now, if only the Verification problem were so easily resolved...

Thanks for the info Harv; I had been looking in the Apple System Profiler.  Doesn't that seem like a logical place for the firmware information?

The firmware appears to be current, so I update Toast from 5.1.4 to 5.2.  I haven't tested it yet, but DiscBurner seems to work just fine, so I am assuming that this is a Toast-related glitch.

My primary concern is that something is worng with the CD-R burner, seeing as how my one-year warranty just expired and I just could not make myself purchase AppleCare...  But all seems well, since the burned data is accessible, so What, me Worry???

Not much of a help    , but I don't even run that verification thing (and I'm still using Toast 4.1.3 OEM/OS 9). The question becomes, can these CD's be read by any reader? That is enough of a 'verification' for most data and is just as quick. Not saying I wouldn't (like you) want to find a better fix, but it may just be a software/burner only problem.

"...data is accessable, so What, me Worry?" Don't read Mad much anymore!

I suppose the Mad reference dates me a bit...  I haven't read it in almost forty years. I once had this big box of old comics, Mads, etc. but the family cat decided to use the box as a latrine and they just were not the same after that...  

   

However, my collection of original 60s and 70s underground comics are safely tucked away into plastic sleeves and are in a box on a very high shelf.  Most are in excellent condition, except for a large-format Harold Head that is well-read, to say the least.

Those old Zap Comics should be worth  something one of thse days...

Mayo, Now that ABD has mentioned it, I too used to have verification problems with Toast 5.x on OS 9.x on a 7600 with an external LaCie (Matsushita) drive. And I never did get the issue truly resolved.

In my case, the error code would change with each burn, but never did I encounter a condition where the CD could not be read or that it burned unsatisfactory.

As I recall, you can bypass the verification process by holding down the Return key just before the verification process begins.

But if you are still frustrated by all this, the condition may be avoided by going to OS X and installing Toast Titanium. Or, perhaps a new 17" PB with Super Drive is what you need.

I have my eye on a 12" PB, but MacWorld says in its current issue that the little bugger is quite hot under the harddrive.  I think they measured it at 102 degrees...

I think that I will wait and see if Rev. B cools things off a bit!

-----
Update Toast 5.0 Titanium or later to 5.2 (compatible with Mac OS 9.1 and higher, including Mac OS 10.2)

I'm behind the times!

Thought 5.2. was for X only.

Suppose I'd better turn my bell-bottom pants into shorts.

Toast can be annoyingly picky about verification and initial burning attempts.

Many times I have begun a burn and several seconds into the start I get a message that there is some sort of problem at whatever byte or sector and the burn process has failed. Theoretically this destroys the disk for anything further and indeed if I go back and attempt the burn again Toast asks for a viable disk.
However, if I remove the disk, insert a new one, do the burn, then use the "destroyed" disk for the next burn, it works just fine and verifies it, too.

Go figure.
