Problem with Toast 7 or internal drive?

[rodneyg]

I have been trying to troubleshoot this problem for weeks now, but maybe someone can help me further.

 

Problem: When writing data DVDs in Toast 7, I get three kinds of failures on 50% of my DVD's - Failure during writing that causes an error, failure on verification that causes an error, or failure when writing the data from the a completed DVD back to the computer (missing files error).

 

Equipment: G5 with Superdrive, OS 10.4.7 with two internal hard drives.

 

Workflow: Write digital wedding images to DVD using Toast from the G5 secondary internal hard drive. Then Write images from DVD back to the same hard drive for further processing.

 

Things I have already tried:

 

I have tried both Sony and Maxell DVD-R discs. I have tried writing at 8x speed and instead of best. I have tried using both the internal superdrive and an external firewire drive.

 

My secondary internal drive is divided into two partitions. A scratch partition, and a partition that holds a years worth of wedding images. In the third type of failure above where the failure happens during copying of the DVD back to the hard drive I find that it only happens when writing back to the same drive partition. If I instead copy from the dVD back to the "scratch" partition of the same drive or another totally different drive the failure does not happen.

 

This leads me to believe that maybe the error is on the G5's internal secondary drive that i write to and from. I have run disk warrior and disk utility, but if finds nothing wrong with the secondary drive.

 

Anyone know what else could be causing the problem? Should I replace the internal secondary hard drive or would reformmating it resolve the problem?

I would first suggest different media.  I know you tried Sony and Maxell, but some drives are just picky about media, especially Apples drives.  Taiyo Yuden is the best, but Verbatim has also always worked well for me.

 

With any DVD media you try, always get info on the disc in Toast and check the Media ID website to see how well it is reviewed.  If it gets low reviews, it's usually not good media.

Where do I find the Media ID website?

I found it using the "more" button in Toast next to the disc ID.

 

It looks like the discs I have been using have a poor rating. This could be the cause, but I am going to reformat the drive just in case.
