Does this mean there's something wrong with my drive? Is it bad?

[aguilacuervo]

Hello again,

 

I have a new inconvenience... Nothing bad I hope.

 

I burn this image and everything works fine until verify starts popping I/O errors upon finishing.

 

I try verify with another drive and everything seems fine, no errors pop up.

 

So I'm puzzled... I open the .vob file which has the problem and luckily it's only 2:22 min. long, so I watch it whole first on one drive then on the other.

 

The first drive with the bad verify can't play it through, it stops around 1:54. The second drive plays it fine from start to end.

 

What's this? Is something wrong with my dvd-writer? Is it bad?

 

Here's the log of the first verify:

Thanks!!

Try the other supported write speeds.

 

Is there a reason you're using the 'Incremental' write type rather than the default of 'DAO/SAO' ?

[aguilacuervo]

Hello L.UK,

 

I will try different write speeds on future projects. Thanks.

 

On the other hand, this might be a different issue altogether, but we always come to this, so I'll just ask:

 

Why do you recommend DAO/SAO?

 

The only reason why I use 'Icremental' is that when I read Cynthia's guide, I inferred from her description that it was the safest choice, being it "interruption-proof" and all that. You know stability has never been a big feature with Windows.

 

I used to have many write errors before (reason why I read the guide), and after I moved to 'Incremental' never again have I had a writing process halt on me again. Verify is a different story, but still the errors have been few and small.

 

So, why is it that DAO/SAO is default? I don't get it.

 

Thanks again,

 

and sorry if this goes too off topic.
