Accessing VOB failure & I/O error

[jerrygref]

I've been trying to copy some DVDs (my own productions) and I'm suddenly getting a load of error messages.

 

The message reads "...file VTS-01.-1.VOB could not be accessed (Data fork, -36)." When I click the OK button, I get a second message informing me of the I/O error, telling me that the original might be copy-protected (which it isn't).

 

I did change the media back to a brand that I've had no trouble with in the past, at least in terms of the target DVD. (I was copying from an external Lacie drive into my Mac's drive.)

 

I have been using some new media of late (SONY) as opposed to TDK (which I normally use). Would it matter if the source DVD in the Lacie machine was a bad media, and not the target media in the Mac?

 

Also, I've noticed that my Lacie drive won't recognize/record with the newer 1x-16x discs, but doesn't have a problem playing them. Would that be part of the problem?

 

thanks...

As an experiment, try dragging the VIDEO_TS folder from the DVD to the hard drive in the Finder. Also, try using Disc Utility to create a disk image from the DVD. Do these work okay.

 

I'm presuming you are using the Toast Copy window to make duplicate copies of your DVD. If not, please help me understand the process you're using.

 

One more thing. Try shutting down the Mac and leaving it off for about 10 minutes before restarting.

I have already tried dragging the VIDEO_TS folder from the DVD to the Toast window, but I will try dragging it to the hard drive.

 

Yes, I was using the Toast Copy window, as I do most of the time. As an alternate attempt, I tried the VIDEO_TS folder drag.

 

I'll give the shutdown a try, too.

Okay, I couldn't even copy the folder to the hard drive, as I got a very similar message saying that "some data could not be read or copied" and again mentioned the -36 error.

 

Any guesses?

I'm vaguely recalling someone else having a similar issue and I believe it turned out to be media incompatibility with the drive. It could have been Sony media that was the issue as well. I wish I could remember where I saw this. You might try searching through this forum and the Toast 6 forum.

 

Have you updated the firmware on the LaCie drive in the past few months? I think their latest firmware update was released in January.

 

Try inserting the DVD and selecting it in the Toast Media Browser. Go down to the title level in the browser (using the lower button). There you may be able to extract individual titles to the Toast Video window. Toast will write the MPEG files to the Roxio Converted Items folder. You'd lose your existing menus this way but it may be a way to get the video off the disc.

 

The only other thing I can think of is since this is a Firewire drive you might try downloading and applying Apple's combined system update on top of your existing OS install. This is known to fix bizarre little Firewire and USB issues that pop up after incremental system updates.

Well, I've tried two different things on this attempt, which has resulted in success. It was only at this latest attempt that I actually got around to shutting down for 10 minutes.

 

Also, I did indeed fail to update the latest drivers for the Lacie drive (which also called for a shutdown).

 

After these moves, I did succeed to first make a successful copy by dragging the VIDEO folder to the drive, then using Toast to make a disc from the VIDEO_TS folder.

 

Then, just as a test, I went back to the traditional route by just copying the master disk from the external drive and was successful that way, too. (Both copies were made with the SONY media, as well.)

 

Thanks for your assistance on this problem.
