Hi,  I am having trouble copying a video file off a DVD to a hard drive.

The disk contains (legitimate) 7 files in the usual .VOB format ... viz. including .BUP and .IFO files.  They all copy correctly except the last file (VTS_01_3.VOB) which stops half way through ... eventually I get an error message regarding a failed cyclic redundancy check.

I have tried Windows copy/paste, together with several disk copying programs, but none get passed this block.

Oddly though, the disk plays perfectly all the way through on both computer and the TV's DVD player.

Any suggestions please?

Tks, R.

You could try using Imgburn, I'm fairly certain it has some decent recovery attempt options when coming across bad blocks on a cd/dvd.

Poll, thanks for that .... worth a crack I guess.

I've already tried DVD Decrypter, DVD Fab, DVDSmith, and Nero.

Data on the disk simply can't be read by your computer. The data may be corrupt or more likely the disk has some defect such as a fine scratch or scuff mark. Most players tend to be a bit more forgiving and simply skip ahead past small issues (I am sure there is a technical word for it - I guess its a kind of buffer) you may never even notice, and it doesn't matter for playback. To copy it however requires access to 100% of the data, anything missing or can't be read and it will fail.

There are some data recovery programs around but I have never tried them.

At worst you could use VLC's simple record feature. VLC has many options for format conversion as well.

Handbrake may be the best bet for ease of use in format conversion from DVD or HDD files.

Just tried ImgBurn with no success.

BTW, also tried using three different CD/DVD drives including an external unit (often works for ripping music where one drive fails a couple of tracks).

Do you have a DVD HDD recorder? Perhaps that might let you take a disk image onto the HDD, then you can copy it back onto a new disk.

DVD Shrink 3.2 might work.

DVD Shrink failed at 80% .... same error message.

I think the DVD/HDD recorder unit might just be the answer .... pretty sure I've got one stashed in the attic somewhere .

Thanks all.

PS Doesn't a DVD-to-HDD recorder also copy the file similar to a computer system, and not copy-as-it-plays?

Some do fast copyig this way,  but many allow you to change the bit rate, ( ie LP) and if you end up changing the bit rate I would bet you it is rencoding from a "viewed" file

Is this a DVD-R or a commercial DVD?

Does the DVD play right through anyway?

Behodar: DVD-R

Jaxson: Yes, plays right through using Windows Media Palyer, and my Philip[s DVD player connected to TV.

What size is the file that fails to copy? What is the target filesystem?

Uber: Only 725MB ... it's the last of 3 .VOB files, the others being 99GB each (obviously the file size set by whatever program burned them in the first place).

I've tried NTFS, FAT (hard disk and flashdrive), and a Linux-based external drive as the targets.
