Can not copy .DAT files from CD to my hard

In The Name Of God

I'll be so Thankfull if you guide me ;
I face this error when i want copy dat files from video cds to my hard (both ext3 & fuseblk types).But it does not have any problem with other formats e.g mp3 .
i have tested tar and dd but no result .
i have tested this guide but also no result yet .
and i'm sure cds are OK and they are not corrupted.
any opinion ?

regards dehqan

I'm not entirely sure what you're trying to do.

CD audio is stored as 2 channels, 16 bit, and 44.1kHz audio in BIG endian format. Typical WAV files are basically the same and LITTLE endian. Audio on DVD is typically 48kHz.

So to play them as you may not be able to in xmms and other players because it doesn't recognize the headers, or there are no headers, you can use aplay from the alsa packages.

aplay -c 2 -r 44100 -t wav -f S16_BE CD_TRACK.DAT
(or .cdr if you use sox to create them)

cdda2wav if you want to extract the audio from a CD. And various other methods. Not that I know what you're trying to do. Not that more modern drives have DRM type stuff in them, which actively prevents you from doing things like a straight copy. I'm not sure if that's your issue, you've provided too little in the details department to make that determination.

Is this a DVD-A disc? Or something else odd? DVD-A is 24 bit 96kHz audio. Not that I know the exact details yet as I don't have any of those types of media.
