I think the problem is that your CD-ROM drive is timing out before the write to the hard drive finishes. I have 2 suggestions for you. 1) You can download the VCDgear program (do a search on the internet for it) and it should be able to copy the file to your hard drive without timing out. Use it to convert the file from DAT->MPEG. 2) If you understand Unix, you can install the Cygwin toolkit ( and use the tar command to copy the file to your hard drive. Something like this should work: tar cvf d:\MPEGAV\AVSEQ02.DAT | (cd c:/temp; tar xvpf -) I don't recommend installing and using the Cygwin toolkit unless you understand Unix and know what tar is and what it is used for.

I had this problem too, but only with one particuar VCD. It was a copy of "Howling V" that would disk copy fine, but I couldn't lift the .dat file - it gave me the invalid function error.

I believe that it is a problem with how the disk was originally recorded, but I don't have a specific reason. It happened with 4 different CD players.

The movie turned out to be so bad that I used the disk as a coaster for my drink.

there is a thchnology to stop coping *.dat file from CD to HD. the technology gives you to play it but you can't copy. the way they doing this is, insert some blank area into the *.dat file. the method of playing and copying in OS is different from each other.

the only way to copy thies type of files: CLONE the CD.
