Thank you for your second reply.
I am sorry to say that I have got things horribly wrong. You confirmed that I could not change the arrangement or file system on the disc.That was good information and will remain very reassuring.
Your answer made me examine the disc box and view the internet advert for this product.
I have included a web link showing the advert and the compilation of the discs .The disc (1) with the "problem" is in fact showing 4 files with multi tracks per file.
Disc 2 shows track arrangement as with most music discs.
When ripping I really thought that disc 1 arrangement was similar to the individual track layout of disc 2.
Then when I ripped only 4 files I thought I had corrupted the music disc.
Now proceeding to cut each music track from its file.
I want to add that in the first place I found it very difficult to assemble the problem into the written form but within 2 replies from you I was re focussed and back on track!!!!!.
Once again thank you.Your help is really appreciated.
Thanks also to the other correspondents
