Hey guys

Thanks for the input.

Ok so firstly I looked at what was stated by TippeX + DABhand (Overclocked cpu).

So I thought Id have another go making a archive for ETQW using the default values for CPU.

Same problem even when no hardware was overclocked.

I tried another time and same problem which led to to belive what Joe Forster/STA stated was looking very likely. (The archive I have mentioned has not been burned to a DVD yet as I always check the archive making sure the extraction process is 100% and works ok before i burn to DVD)

I decided to give it another go (a last attempt sort of thing as I hate giving up on anything PC related).

And it works !! I made another archive (each time I have made an archive I have always used the same image to make the archive from as the image is ok).

I have tested the archive twice on my HDD and each time no issues. Mabey it is an issue with winrar ?? And as a result of trying to make an archive a few times eventualy it worked. I dont know if it is winrar related or not. I was going to install an older version and try with that but now its worked I wont bother.

Now I need to put the archive onto DVD so I hope after burning the archive to DVD and then copy/paste to HDD the archive still works and I can extract the image. It should be ok as normaly once I have made an archive in the past and burned to DVD its worked once i copy/paste to HDD.

Thanks for the pointers. Ill post back and let you know if the burning of archive to DVD corrupts the archive once I copy/paste it to HDD.
