Thanks for the responses. And sorry about not posting full log, I did not keep it. I just finished another burn. Here is the full log.
And also ImgBurn gave me the following error once, during writing:
Hit retry once and it was all good. I've never had a burn fail me. I can still access M:\helloworld.wav, and M:\helloworld.sfv checksum is ok (even though it takes about 25 seconds to complete).
HD Tune, I had not thought of that...
Any more info that might help, I will post. I got this drive brand new just over a month ago. Using sata2, and cable is good because I reused the one that was connected to my old hard drive.
