Right then, here's goes my further attempt to confuse everyone (including myself)
I rebooted the PC.
Did not start my file download.
Turned off my "DigiTV" software that sits in the system tray.
Transferred the .ISO data file from my external drive onto my internal drive.
Rather than double cliking on the ISO file to launch Nero, I ran NeroStartSmart and selected the burn image to disk option.
And the result?
Due to the reader, forget the fact that the lower green graph is quite solid. It's just the way this drive reports errors.
Also, I know (for some) the blue "PI" errors are a bit of the high side, but I find this is normal for this media.
To show you this was not a fluke, and the above image is "VERY" typical for these Blanks, Here are 2 more scans I did with the same burner and disk blanks very recently.
Amazing how very similar they are:
Almost spookily similar scans all 3 of them !!!
quality 93 and PI errors hovering around 200.
Which begs the (original) question:
Why did those other scans go so bad one after another?
And also, how come I had exactly the same happen a few weeks ago (albeit the bad red errors were about 60% of the way thru) when I was using a Different burner, and also Different media?
A Puzzle, don't you think?
The reason I'm using the reader is the Pioneer 112 is an unknown when it comes to reading, and my reader "LiteON JLMS XJ-HD166S" whilst not great, does seem consistent and my old scans are done with it, so I have something to compair with.
I'm getting the new 20x LiteON burner next week as my drive to do readings with as it seems to be a forums favorite.
