I'm fairly familiar with everything you say but I would like to know the
correlation between these two diagnostic tools, wherein they are giving
large differences in their reports of the correctable errors of the same
disk.

Without knowing what drive you have and what exact tests you are
doing, it's impossible to say. No 2 drives report the exact same
thing as far as CD errors are concerned. Total C1 counts are
meaningless, it's the graph itself that matters. Average C1 counts
and max values also help interpretation.

As to C1, there are no specs for these, and no upper limit has ever
been documented that interferes with reading a disc. C2 errors are
bad, there should not be any, but again fairly high C2 levels are
often tolerated. C1/C2 are speed-relative, the faster you scan the
disc the higher the levels will be.

Suggest you drop by http://club.cdfreaks.com/ and read up on error
testing.

in my nero cdspeed tool, an audio cd check reveals about 1500 c1
errors and 0 c2 errors.

I downloaded and tried cd/dvd Diagnostic by infinidyne and its
analysis says there are 200,000 plus 'soft errors' and no hard
errors.

How is this to be interpeted
