hddscviewer pass 1 pattern

[unleadedblues]

When using tools like ddrescue or hddsuperclone what is the explanation for the attached pattern after pass 1.
Doesn't seem like 1 or 2 bad heads becuase the proportions would not be right, correct?

It looks like there was a recount of the translator.
For example, this is a seagate, on which BSY(led СС) was corrected via the terminal...

The drive was clicking and not recognized.
I swapped the heads and got this pattern.

It looks like you gambled and lost.

I'm not sure what a "recount of the translator" is.

But, I am curious about what type of failure could cause this read pattern?
