Fwd: unusual sector error in "qemu-img convert.."

[Russell Davie]

Hi Max

Thanks for the suggestion.

Downloaded and compiled 4.1.1.

However when qemu-img attempted to compress the image, the same error occurred at the same sector.

thanks again,

The only thing that spontaneously comes to my mind is a bug in the
compression code that’s fixed in 4.1.1 and will be in 4.2.0 (commit
b6c246942b14d3).

OTOH that bug was only in 4.1.0, not 4.0.0.  (git-describe tells me it
was introduced in 4.0.0-578.)

So, hm, I’d first suggest trying again with 4.1.1, and hope that works.
 If it doesn’t, well, we’ll have to see.
