Is this bad? Compression signature was 4, expected 3.

I got:
\Windows\System32\MRT.exe: Compression signature was 4, expected 3. with an exit code of 1. I'm not sure if it finished.
Is that bad?

I have the same error but on a different file. It didn't finish.

I pretty much gave up after I copied manually - and I guess the metadata didn't copy with it, and it didn't actually boot.
It's on a latest insider windows 10 build, so maybe it's something new the dev didn't expect.

I'd like to be able to copy to a subvolume / subvolume image to import though, which is what I was trying to do eventually in the first place.

You should use btrfs send and receive instead of an image. There are ways to do it over a network if you have to. winbtrfs's readme says it supports send and receive.

I couldn't even get to that point is my point. I'd have done something similar if I'd actually ended up with a btrfs volume.

I have a similar issue, except mine says 2, expected 3.

same, minen says 7 instead of 3
and I was using the latest Windows 7 ISO (August) from heidoc download utility
got this error on a .NET file, something with .nzz as the extension
and It didn't finish

It seems the python implementation does not check the signature, and only writes the value 3 for when data was not compressed. Should there even be a check?
Edit: the line is here

Hey, is there any fix to this or a workaround? Tried compressing because there wasn't enough storage for metadata (thought maybe 10gb was enough, guess not), but it crashes a Sig 1 expected 3.
