The "used space" and "whole space" checksum errors are bogus. Segment 2B contains SMART attribute data.

No, the data is OK, but there are no checksums. PC3000 is wrong.

Ok that means. The heads must be incompatible

No.
It means PC3k gives false negatives.

Use F3RomExplorer to extracts those segments to a file, then analyse the files with a hex editor.

Do the new heads still work in the donor drive?
May 16th, 2024, 4:58
the error means drive can read servo fine but cannot sync on sector, on both sa copies, which suggests it is looking at wrong location, which typically happens if rom is not native or head map is screwed.
Or both heads are weak, but i consider that having less chance.

Yes. They work flawlessly!

I would say this is a typical issue of scratches to the surface that preventing heads from loading SA.
