Hello,
I have a HTS723225A7A364 drive, it calibrates, gives ID, both heads read and write in SA well, but only H1 can read LBA. I get UNC on all sectors on H0.
It's strange as it reads and writes without problem in SA, also there were some differeces in PSHT module on both copies, i tried to rewrite copy 0 to copy 1 but the result is the same.
I also tried to clear the Glist.
I have not tried heads swap yet as I think it's SA related.
Does anybody have experienece with this kind of error?
Thank you.

Most likely unstable head 0
