Someone has played with the drive and... touched the 'untouchable'. Or the fw is screwed to death. Or pcb is non native. Or a mix of all these options. Latest idea : bad heads , but math doesn't add up with this log.

Hi,

What do you mean by the HDD was identified one time?

[hddguy]

Did you try to restore age to 50? Also looks like H0 has some problems.

[BlackST]

...and then why it it was not 50?
