Nope ....

For me it's a 7200.12 drive stuck with partial access because of bad command to re-gen translator / loss of non-resident G-List, etc ...

I guess so assuming heads are ok and problem is only partial access due to use of incorrect commands. Read MRT articles :

Also check :

Both heads stop reading at the same point or does one head read further than the other?

As i stated. Partial access, when you reach the first LBA that can't be "translated" or in other words that translates to the wrong PBA the checksum / ECC on the sector header will not match the address that you are attempting to read and you can't get any further data even if you do skip to a LBA further ahead ...

I stand corrected, its definitely partial sector access, you probably messed up translators without considering the defects from NRGlist.

The PC-3000 have that "fork" method option to fix translator that can be very usefull on this sort of sittuation ...

Even the Salvation Data HD Doctor for Seagate have an option to deal with this (that works like "Leonardo Method" - http://www.hddoracle.com/viewtopic.php?f=6&t=196 ).

For MRT you can use the instructions provided by MRT staff on those mentioned MRT articles or if it fails you can check the entioned example of how to fix this using SeDiv and apply the same method to MRT.....

Please do tell us if you do make progress with this recovery !

Try to start different LBA positions.

Other options
Remove fast copy option
Go error handing part (pic3)
Use hard reset and power reset . And use a skip block value like 100 or 100000 .
Go timeout setting part (pic3)
Increase default ms timeout numbers. It's very useful for weak heads/slow sectors . Select hard reset and power reset.
Also u can use backward reading if you wish.

It will not work. Translator is fu*** and the drive will only read up untill a specific LBA. Nothing that goes past that value will be read as the ecc for the sector will not match the LBA that you are trying to read as there are already shifts on the translator and for example LBA X no longer points to PBA Y and instead is pointing to PBA Z that have correct ecc for LBA X (as it used to be LBA Y), etc ...
