Right it's RoHS compliant. I have already tried translator regeneration, clearing P- and G-list and translator regen.... nothing.
Probably there's a problem in the overlays, an identical (or close as possible) drive is needed to get the groups and write into the defective one. I am close to the solution, because HD unparks the heads, read some of the modules and then hangs (does NOT complete recalibration). After a few seconds READY is set but every attempt on accessing the drive in this state returns ABRT - module tables are not loaded! Then, sending the LDR, the drive COMPLETE the remainder of the RECALIBRATION and is fully functional. So, the problem at 99% is on the loadable part of the FW or can't load module table.
Which modules / groups are involved ?
Hint : scanning the system area (groups) seems that some blocks are a little slower in reading, this change clearing the P- and G-list.
Can't be a head stack / preamp problem because when functional the drive has normal operation speed and MHDD works.
After starting with LDR and initializing from the SA the drive is fully functional.
The closest drive I found is a 6K040L01 (01 not 05!!) AAA - KMGA same microcode NAR61HA0 (the loader built with that drive works) PCB A2GKA.
Do you think "cloning" this drive into the defective except the specific modules like SRV, zone table and DISK will work ?
This thing is driving me mad, at this point I MUST be the winner....not the drive

it's just for experimental purposal.
Thanks for your attention.
