The good side - it is a conventional (no helium) disk.
The bad side - this is a drive that is not supported by PC3K...
The disk is detected correctly (ID, capacity, FW, etc.).
Unfortunately, there is no access to the data area - ABR error ....
Because PC3K does not support this family of drives - I have no way for deeper diagnosis of this case (SA and others) ...
I don't know what the Tech Key is for this family.
The PC3K detects it as the ARIES-KP family.
Based on the interview with the client, the drive was not exposed to any impact (mechanical) factors...
Except - there was a moment when someone else had it and used it for several hours.
The disk "died" slowly - over several days.
First errors appeared, then problems with copying - and finally it "died" ...
So it rather indicates - that some slight "impact" factor has occurred...
After the first "inspection" - something about the boot sound of this drive made me disturbing...
I asked the customer if he had another, the same disk.
Fortunately, he confirmed ...
This drive was bought together with several others - the same.
The same twin disc was delivered to me.

I compared the "sound" (acoustic) starts of both disks - and there are some differences.
In the "sound" recording below, I show the start of a healthy (donor disk) and patient - for compare it:
(ATTENTION !!! You have to turn the volume up to max !!!)
I did notice a difference - for comparison - the start of the damaged patient disk (from about 11-12 seconds there is a change and "other - more" clicking of the heads):
Also when running in Universal Utility there are differences:
To illustrate, i show the start of a healthy disk (donor) in Universal Utils:
- Donor - Universal AT Utility message - immediately after turning on.jpg (7.13 KiB) Viewed 3900 times
And - for compare - this is, what it looks like when trying to start Universal Utility patient disc - after powering up and trying to start right away:
- Patient - Universal AT Utility message - immediately after turning on.jpg (223.99 KiB) Viewed 3900 times
As a curiosity - i will mention the fact - that the "patient" disk after starting (for several dozen minutes - every few - several seconds) something "cracking"...
As if it was trying to read something ... After this time (several tens of minutes) - these sounds is stop and when i try to enter the Universal Utils - shows messages with fewer errors:
- Patient - Universal AT Utility message - 0.5 h after turning on.jpg (6.98 KiB) Viewed 3900 times
--------------------------------
IN SUM.....
--------------------------------
I haven't opened the drives yet.
I don't know how many heads it has and what condition the surface is in.
But - my experience tells me there are probably two options:
1). Damage to at least one of the heads (except the system one) - and the disk does not load the translator.
2). The Heads are good - but the translation modules are broken... This is the worse option (because without the ability to edit SA I can't do anything else)...
But in this case (nr 2) the question arises - would it show the correct capacity of 6 TB in the ID ?
---------------------------------
ASKING FOR ADVICE...
---------------------------------
My question is as follows:
Is there anything else I can check before replacing the heads ?
Theoretically - i can read the ROM and extract the NVRAM... But is there a tool witch to check, edit and correct the checksums in the ROM of this model ?
But will disabling the heads help me ?
Will disabling the inoperative (defective) heads will load the translator and will confirm the damage of the heads - while confirming the efficiency of the translation modules ?
I need data from all surfaces (Long "heavy" AV files)....
Thanks for the answer.
Regards, Igen.
