Do you hear the drive calibrate normally?
Is it taking more time to reach ready state?

Mod 0x02 shows full capacity (0x3A38602F = 976773168 - 1), so there is no HPA. The size must be coming from the ROM.

Code:

The entry for module 0x411 (???) points to ROM offset 0x3F9D3. That's module 0x0D. There is no entry for module 0x0D in the directory.

Is this a red herring, or has someone been meddling with the ROM?

Could you upload module 0x109? That should contain templates for the ROM resident ROYL modules.

Is this mod 0x411 anomaly a hack that is implemented by your tool to block SA access???

i don't know what the previous DR person did with the ROM, but i had access to SA after uploading the loader and backed them up


by the way the issue still the same after writing your Repaired ROM, so i think the issue is with writing heads

See this tutorial:

Patching ROM module 0x0B/0x20B to block SA module access :
https://www.hddoracle.com/viewtopic.php?p=19705#p19705

It is evident that someone used a DR tool to block access to SA module 0x411. I have looked at other Zephyr resource dumps but cannot find this module. I'm wondering whether it exists in your drive, and if not, why would someone block it?

I don't know how this works, but here is a thread where someone is offering to block SA access (to modules 02 & 411) by editing the ROM:

https://forum.hddguru.com/viewtopic.php?f=11&t=44040

Can you upload module 0x109? This module contains a copy of the ROM.
