Disabling head for Seagate drive

[raf-pl]

Dears,

I had to replace the MHA due to bad head for Seagate ES.2 ST3320620NS FW:3.AEG.
I could not find the exact one so I decided to try with ES.2 ST400620NS FW:3.AEG (same firmware, different capacity).
I have noticed that the donor drive has 6 heads respectively 4 for source drive.
After replacement procedure the drive is knocking. I suspect that I had to remap/disable additional heads, but I don't know how to do it.
PC3000 doesn't detect the drive. I can see only F level onto terminal.

Help me please,

Best regards,
Rafael

Actually, I am fairly certain that the drive *Should* Still function even with the two extra heads present. The head map in your drive does not realize that two extra heads have been added, and assumes the 4 heads assembly is still in the system.

I would check elsewhere for the source of your knocking. What is the terminal output that is being given? Can you post it here?

I think those drives are ES.1 not ES.2
You can use HSA with more heads and it should work
I'm also not sure how ST400620NS drive can have 6 heads while having two platters (or 4 surfaces) in use, probably some of the heads are bad and this causes the problem

Just wondering wether the preamp could be different...
But such difference does not neccessarily make it click...
