Calypso head stack replacement

[areus]

Hy!

Can i have a question? What is the difference between a K,M,G,A Maxtor drive (6Y080L0) and a K,F,G,A drive (6Y080L0 too)? I know the first two must be same for a HS changeing, because this two means the head type, and the preamp type....but i had only this donor drive .
The type number (6Y080L0422011), and the preamp was same.

I changed the head stack (the first had a wrong peramp, the second had an absolutley unrepairable SA-A & SA-C). The first load was OK, good recalibration. (no click, etc).
The drive had two partition, every part was full with data. SMART was very good, the drive had only 4 reallocated sector in the middle of the drive. So i saved the whole data (that was my goal ), than i tried to erase the drive. First i cleaned the MBR to delete the partitions, then zero fill...

But now after the erase, the drive spins up normaly, recalibrates later, then lot of click and seek noise...and some long seek noise (like under recalibration).
I take care of the plater & heads under the head changeing. No dust, no fingerprints.... (I used some compressed air to clean the plate from the very small particles)

Is it possible the head type was realy wrong, and the erase destroyed the drive?

I cant belive it!!!! I had reallign the headstack, but i forget the case's screw can make it wrong ....

Huh? The screw fixing the cover onto the head stack post misaligned it?
What was the use of erasing the disk after recovery? I would be quite lucky when a head swap worked without the proper environment (did I get anything wrong? compressed air wouldn't be necessary when done in a clean cabinet or room) and I get the data back, there wouldn't be any reason to try to make the drive usable again.

Hy!

The head stack has a little torx screw, what fixes the bearing in the head. I used this screw to locate and align the head. (the donors head was too high located in the new drive ). So i lifted down the head....put back the cover and the 7 screw...and go. I cant understand, how was the data readable, when the head was upper. (maybe the bearing was shorter than the original...) And one thing: the cover is not flat, like the original drive. It has a little decompression by the bearing, maybe it pulled by the screw.
I used Victoria. (i heard later, this prog is not the best to zerofill the drive....)....now i had locate normaly the head, and works fine, but the drive has lot of UNC... . Maybe the disaligned head worked well.
I havent clean room, or clean cabinet.....only closed windows, closed door, cleaned tools, and clean place .

Hi,

I suggest, to don't do write operation with changed headstack!
Only read it, and place between the other parts in the stock.

Thank you, Janos!

...i had realize it. I had save the mods, a good loader (i havent any KFGA donor....so it will be usefull by a new ,,bad" drive).
But this drive was intructive for me.... I found a module with ,,PowerMax II" header and a module with ,,REFURB" header.... (on the cover was nothing, like ,,Refurbished to Maxtor Specifications")
