How can I repair the servo error in the hdd

good question
Someone here have the answer ?
Someone here will give this answer ?
will this post have more them my msg ?
lets gonna wait to see.

Two ways:
1. Make new servo
2. Put defect tracks into P-List.

Anyway, I am wondering, how did you detected "servo errors" on your drive?

Hello,
Sometimes I think - "maybe I'm crazy" and most part of the time I think - "for shure I'm crazy"
I do not know how to read englsih and I aslo do not understand english.
Ans sometimes I can seee here one thing that we supose to call "coherence" - and this is you Dmitry.
You know a lot about disk and you also have "the proper way to treat the matters".
My congratulations to you and also my respects.

About the post - yes yes yes yes how is possible to ask about someting that you can not detect, but if you can detect - why you ask how to fix ?
This is whay I wrote the first msg.
People that know will not say "how to"

Anyway I change my mind and here is an anwser:
Has a machine that you can buy and this machine can write SERVO in all hard disks, just go to google and start to research you will be able to find

Everyone couldnot help me! Mr. Dmitry how can I change or repair the servo damage by mhdd or any software.about how I could detect the servo error I think that the oldest software can detect it

I'm sorry. MHDD can't help you. And it cannot work with "servo".

From Acelab - Sergey Yatsenko and Vadim Morozov.

"Servo fields are necessary for operation of a servo system used by the driving assembly of magnetic heads in a HDD; they serve for heads’ positioning and keeping them precisely over a defined track. Servo fields are recorded during the manufacturing process to an already assembled HDA through special service openings in its case. The openings are subsequently closed with sticky labels that read: Warning! DO NOT OPEN. The recording is actually performed using drive’s own heads in a special high-precision instrument – servo writer. Relocation of heads’ positioner is achieved through a motion of a special pusher of the servo writer using steady steps much smaller than the intervals between tracks"

Enjoy!

Hi,

Buy Servo writer and some others equipment. The cost is little as
around 2 million dollar only. (Included maintenance and made in Taiwan) Do you want the contact no?

Thank you.
