how do you manage this

[positivebit]

If you have changed heads already for new set did you modify NVRAM to allow access with H0 only? To check if you can at least read SA from surface with new HSA?

not on this drive, but in another one that have only one platter and a scratch on top surface i would like to modify the nvram.
i think i get the position of head map in nvram, i saved 01 into 00 but ... still i miss something.

btw, pencil signs:

Hitachi usually have some pencil marks on the edge of the platter, but you break the alignment if you remove one platter only...

Wich model it is exactly?

hi i made alignment reference in another place. you really want to try to recover this drive? pm me..

I have a lot of techniques for hitachi, i can do almost anything magic on this drive.
I have made partial successfull recovery from similar condition drives before...

Well, i can try, if the case is really important and the client have tonns of money for his data.
