Hitachi arm HTS547550A9E384 4 heads donor to patient 3 heads

[Jirbun]

Hi

I want to ask you guys is there need to disable or physically cut one head or I can replace with no change.
Also to match donor is necessary to exactly match MLC and P/N ? how about this
Patient drive
HTS547550A9E384 (3 heads)
P/N : 0J15331
MLC : DA3927
DATA:MAY 12
Donor
HTS547550A9E384 (3 heads)
P/N :0J15341
MLC : DA3931
DATA:MAR 12
PCB: same as patient
Donor
HTS547575A9E384 (4 heads)
P/N:0J15333
MLC: DA3927
DATA:FEB 13
PCB: same as patient

And by the way I tried Donor
HTS547550A9E384 (3 heads)
P/N :0J15351
MLC : DA3928
DATA:15MAY 12
PCB: same as patient
Measuring resistance of all the plus points was almost the same (only 3% different) but didn't work.

Thanks

Hi pcimage

Patient drive have one faulty head I did image from other two heads,after I replace from mention donor the drive spin and has noise like heads try to look for data then drive become ready but no id and no access to any sector.
Then I return heads back to drives and now the patient drive working again with only two heads and donor drive working perfectly.

Thanks

Do you have pc3000 or other tools?

You'll need something to initialise these things once heads have been changed from native, and to load PSHT and RDMT into RAM

[Jirbun]

Unfortunately I have salvationdata tools DC and HDD (yes,there is still something like this today) therefore I don't have support at all.
I upload pictures with some options I have, can you please explain with full description(otherwise I will not understand) if I can do it with HD doctor and how ?

Thanks

I only used it once (as a matter of fact I "TRIED" to use it) (TV for someone) and if I remember correctly, the option mentioned above (uploading into RAM) doesn't exist

Again I'm not sure and I don't have it either(gladly), to check it out

Edit: just saw the screenshots you have uploaded
Can you upload a screenshot of RAM operations ?

[Jirbun]

In RAM operations there is only one option "read ram" .
Can someone explain in general on this procedure,in what cases it should be applied ? is't just for the arm series ? is't because different MLC and P/N ?

That's what I thought
You might consider outsourcing it, or buy PC3K and its not for this case only, you're gonna jump an innumerous level compared to hdddoctor (whooppss i mentioned the word compared between hdddoctor to PC3K ?)

You can get away with a close P/N MLC
but if you wanna try then...

I appreciate your help jermy,I didn't see a way for people without ace equipment to access pc3000 blog,any idea how can I read this article ?

I found another link without the need of login

But why say that I have a problem with translator if with original heads the drive recognized ,does not make sense to say donor heads not match ?

It is the case though.

It happens in a lot of "ARM" architecture Hitachi drives.

Call it magic call it whatever you want, this is the fact
I don't know the reason and as a matter of fact I don't care, you upload those MODs into RAM ID the drive and bums start imaging
