WDJMWVW-11S5XSO Head swaped but error in head test in marvel

[mad4hdd]

Hi senior Drs . As i am new , I i am looking for some guide line from experts . i have a case WD passport 1TB . there was a sound like Chirr Chirr Chirrr and spins down after a few tries.... i got a donor ...matched DCM and i swapped head successfully .i converted USB PCB to SATA PCB .Drive came on ready status .I started Utility with auto detect .... it detected marvel Firebird. 0123 heads .ROm Ver: 03.52C . i directly went to Head test . but there was head error .... light blinks below some time in checking heads .rapidly ... i turned off port and de attached drive..... then reversed donor heads back to donor drive . Donor drive came ready and in head test it is going very nice smooth fine . Now i want to know what is actually problem and how can i fix it ? if i put it on imaging or data extractor will it work? or will it eat new heads ? ..... or is it microjogs story or other which i don't know till today ? i will do experiments 1st i get enough knowledge about this case ... and i am sure i will find the solution but it will ask me time .... if anyone like to share his/her experience... it will be highly appreciated. thanks in Advance have nice weekend .

about donor : pass DCM here in firebird . it's not important at all

about Micro jog . also i don't think so here

about the heads now . it's matches but may be there is scratch or bad sectors on one side of the 2 platter . you should image your drive with other 3 heads and then go for this last one . try to reverse reading or what ever , you can read from it .you may even can read in extractor a lot of data you need to take .
please here : don't be in rush when you are going inside a drive.

Wow ! 1st of all thanks To mr Tawfeek for paying attention on my post . 2nd can you tell me please is DCM exemption in only Firebird ? i don't understand exactly..... you mean we don't need DCM in firebird ? Right ? if yes ! Then what is exactly required for donor head match?
3rd i saw on upper platter there is no scratch and Drive is looking very fine from inside , maybe there is scratch in lower platter .i will check it. hopefully i will fix this case very soon . but i will need guideline from senior Drs also. thanks

[Tawfeek]

1-yes DCM is not required in firebird
2- what is exactly required for donor head match? same pcb . same head map
3- maybe there is scratch in lower platter .i will check it. how can you !!!!!

[mad4hdd]

There are two platters and if i want to check lower sides, i need to open platters from Disk assembly . Then what should you advise me ? Open platter right now or should it leave on End Step ? As i see there is no particles on filter even with Microscope .Upper platter is looking very nice and fine same i assume for other ones. 1st i am looking for Advise from experts before platter surgery , then i will do this on end if there is nothing remain

whatever you do, just dont attempt platter surgery or you will make it worse or even total loss.

what is the current status of drive ?
is it still in detection means new heads are working or gone ?

clearly you miss the opportunity to extract the data at first stage.

just don't attempt platter surgery or you will make it worse or even total loss.

I don't think so man ! I am very well aware about physical recoveries and procedures . The current situation of drive is detecting very nicely and i took data from 3 heads i accessed SA by head 1 . All key modules are healthy . Now the problem is with head 0..... i Want data from head 0 . as i mentioned before this post , the heads are good .

firstly you never mentioned that you have extracted data with 03 heads.
secondly, your above and below statement are contradicting....

No Offense:
how come you are very well aware with physical recoveries and not aware with logical/FW problems.

just don't attempt platter surgery or you will make it worse or even total loss.

well , Mr MindmergePk ever you heard there are many kinds of doctors? I tell you two major types of doctors , one type are specialist in surgery. right ? And other are specialist in medicines. physician don't do surgery cause he/she is good in medicines. it does not mean he/she is not a good doctor.It is matter where they are good . I am good in physical recovery and surgery Al-Hamdulillah. is it clear ?

[mad4hdd]

And i told you current situation of drive in 3rd last message when you asked me current status. and i told you at that time, then how can you say i never mentioned ? please check my post carefully. In 1st Post situation was different .

it is already clear to me. dont take it personal.

I know many people in DR who are very good in logical recoveries but not good in physical recoveries, am glad I met one who is expert in reverse order.

I wish you good luck, no hard feelings.

[mad4hdd]

Hahaha .. man its not reverse order. Do you know ? combination of subsystems? all subsystems make a complete system.If you don,t know let me tell you ...
Hard drive is combination of mechanical,electrical (electronics) and software ( software is end part). and these three feilds are individually separate and deep feilds... If you studied in mechanical or electronics as major? you studied software but not in depth then ? is it order ? No ... you seems a active forum member i respect you . Today i tell you one thing you will keep me remember .... Order starts from physical Thing not logical ,1st you see digit 1 then you learn or call it one. 1st company makes a drive then they feed some firmware in it .before recovery you learn anotomy and physics of a drive . what you do when drive don't spin up ? this is order. so my order is right . If you are surprised to see me as my order, then you will shortly more surprise to see people coming from multi directions and focusing on one object .... have good day
