Hi,

Did you check if the PCB is native?

[mojimorady]

dear Datalabace

hi

yes i checked , the pcb is the original one ,
now i want to know does it need to change heads ?

regards

[dmarques]

Hi,

If PCB is native, then you should swap heads.

[mojimorady]

dear datalabace
accept my regards
i changed the head , and i screw the donor pcb , should i use the native ROM
or the donor ROM ?

best wishes
moji

1- If the native pcb does not help after heads swapping , then
2- Solder the native Rom on the donor pcb, and check, if this does not work
3- Most likely the native heads damaged the SA on the platters, and scratcded them, then
4-The case is un recoverable.

Feed me back, please

dear issam
tnx so much for your helpful lines
1- i used the native pcb and native rom (i did not change the rom ) but it makes sounds like clicking
2- i used the donor pcb + native rom = again that sound
3- i used native pcb + donor rom = there is no sound , but when it wants to detect , it makes the starnge sound

please note that the head was swapped

I faced such cases,
1-Do the native heads show obvious damage on them, especially head 0, ? (the first one from the bottom), check with the aid of a magnifier.

IF so, I am sorry to tell you (based on my experience), the Service area is scratched, and there is no method for the time being that helps.

dear Issam

all the heads were apparently ok

maybe it is one of the starngest case in data recovery field !!!
