I checked Mode 02
Cannot read BY ID

COPY 0 starting with xxxxxxxxxxxxxx
COPY 1 looked ok.

I rewrited good m02 over one, but I dont remember which one have been writed by good m02. I guess rewrited copy0

Now there is no good mod 02 even ID, Copy0, copy 1.

I afraid rewrite it again. I couldnt decide which one is good copy.

Also there is no mod 11 except LDR file that I found.
and I couldnt see user data .

Need Help and advices.
Is it firmware problem or necessary to swap head. And which way should I follow?

Modules and log attached.

Why don't you swap heads?

i think you should swap the heads.
if 4 heads ok and rest of others heads are not working mean, there can be filter damage or platter damage or residue inside.
sometimes all heads have poor reading since HSA has an error like preamp.

so just try to swap the heads and check filters and other.

I am searching and waiting for donor.
Thanks for response

Changing the head block should be the last option and probably will not be the solution in this case.

As far as the op comments nothing indicates that the problem is heads (although it can be), but before changing the block of heads would look at other ways.

It is a shrek LT (SED)....... mod 11, 31, 02.... cannot be read..., well, nothing new on the horizon......

SED ?
I should consider this info. I had read ROM from USB PCB (patient), and writed to Sata PCB.
Patient hdd dropped case. I guessed head issue. I am researching a cheap donor still.
