2TB Sadle G6 strange behavior

[einstein9]

Dear Experts

i got this WD 2TB case where all modules are OK, heads are OK everything is OK
Except i cannot access any sector NONE OF THEM.

- tried hotswap to even see any sector (none same issue) and my donor is luckily same ROM ver. same Family same HM
- tried another pcb (same issue)

attached is the Log
Hardware modules checking
SA structure test

i got so sick of it really, never had such a case like that.


Client said: was working, and power went off, then hdd did not work after

any clues here....?

thank you

But how sure are you that all heads are OK....

But how sure are you that all heads are OK....

Bingo!

[Tawfeek]

correct me if i wrong, there is no tool can tell you definitely if the head is totally ok even if the head can read & can write

[dmarques]

You don't need a tool for automatic testing of each head, as there are ways to check if they are working fine or not.

Also, from my experience, Sadle drives are very tricky.

At least one of the heads is weak/bad......

There is....It is the tool you use to exchange heads...That tool will "tell" you if the heads were really ok or not ...

Also, from my experience, Sadle drives are very tricky.

Correct.

thank you guys for the comments here

Heads been tested with 3 Diff. tools with the same result.

anyway, i got some PM`s here will try it and see how it goes...

Thank you all

I'm interested to know what tools/methods you have used to test heads with, because from my experience the symptoms you are having are normally indicative of a bad head which could be pinpointed very quickly in 3K.

Try to edit headmap in ram and soft rest, then modify to original headmap again.
All sectors should be accessible but the weak heads.

Do you think he didn't try that yet? Like was said before , this drives are tricky , need another method to play with them.
I am pretty sure some head is "weak" .

Very easy to swap heads with these guys.

Agree, perhaps the easiest step of the recovery.

Case Done, luckily.... was the 1st. time with me with the help of the Unknown PM guy....

if he wishes, i can reveal his ID, if not, then will be underground like the others here..

Many thanks for this TIP, i never tried it, specially with my Lovely Tool.

Yes. I do. Of course we know it is because of Weak head(s). I used to clone the data with good heads then swap heads to clone the last data on weak head. If he had tested it, I think he could get partial data from this driver and wouldn't ask it.

with all my respect, YOU DON`T

i`ve tried almost everything, and as Dr.Kiev said since i know him very well , he knows how do i think..

and this is Sadle G6 issue, which was my 1st. case problem facing here.

Sorry for I had doubted you have tried.
Actually, this is a common sympton for Sadle G6. Both the Capacity and ID are correct , no clicking sound.
All modules are okay ( the 2E and 6F is usually bad), but the sectors are not accessable even clear module32 or fix slow.

And I am sure if you swap headmap to eg (2 3 3 3 3 3) then soft-reset and change head map to 2 3 4 5 6 7,
you can access the data, and will find a lot of bad sectors on certain head. The head(s) is(are) weak.

did not work..
and thnx for the tip my dear

[Nick_CT]

The question is, was a head swap required...

A, NO..
