Help needed: WD10EADS-00L5B1

[pninja]

Hello,

I have a WD10EADS-00L5B1 (Kermit) HDD which has some corrupted modules including
loader module. If you have resources of the same drive please share it with me.

Details:
Model: WD10EADS-00L5B1
Date: 20 APR 2009
DCM: DANNNT2CFN

Firmware: 01.01A01
Firmware version: 000500C5 (I need modules of this version)
(My donor drive dated 23 March 2009, has firmware version of 000500C2 which in not compatible)
Please have a look at attached screen shot for more details or for any possible advise regarding
recovery of data from this drive.

Thank you
Pninja

can you read sa tracks? if you can, make a full backup of BOTH sa heads. if you send me the backup i can see if it is possible to extract the modules.

Good Day
i have also same problem with same model Drive firmware version 000500CE .

[TerraNova]

Some heads are faulty

[swersig]

agree with terranova. but backup of sa tracks could be possible. extraction of modules is neccesary for hot swap.

YES, I have full backup of SA tracks on both SA heads.
Do I have to send you all tracks?

[swersig]

yes. in case of single sector defects in sa i need both sa backups. it just increases chances. can you send me donor sa backup as well (i mean both 000500C5 and 000500C2, for my database) ? zip file would be preferable.

Hi TerraNova,

Head test says all heads are OK.
I believe we can trust it

Hi,
You are lucky guy. I think I have all modules of 000500CE version.
If you need them let me know?

Ok. I'll send you Zipped tracks of patient and donor tomorrow.
It is late night here and I don't have access to my database right now.

[swersig]

ok, i'll see what i can do to help.

No, you can't.

No, you can't.

WHY?

[jono-ats]

You should ask Ace Lab this question. I have my own theories.

Suffice it to say that sometimes heads will pass the heads test, but you still cannot read customer LBAs. If a head passes the test but doesn't function in Data Extractor, then it is bad.

No, you can't.

On this type (green label), head swap is pretty easy. So I did a head swap today.
Unfortunately, nothing changed.
Original head also worked fine on donor drive.

In very very rare cases I have seen a faulty head passing the tests.
That is why I normally trust the head test until I have no choice other than
the head swap.

Start in kernel mode
Do head map edit on the fly - turn off all but #2
Do soft reset
See if you can get drive ID
See if you can access SA

(may have to exit utility & re-enter w/o powering off to access some SA features)

Hi jono-ats,

I don't say that head-test algorithm of ACE lab is absolute or perfect, it just helps
me to decide the head-swap as a first or last action in my data recovery process.

As to your example, I think you didn't choose a good example in this case. Head test
routine tests heads based on their physical parameters, while accessing usre LBAs in
data extractor involves logical parameters and translator tables too. Failing to access user
LBAs doesn't mean a faulty head necessarily. Please correct me if I am wrong.

I did it. Drive ID or SA was not accessible.
Anyway, thank you for the hints.

Is very easy case , easy drive , heads works , only you need some commands to get all the data back.
PM if you interesting.
