Hello again!
I write here, maybe somebody could help me.
The patient drive is a WD10EAVS-00D7B1
ROM rev:05.ASE
Mod 0D:01.00
Mod 4F:05.AS
DIR Rev:02.00
OVL Rev:05.AS

The drive idetifiable fine as 1TB drive, no clicking or any strange noise.
I can read all firmware modules fine but when i would like to access to ANY sectors, then all sectors are has CRC errors.
I tried with WDR to clear, and regenerate translator that finished with "success"(format quick with P-list), but nothing changes.
WDR head tests are finished with all heads good result.
The strangest thing is, when the drive heads parked or the motor spins down (when i do a command for it) and i try a Medai Scan with Atola, the drive does not spins up again. The drive spins up only when i want to read something from the SA. (i have attached the screen print)
I downloaded another WD10EAVS-00D7B1 firmware from hddguru files with the same microcode.
Could anyone help me to solve this firmware issue?
Thanks for any help!

It does like a password locked drive, but it does not locked with password.....
I can lock the drive with password, and can unlock it.
I have checked the overlay modules, and there are fine too.

Probably a weak head, preventing full translator initialisation.

Or maybe suspect data in mod 32.

@saltwater, I've been analysing MOD 32, and I intend to publish my findings in due course. I would be happy to look at your MOD 32. I'd also be interested in the SMART modules (21, 22, etc) as these contain some related data.

Thank you pcimage and fzabkar
I will upload all of the modules soon!
I'm pretty shure about this is a firmware issue!
Here are two videos, with similar WD firmware issue:

fzabkar:
In the past i had a patient drive with similar problem, with corrupted 0032 module. I only uploaded an empty 0032 module to the drive, and then all sectors was accessible.

So....here it is the modules of the patient drive. The drive has "all sectors ABRT" error.

@saltwater, I'm not sure if IIUC. Your MOD 32 is not clear. It has 0x35D entries in the main list. Also, if my analysis is correct, there are 0xFF reallocated sectors and 0x25E pendings. However, your SMART modules (21 and 22) are reporting 0x37 reallocated sectors and 0x25E pendings. I don't know if this difference is significant.

Thank you fzabkar!
You had analysed the original modules, but in the past i had a patient drive with similar issue, and i fixed it with a clean (not cleared) module 0032.
I have tried to fix this drive too with a clean 0032 module uploading, but this method does not work with this drive. :?

I will try to upload 31,32,33,34,36 modules to a donor drive, and then regen transaltor with P and G-list, and after this method maybe with a simple hot swap i could see the patient drive sectors.
Is this a good idea?

Sorry, I'm not a data recovery professional. Your questions are best answered by others.

Could we see what the translator module and MOD 32 look like now?

FWIW, I believe that the G-List (MOD 34) has 0xFF entries and all but one of them are on head #0. IIUC, most of the bads occur at the same point on consecutive tracks, so it looks like the head may have slapped the disc.

Thanks for all replies!

@HDD Spaz:"try booting off different head in ram."
Do you mean, try to boot the drive, and set head map in ram to 012345, soft reset, and set back the head map in ram to 234567 then soft reset again?
I have tried it, but no success.

@fzabkar: I tried with a clean mod 32 that i attached to this thread, but no success.

Einstein (forum member) says, the smart hot swap method could help me, but if i would like to read the SA tracks, there are some bad sectors.
Today Waqas Ali will send me my SeDiv license, and i'm really curious what Sediv could give me. :-)

Not quite. Try 222222 then back to 234567.

Exactly....you don't have 0,1 in the original headmap, so why does it belong in the ram-setting!

@saltwater, does this help?

http://www.deepspar.com/blog/Head-Map-in-Ram.html

Here is MOD 0A in your ROM:

Code:
Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

0002FFB0        52 4F 59 4C 04 00 1E 00 0A 00 01 00 50 56    ROYL........PV
0002FFC0  B6 64 30 30 58 31 30 30 30 32 0B 0C 08 00 00 00  ¶d00X10002......
0002FFD0  20 06 00 06 06 FC 3F 00 7C 7C 7C 52 4B 37 45 45   ....ü?.|||RK7EE
0002FFE0  52 35 55 55 00 00 00 00 00 00 00 00 00 00 90 FA  R5UU...........ú

You can see that the drive has 6 heads, and that the head map is 0xFC:

    0002FFD0 20 06 00 06 06 FC 3F

Now 0xFC = 0b11111100, which means that heads 2,3,4,5,6,7 are present and 0,1 are absent.

1. upload all modules to donor drive
2. start donor drive with patient PCB
3. spin down donor drive and hot swap PCB to patient drive
4. spin up patient drive with it's own PCB
5. let's imaging

These five steps are work, now imaging the drive
Thanks the help for all.

PS: The donor drive is a WD10EACS with the same head map.

In which case, altering head map in RAM to 333333 would probably have worked :-)
