I'm sorry Frank, i can't find the option on crystaldiskinfo for smart hexadecimal text dump.
Thank you for suggesting me the pcb on ebay, i couldn't find it with my research on ebay (probably i've some sort of activeted filter that ignores ebay users with bad reputation, IMHO).
I feel lucky even if donor pcb arrived faulty (as spildit thought) because i was able to make it usable once i've noticed those missing capacitors. :lol:

@labtech
i've attached picture of the enclosure and controller pcb.

I would take any failed SATA HDD with good PCB and test inside the enclosure, preferably a WD drive. If nothing gets fried, then the enclosure is likely fine.
Then can test with the Helium drive inside the enclosure.

This is the kind of info that CrystalDiskInfo produces (from the Text Copy command):

Yep, i was thinking to do that.
Tomorrow i will search for a sacrificable WD drive, just to be safe.

8TB my Book opened up but cannot install any other drives in caddy:

they are both WD80EZZX-11CSGA0 8tb Hitachi helium drives with 128mb cache
i thought that as a bonus i could use the case - caddy for some of my older drives
however no drives i try can be formatted in windows by any method apart from the original drive
i have even tried cloning the 8tb to an old 3tb but that dose not work either

Error codes aside, it has something to do with the flash EEPROM on the bridge board being paired with the original hard drive. I wonder if the flash EEPROM chip could be ‘reset’ somehow?
I finally had enough I found a working solution… If you cut PIN 8 from the winbond flash chip, you can effectively circumvent WD’s irritating firmware shenanigans. Now the bridge board will behave as a generic usb controller and you can install any hard drive you like

However, your solution does work and for me it was the first time I read about it.

yes, i've already read that post about removing the eprom chip on controller for using other drives :D

I've attached a 500 GB hard drive (WD5000AAKS-22V1A0) to the MyBook usb controller of this 8TB helium drive.
I'm using the original MyBook power supply, once i attach the usb data cable to PC usb port the hard drive spins and is detect in device management as with name (WD My Book 25DAUSB Device).
Device management also loads WD SES drivers.
I can't access to user area on normal hdd attached to this controller as we expected before, this due to the particular behaving of this type of controller.

I attached this 500 GB WD drive just for testing if the usb controller could work without damaging the hdd pcb, now that i'm sure it doesn't kill the pcb, i can attach the original WD80EZZX-11CSGA0 hard drive.
Unfortunately, original drive is detect exactly in the same way and i still don't have access to user area. :(

When i open R-Studio with WD80EZZX-11CSGA0 drive attached to this controller, it detects it as the same 500 GB hdd that i used for testing previously (with its identical serial number).
I'm thinking the eprom of this usb controller records informations of wrong attacked hard drive and somehow locks permission of identifying the original drive. :?
Do i have to remove eprom from usb controller in this scenario?
Any other suggestions for access again to user data?

ISTM that it would be prudent to backup the flash memory on the bridge PCB. You may be able to do this with an SOIC clip. Hopefully there is a reserved area which stores the drive's ID.

I would also check whether anything has been written to the WD5000AAKS-22V1A0 drive, either in the SA or at the end of the UA.

Once everything is backed up, you might like to change the model or serial number of the WD5000AAKS and then reinstall it. Hopefully this will result in changes to the reserved area on the bridge PCB. After dumping the flash memory for a second time, we could compare the dumps and locate the area of interest.

If i would backed-up the flash memory of the controller before now i wouldn't have this problem, but its normal making mistakes when we deal with new stuff. Now we've learned that if we swap hdd on this new type of usb controller we will have no more access to the original drive data, because the flash memory of the usb controller saves ID and capacity of previously attached drive and if after we connect again the original hdd, it will not save its ID and capacity.
Seem that WD now with this new kind of external hdd wants to forbid users to access to their data on the original hdd if some other drive gets attached to the controller. My god!!

I did backup the flash rom of the controller after i attached the 500 GB WD drive for test purpose, then i did the same after i connected another drive (1 TB Toshiba) and i compared them into Hex Workshop.

I don't think anything has been written at the end of UA, i checked with WinHex on the Toshiba drive that was zero filled previously by searching bytes 57 44 first, then byte 01 only.
I will do further test later, thank you.

There are two dwords that look like LBAs, namely 0x3A376000 (500GB) and 0x746F6800 (1TB). These are near the ends of the drives. I would start dumping from those sectors up to the end of the user area. Perhaps there is a key in this area?

Nothing, any key or anything else from those sectors until the end.
Probably a key would be written on those sectors only after the drive gets initialized, but initialization can't be done with this controller if hdd is not the original one (at least if flash memory is present).

I think I might be getting a little closer.

The EEPROM appears to have two copies of code and data.

Code:
    0 -  FFFF   first copy
10000 - 1FFFF  second copy
20000 - 3FFFF  unused (0xFF)

These appear to be the differences in the two copies:

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

You can see your original "Westachi" ID in the second group. ISTM we may be able to restore your original configuration if we are careful. An EEPROM dump from a working bridge would be ideal for comparison purposes.

Perhaps we only need to swap the contents of 0xEE75 with 0x1EE75 and 0xEE7B with 0x1EE7B ?

Identify Device offsets 3 - 0x7F are identical to EEPROM offsets 0x1F003 - 0x1F07F.

These look like World Wdie Names (WWN):

Code:
Offset(h) 00 01 02 03 04 05 06 07 08

0001F08C     50 01 4E EF 0A 22 7D B0   
0001F095  01 50 01 4E EF 0A 22 7D B1
0001F09E  01 50 01 4E EF 0A 22 7D B2
0001F0A7  01 50 01 4E EF 0A 22 7D B3
0001F0B0  01 50 01 4E EF 0A 22 7D B4
0001F0B9  01


    50014EEF0A227DB0
    50014EEF0A227DB1
    50014EEF0A227DB2
    50014EEF0A227DB3
    50014EEF0A227DB4

They appear to be WD WWNs rather than HGST WWNs.

I swapped contents of 0xEE75 with 0x1EE75 and 0xEE7B with 0x1EE7B but this didn't help, indeed it is worse because usb controller and ses drivers do not get loaded in device magement.
I also tried to swap entire content from offset 0xF000 to 0xF11A with 0x1F000 to 0x1F11A but it behavies the same.
Also, the led takes longer to power on.

I rewritten again the rom from the dump that i've posted few post above, now device management detects it again as WD My Book 25DA USB Device and loads WD SES drivers, also the led powers on again instantly after i power on.

I guess i've to buy a controller from ebay. :(

Just curious. Is there a WWN on the drive or case that matches the WWNs in the EEPROM? Do the WWNs match the one on the label of your 500GB test drive?

It would appear that the bridge is using copy #2 whenever it identifies as a "WD My Book 25DA USB Device". That's the copy with the HGST Identify Device data.

Code:
Offset(h) 00   02   04   06   08   0A   0C   0E

0000F080  2853 4B4B 2020 2020 2057 442D 5743 4157  (SKK     WD-WCAW

0001F080  5737 4B4B 1058 25DA 0100 0000 4B50 014E  W7KK.X%Ú....KP.N
                    ^^^^ ^^^^
                     WD  MyBook

FWIW, your bridge firmware appears to support 4 products:

Code:
VID  PID
---- ----
1058 25A5 4002 0400
1058 25DE 400A 0400
1058 25DA 410A 0400   <-- your My Book
1058 25DB 410A 0400

WWN written on the 8 TB HGST drive label is 5000CCA254DE2FDA
WWN written on the 500 GB WD test drive label is 50014EE1AD6C5342

Is it possible that there are two copies of the code section of the EEPROM, but that the data sections are not copies, but distinct sections in themselves?

Code:
0000 - EFFF      1st copy of code
F000 - FFFF      data part #1
10000 - 1EFFF    2nd copy of code
1F000 - 1FFFF    data part #2
