Subject: WD80EZZX-11CSGA0 dead board, can I swap boards? supported?

Model : WDC WD80EZZX-11CSGA0 Serial : VKJADWRX Firmware : 83.H0A03 Capacity : 8 TB (15 628 053 168) wd / hitachi 8tb helium drive dead board looks like it has a normal rom that I can swap Bare board shows full id and size worried it might have ssd Can the rom be swapped? swapped board, it started to spin but I shutdown before it could read and screw up ssd. Is this supported?

it acts like it has ssd because with just the bare board

I got DRD DSC

and full ID, size serial number everything

[t...@desertdatarecovery.com]

Just a thought, can you check is that info might be in the ROM?

[wayne horner]

fillip from ace says.....

So, first of all it's Hitachi ARM drive (yes, it is).

off topic: https://blog.acelaboratory.com/pc-3000-hdd-a-drive-in-disguise.html <--scroll down

Unfortunately it's not supported by PC-3000. So we can't to get SA access for testing/fixing something.

But if you sure that it's PCB issue - yes you can try to use compatible donor PCB with native ROM.
It's not SSHD, there is no NAND chip on the board.

Re-check all TVS(s) AND fuse(s). In my experience, these are always the problem with the new WD/Hitachi drives that are "dead." 

[Alandata Recovery]

I tested some of these and didnt find anything

which do you suggest I check

came across this interesting description of how disks are laid out

its about floppy disks

but many concepts apply to hard drives

interesting description of floppy disks animation detailed

Thats cool.

Agreed. Super neat find!

I also have some info on Seagates that someone kindly sent to me yesterday. I will forward it when I get a chance.

update

I could not find any differences between the boards.

I removed the roms and read them in

My good donor rom would read and verify

patients rom would get verify errors way out at 70%

put patients rom on good board

it gets BSY but no spin

put donor rom on patients board and it works fine drive reads and writes.

put donor board with patient rom on patients body

spins up

comes ready

but doesnt recal

IDs with wrong serial number (donors...)

says its a security locked disk detecrted

cant read sectors

so patients rom is bad?

now somehow have to try to create a good rom with the good parts of the patient rom and another.

attached the roms

emmas is bad - there are 2 copies

wayne works

if anybody has any ideas on how to dissect a rom....

I have written a tool for parsing the ROMs on Westachi PCBs.

My tool and ROM analysis is available here:

http://www.hddoracle.com/viewtopic.php?f=21&t=2549&p=20664

That same thread has voltage test points for several HGST PCBs.

I believe I could repair your damaged ROM, but my first question would be, how are you reading it? Which programmer are you using? I suspect that the programmer may be set for 3.3V ROMs (the ROM is actually a 1.8V device).

[Alandata Recovery]

I think I misstated my description...

Both boards are good... I think

Patients ROM is flaky toward the end.

Good ROM + on matching drive works fine

Good ROM + patients body does the security locked, no read, no recal.....

The verify error it gets is way out

And is like 0xC8 instead of 0xC0

So maybe the rest is mostly good

My rom reader is is GQ 4 something

It IDs the room as EF5014

My library doesn't have that

So I picked some other similar ROMs like 25q80 ish one s

I also tried reading with mrt rom reader

It won't read 2 copies that match

In fact it has trouble reading regular chips

I tried settting the mrt to 1.8v and it read all zeros

At 3.3 it read something

I tried the slowest speed

Maybe try it with freeze spray...

I need a rom Reader That will read blocks in reverse.

If I could map the rom reader as a device I could use ddrescue...

ISTM that your programmer may have killed the ROM.

[pbzcbf...@gmail.com]

Try this patched ROM.

[wayne horner]

I hope it didnt kill the rom

read my good rom the same way - no problems

reinstalled good rom on 'bad' board and it works

the bad board symptom was: no lights, not spin, no id

when i read the rom on the mrt in 3.3v mode I got
