Hello guys, i have this drive WD30NMZW-11GX6S1 that when turn on by USB 3.0 connection doesn't spin and only turn on the PCB led light. I open in camera and saw the heads was damaged. I swap the heads for donor drive and the result was the same. I put the ROM chip in donor PCB and the result was the same, drive doesn't spin. I put the 2 drives like original and the donor drive still working and have access to the partition. The problem is in the original PCB? Thanks for the help. Best regards.

Have you tried reading the patient rom chip in a reader/programmer?

can you post the rom img here?
however, it would be quite odd to have heads and rom problem at the same time...

i can't really see anything wrong with that rom, but i did not check it very thoroughly, just ran through it and it looks like ok.
As i said, it is not very probable it developed 2 different issues simultaneously.
Btw, do you really want to recover this drive through usb?

The last ROM module has a bad checksum. The boot block may also be bad, but I don't know how to check it.

Thanks Franc for that log, it made me check the dump a bit more thoroughly.

the boot loader segment seems to be damaged, but i could not find this version, so could not repair it.
the other problem with mod47 seems not be a real one coz drive uses the other dir where 47 is valid.

I've discovered that a ROM with the same FW version might work well enough to read LBAs on the Spyglass and Pebble Beach models.

My guess is that this may be true of other WD SMR drives as well.

Worth a try . . .

there are 2 segments with bad cs, the first one and the last one, the adaptive data is ok. So it would be sufficient to copy rom code from same version 0-4e474.

The real struggle would start afterwards i think (damaged heads and possibly surfaces).

The active directory is 0x20B (my tool identifies it), so the second set of ROYL modules (all OK) are the ones that the drive uses. Therefore any checksum errors in the previous set of ROYL modules don't matter, but I have computed them anyway.

I would suggest to the OP that he dump the ROM again, just to see whether the dumps are consistent.

Can you tell us the algorithm for the boot loader checksum/CRC?

Hello,

it is a simple byte sum added in a 32bit accumulator.

So the first and the last code segments are bad.
+1 for reading it again and compare the result.

Hello,
This should definitely work ,Even if it Involves manual work on rom

I didn't know that for the spyglass/pebble but it happens for the Giant family too (not SMR)

yeah, same fw version... but here the problem is exactly there, ie getting the same fw version. After that rom can be rebuilt coz the adaptive modules are not damaged.
But as i said, the real hardcore will start after the rom is rebuilt because of the head (and possibly surface) damage...
I can do it with safe methods if the OP is interested in sending it...

I'm almost positive that's one of the things I tried when I was writing my tool. Maybe I was analysing a bad ROM? Anyway, thanks, I'll update my program.
