WD20SDRW-11VUUS1 BAD

[Rames Lopes]

Hi my friends, I have this WD WD20SDRW-11VUUS1 with PCB usb board 2060-800067-001 REV P1, it has a failure in the PCB on the usb I think it was cracked, when I press the USB by hand it turned on the led turns but it clicks read head and stops rotating after 3 seconds, I did another test using the pbc UNLOCKER sata board, the disk turns on and turns and has read head clicks and stops rotating and does not show the model and serial number only size 0.

follow the attached rom, I would like to know the serial number of that rom to see if it was changed or not and how do I transform this pcb board into sata which points I have to solder and which capacitors have to remove

There is no serial number in the ROM.

Measure the voltage at the junction of the fuse ("S") and TVS diode. If you don't see 5V at this point, then reflow the solder at the fuse.

Do you have a 800065 SATA PCB so you can at least check if its head failure. You won’t be able to access data as the encryption is in the USB MCU.

hi my friends, I tested the fuse and diodes and re-soldered them but even so the board did not turn on and apparently the electronic components are good to see that on the usb input side of the board it was breaking and closing short remove the solder on one side of the usb pins and I did the test making a connection between the broken part and the tip of the multimeter follow the photos and videos, I have SATA unlocker 800065 PCB card
i need the rom unlocked, the voltages found on the fuses and diodes above 5v on the diodes on the bottom +16V and -16V

To me it looks as if the drive was dropped while the cable was plugged in. I would expect that soldering a bridging wire over the crack should fix the power problem.

[juan van der meulen]

I fixed many of these models with the same problem, if heads is good just swap ROM to the same USB pcb no need to hunt for a expensive Sata pcb if you dont need it.

Unfortunately Juan this particular drive has encryption in the USB PCB MCU. So just swapping the ROM will not work, you need to swap the MCU as well. So fixing the original PCB is the best initial course of action.

Olá pessoal, fiz uma conexão no local conectado aos dois pontos da placa, ela acendeu no início, mas fica com ela no lugar e gira e clica por 3 segundos e para de girar.

As imagens quando as imagens podem comparar com outra placa que tenho usb 2060-800067-001 rev p1 e notei que 3 componentes estão muito quentes mas o álcool está bem quente ou o álcool evaporando o álcool demora.

na lateral da entrada USB como duas pernas usb e me enrola 0,36V e em outra esta voltagem só funciona 00,00v e no transistor na sua base encontro 0,06v e na outra perna 0,70V

na pcb bom atendendo 1,22 na base e 0,29 na outra perna deixando o pcb ligado no hda ou desligado após 1 minuto aparece como desconhecido mas disco sem rotação

deixando o pcb conectado no hda ou desligado depois de 1 minuto ele aparece como desconhecido mas disco sem rotação

tenho PCB sata unlocker compatível para este disco alguém poderia desbloquear a ROM para eu testar os cabeçotes adicionei fotos e vídeos

Hi guys, I made a connection in the place connected to the two points of the PCB, it lit up at first, but it stays with it in place and turns and clicks for 3 seconds and stops rotating.

The images when the images can compare with another card that I have usb 2060-800067-001 rev p1 and I noticed that 3 components are very hot but alcohol is quite hot or alcohol evaporating the alcohol takes time.

on the side of the USB input as two usb legs and coils me 0.36 V and in another one this voltage only works 00.00 v and in the transistor at its base I find 0.06v and on the other leg 0.70 V

in the pcb good meeting 1.22 in the base and 0.29 in the other leg  leaving the pcb connected to the hda or off after 1 minute it appears as unknown but disk without rotation

Hello everyone, I made a connection in place connected to the two points of the plate, it lit up at the beginning, but it stays with it in place and turns and clicks for 3 seconds and stops turning.

The images when the images can compare with another card that I have usb 2060-800067-001 rev p1 and I noticed that 3 components are very hot but the alcohol is very hot or the alcohol evaporating the alcohol takes time.

on the side of the USB input as two usb legs and it winds me 0.36V and in another this voltage only works 00.00v and on the transistor in its base I find 0.06v and on the other leg 0.70V

on the good pcb attending 1.22 on the base and 0.29 on the other leg leaving the pcb on hda or off after 1 minute it appears as unknown but disk without rotation
leaving the pcb connected to the hda or off after 1 minute appears as unknown but the disk does not spin

I have PCB sata unlocker compatible for this disk could someone unlock the ROM for me to test the heads I added photos and videos

The transistor is merely an LED driver. When the collector voltage is low, the LED is on.

I don't understand where you are measuring +16V and -16V. Are you referring to the two diodes adjacent to the 470uH coil near the motor contacts? If so, then these voltages are as expected. I suspect they are the supply voltages for the piezoelectric microactuator.

[Rames Lopes]

yes the voltage of +-16v and close to the motor contact is really correct
where do I find

 piezoelectric on pbc board

Sorry to make an off topic question.. I've been off datarecery for a while and forgot how to find the WWN in rom.. can someone simply explain it to me again. Thanks

Search for the 50 01 4e

In hex

That should lead you to the number

If this is ROM module 0x0D with wwn number 50 01 4e im probably quite slow .. i can't see these numbers there. But I don't know how to open module 0x0D either. But now we're derailing a bit here

You appear to be having a brain fart. Search this page for "50 01" in your browser.

its hex  50-01

The first section is the address

next is the byte values in hex

Next section is the ascii interpretation of the hex bytes

Putting it  together

This shows that starting at byte address 000000:

Contains hex data byte 52 4f 59 4C...

If you look those bytes up in an ascii chart you find that

50 = 'R'

4f = 'O'  59='Y'  4C='L'

In the next row At address 000010 you have 30 which is ascii  '0'

The the next row beginning with address 000020 you find 50 01 at byes 2E and 2F

Those bytes continue in the next row

So the WWN for this is

50-01-4e-e2-69-60-94-78

Mod D is a ROYL module identified by the 'ROYL' signature

and D in byte 08
