Hello,

I have a Toshiba DT01ACA3000 (JAN-2016)

PCB Sticker:
PF00035
TS0242C
K1N549
01B2

PCB REF: 220 0A90380 01

I bought a new PCB with REF 220 0A90380 01 (but I don't know the HDD model).
I transferred the ROM but unfortunately, the PCB didn't work.

Could anyone please, tell which parameter have to match between the patient and the donor PCB for that drive.

Thank you for your reply,

I tried that. the PCB I bought had the same PCB number, Main MCU chip and motor controller but unfortunately, it didn't work.

Regards

1. what does didn't work mean ?
motor spins up ?
gets RDY ?

2. can you read the NVRAM from the old PCB using PC3K ?

No, in PC3K, the BSY light is OFF when I power on the drive. the drive doesn't spin at ALL.

No, I can't read the NVRAM as the PCB is not working at ALL.

@sosrecup, did you not dump/backup the ROM/NVRAM after you removed it?

My approach would be to determine why the original PCB failed, and whether there is a problem with the preamp or motor. That's assuming that you did not damage the chip with your soldering.

@sosrecup, if can't solve it on your own, I would go with @fzabkar

but as as stated above, need to know:, if the NVRAM/motor/preamp is intact

as an alternative, if you have a matching PCB (example: the donor WITH the original ROM/NVRAM)
try first a cold swap ans see what going on
and same goes here, need to know:, if the NVRAM(patients)/motor/preamp is intact

On a good PCB of those (IBM/Hitachi/HGST) you can connect PCB only and you should be able to read/write to NVRam with firmware tools....

What was the original problem with the drive ? Wasn't spinning at all ? Did you try to plug PCB only of the bad drive prior to remove the NVRam chip ? That should have been the first step as a "good" PCB would allow for NVRam dump via VSC. This would also help in determine if the problem is with for example a shorted pre-amp...

@fzabkar

The original drive has a overvoltage and I can see some burnt electronic component.
I tested the Ampere between the coils of the drive, and the motor doesn't seem to have a problem.

@jermy

the question I'm asking, is what are the matching criteria for PCB for that drive?

@Spildit

The PCB I bought works fine with it's original ROM. when I plug it into PC3K, BSY light is GREEN.
When I plug only the PCB with the Patient ROM, the BSY light is GREEN too.

But when I plug the drive, no answer and no green light (even for BSY)

If you upload hires photos of both sides of the PCB, I could show you where to test the preamp.

I think these are the +/-5V supplies.

You should measure the resistance between ground and each of the +5V and -5V test points. Compare your two drives and PCBs.

AFAICT, there is some damage to the Vcore supply in the photo. Have you tested the TVS diodes and fuses? That should tell you if an overvoltage was to blame.

So most likely pre-amp is shorted preventing the PCB from even showing its status registers.

Also if you kee the pcb plugged for a while the BSY light should change intro DRDY and DSC.

If you can't see a single register with the drive plugged to the PCB then something is "shorted" preventing the PCB from working at any level.

sometimes (in PC3K) you got no light AT ALL when "PCB only" (even a good working one) is connected, but it doesn't mean anything

hoops, actually (when you get all the lights turned off) it means its ready and "can" read ROM/NVRAM/CPs

Are you sure about this ?

yes sir (not always, but most of the time)
the way to get those green lights to normal, is to send a soft reset
a bad PCB signal = "all" the lights are light green

Ok .... Thanks for the info.

This is quite un-expected. On my "password removal" experiences i think that plugging just the PCB would place the drive in DRDY and DSC .... I will have to check it again ...

Something is not right with the way PC-3000 is processing the drive register status then ....

I did just re-test with both ARM based and older ARCH M24 drives.

When i plug the PCB (without drive) to HRT with power off i get this :

As soon as I power the PCB up i get this :

Drive stays BSY for a while like 1 min. or so and then ...

At this point i can read NVRam from the drive !!!!

It's strange that on PC-3000 you don't get register status at all with known good PCB !!!!

Again i did test with older drives and ARM based drives.
