Usually the terminal port on the board would be enough for firmware repair.

The adapter incorporates a differential switch IC (HD3SS3412). I confess that I don't understand the reason for this. I would have thought that a SATA redriver (eg MAX4952) would have been more appropriate.

Thanks for info, can you share terminal port pinout?

And another question, how to use MRT WD_USB board with new WD USB HDD?
We need data, we get it soldering points on bard
We need power, if we cant connet terminal port.... where to solder and from points????
We should need serial port data, where to solder and wichs pins form adapter board?


Thanks, sure you solve all my doubts

Hey buddy - if you try to install those drivers and they aren't showing up in device manager, select LEGACY DEVICES in the device manager to find the device and install the driver. I can pull up the page to get you exact working and screenshots, if you don't already have it figured out.

It drove me fking NUTS! They are the WORST at giving help. They have dog crap for support. NOTHING for instructions. It's beyond pathetic.

And they will give you the same crappy answer if you ask them 100 different ways. They don't care. It's "figure it out yourself" ... Reinvent the wheel. They don't care. Efficiency isn't their strong suit.

What ???

Are you talking about those MRT ... ADAPTORS ? ... It just convert USB PCB to SATA ... Shouldn't need any driver ...

My Strange experience

A) patient , 1 TB usb 3 2060 771961 001 RevA WD10JMVW 11AJGS1
B) donor 1 TB Sata 2060 771960 000 RevA WD10JPVX 22JC3T0

I replaced B Rom (donor)to A usb PCB . (Delsoldered from sata and solder to usb pcb)
MRT read (donor rom) all modules and ROM over only USB connection to computer. Also read and write module working.

I tried with A original ROM . MRT Not read modules and rom over usb connection
It's very very strange. :shock: :shock: :shock: :shock:

I received a real case today.

I am backing up Modules and Rom right now.
No Com connector. No extra things. Only usb. MRT usb parts nice work.

Ha. No -- I was talking about installing the drivers for the MRT hardware. :) And the tech support? I'd reword the question 20 different ways ... and they'd COPY AND PASTE! nothing else! lol. It was amazing.

It looks like the 12 holes on the back of the card ... is to be connected [to] the adapter. Does that transfer power ? What do those do ?

Did you guys get a manual with it?

Thanks

Those holes should connect to the pins on the drive that will allow for TTL connection. I guess that on JP2 you plug your TTL adaptor...

Examine the back of the card. Are there any power traces running between the SATA +5V power pins and the 12-pin header? If not, then the drive requires USB power.

IIUC, the patient HDD is probably a SED, in which case VSCs would be disabled.

The more I think about MRT's adapter, the more pointless it seems. AISI, the switch IC (U2) serves no purpose, in which case there is no need for U1 (its 3.3V supply).

The differential pairs at C9 - C12 violate all sorts of trace routing rules for transmission lines. For example, in order to maintain the required characteristic impedance, the pairs should be close and parallel, of equal length, and the Tx pair should not couple with the Rx pair. (Of course the addition of 4 wires by the user makes a mess of these rules in any case, but it still does not justify sloppy routing.)

AISI, it would have been much better to have connected E7x to the SATA coupling capacitors (C5 - C8), without the intervening componentry (unless the designer thought he was using a redriver IC, but misinterpreted its datasheet ???).

I can't see why the tool should have any bearing on the functionality of the adapter. It's really just a passive device (U2 and U1 are just placebos, AFAICT).

Edit: I'm reminded of Rube Goldberg ...

That's exactly what I was hoping. Yes, there are... (and thats how it appears it was used from other pictures) ... but I wanted to confirm. :)

Thanks

This is the picture that made me think it was power; there's no other place they could be getting power to the drive except through there, but, wanted to confirm.

MMk, new 'weird' news; connected the device to PC-3000 ... and D.E. says "no SATA devices attached." Does that mean that something's potentially wrong with the wiring ? Or is this not compatible with PC-3000 (if anyone has experience or knowledge thereof). Thanks again! :)

I bought one of these out of curiosity and was determined to get it to work!

Here's how I've wired it up....

And these are the caps I removed...

So I connected it up to a SATA port on PC3K with no USB power and drive spun up OK, but stays BSY.

Thought it might be my wiring or the drive itself. So checked wiring (all OK) and tried another drive... same.

But with buggering around with it, I disconnected the wire to E17 on the green block while power on....

And then pushed the red wire in and voilà!! Full ID, FW access, the lot!......

In fact, it works with any one of the 4 wires disconnected and then connected after power-on. But with all 4 connected, just get BSY.

No USB power required :-)
