Swapping usb 2061-701675-401 AC to SATA pcb

[seafacing]

Hello everyone, I am trying to recover my WD7500KMVV hard drive that can't be recognized from the computer. First, I want to mention that this is my first trial. I have never swapped boards before. After going to the shop for asking questions, and researching from online, I learned that I have to swap usb to SATA. After a research, I learned that 771672 match for 701675 (I found it in the forum) So, I bought 2060-771672-004 as a doner hard drive from online. It might take 2 weeks to a month since I live in Korea. Meanwhile, I am going to study hard to get this work.

USB 2061-701675-401 AC < ---> SATA 2060-771672-004

So I got the basic idea that I need to find the compatible SATA board and change the bios chip so that the board recognizes the hard drive, but I am pretty sure this is more complicated than that, so here are my questions.

1. As I read the forum, I found articles that people ask about needing to transfer two chips. In my case of 701675 to 771672, am I going to need to transfer more than one chip? ( I thought I only needed to transfer the bios chip.)

2. How do I know if I successfully did the job? Can I just know by plugging into my computer? or do I need pc3000?

3. Similar questions to 2, If I swap the usb to SATA successfully, would my hard drive be usable? or do I have to go to recover the data? ( I went to the technician today, recovering costs about 100, but the swapping pcb costs 200. So I am trying to swap myself to save up some money. I wouldn't mind, paying 100 for recovering at the store)


3. Is there anything more that I need to know as a noob?

Thank you, everyone.

You only need to transfer the one chip which is labeled U12 to make the SATA PCB compatible with the drive. However, you're very likely going to discover that the data is hardware encrypted by the USB bridge chip (most are) so you'll pretty much be stuck at that point unless you have access to a tool such as PC-3000 to decrypt the data. And no one in any developed nation is offering real data recovery services for $100, so don't even waste your time there, they're just running some crap software and will have no clue what to do with this.

What makes you assume it's the PCB anyway? I'd estimate that less than 0.5% of USB drives fail due to a bad PCB. Most often it's bad heads or firmware malfunctions.

The tech guy charges more for swapping the PCB than the recovery job??? :shock:
Now, that's a first....
Is he really a DR tech?

Here in Korea, recovering fee is really really cheap. If the hard drive doesnt have to be fixed, the cheapest extraction fee was around 100 using pc-3000. And the price goes up as you need to fix the hard drive. I heard a lot of customers from Japan comes to Korea to get the work done. South Korea is known for cheap services! I used to live in Seattle, and the only thing that I missed from Korea was cheap, good customer service (The minimum wage in Korea is exactly half that of Seattle's)

The tech guy opened up the hard drive, confirmed that header works fine. So he wasn't exactly sure what the problem was, but he assumed that he could extract the files using pc-3000 if the board was swapped to SATA. Anyways, thank you so much for the information Now I know I have to go see this guy after swapping the board!

Yeah, he owns his Workstation, works by himself, fixing and recovering data from cellphones, and hard drives. His station was legit though I will let you know guys how it goes !

I do the complete opposite: change a WD PCB is "peanuts" and that will be cheaper than the recovery itself (that could even take 1 or 2 days at best)....
