hi there,

the "patient"

Seagate 1TB HDD
Model: ST1000LM035 ,Part NUM: 1RK172-071 , FW: LCM2

SN: WL1KPYK1

was on a laptop, did not get any hit whats so ever.
suddenly the hdd decide to die (not being recognized) , before it stoped being recognized windows 10 decided to run a chkdsk on it.

i've dissambled the hdd , and tried with a docker and a diferent pc, however the result is the same.

the hdd DO turn , do make a sound of working , no ticking , but it is not being recgonized whats so ever.

i'd like to hear suggestion what could cause the problem and how to solve this to retrieve the data on the drive .

(i've heared there is a thing called terminal lock , i dont know if this even apply to my case or full understand what a terminal lock is. t)

thank you in advance :)

I added some pictures of the hdd and its board,

Im a tech savvy know a thing or two about pcs, but never went into hdd/ssd world deeply .

I'd like to receive some diy suggestions.

Note, the hdd spins , no ticking , no noise , heads does not seems to be stuck or scratch the surface of the platters.

It just do not boot or identify or being recognized by the pc, does not shows up on disk manager or device manager, make no sound of being plugged in the pc like a normal usb .

Thanks alot in advance

I think i found the coprate

Is this possible that this resistor is dead/burn ?
Any one as a picture of a working card ?

Or maybe the resistor value so i can replace it with a working one
Thanks

My bad, this was a capacitor and not a resistor

What makes you think the cap is blown - have you done a continuity test, measured the voltage either side, at the tvs diode, probe point?

Step back and look at what the symtoms were.

Is the drive shown in your systems bios and as the correct size?

hey there , thanks for your interest.

well the burn color (black color) on the cap is what make me think it is burned . (in the last picture with the red arrow i drew )

i have done a continuity test from both sides of the cap but all caps on the board has a continuity (since they are all on the same board , i havent disconnected anything yet.)

beside that , i havent measured anything yet, since i dont know what to measure (from where to where)

on my motherboard the bios dont show the capacity of the HDD, but the HDD do shows there.

the hdd board is number , 100809471

thanks
ron.

it's a resistor btw, probably 0 ohm, fusible one. (haven't checked it on a pcb, just looked at the layout on the pics...)
But yes, it does not seem like burnt, especially because OP says the drive spins and sounds normally.
A terminal log is what could give us more insight...

how could i give u a terminal log ? (can u guide me through it or direct me to a location with a link)

where have u see the pcb layout/schematics .

i mean on this board there is smd where there is an R (as resistor) on the smd itself (if u look at the other picture)

are u sure we are speaking about the same smd ?

What do you expect?
"Diagnostic port is locked"
What else?

how do u know that ? (and how can i provide it?)

by the way, since i am a new user here each post i have to wait for aproval so i cant really answer right away which is frustrating as F :)

thank alot again for all of u for taking interest on my case

i expect a log after powerup, no need to interact with it at all.
then we will have moral basis to say something like take it to a pro :)

To the OP:
you won't be able to execute any commands exciting enough to be worth running coz the diag port is locked, ie, as BGman said, you will get an ugly (for you) reply to each command, but let's look at the bright side of this fact, namely that you won't be able to mess it up completely trhough terminal.

Ok so latest update.

Since one of my motherboard did recognized it , but did not show the capacity i took a different mobo , which there it showed the fully capacity.
But with an error showed on the picture

I was surprised so i fully turned on the pc and
Here it was the hdd was connected one of the two partition showed i started to see if i can access the data and i could, for 1 min. Then the pc kinda froze while the hdd was connected, i deattached & reattached the hdd so i could grab couple of important file which i was able to for 15 sec.
After doing that for 3 time i suddenly heared a little pop, no smoke or burning smell, turned off everything , and the first thing i noticed was that capacitor / resistor (im not sure what is it yet, look like a capacitor to me) and it changed his whole color to black.

Which i belive (again) that this is my issue unless u can guide me otherwise.

Anyhow i attached the 2 pictures, one of the error , and one of the entire black cap , which u can clearly compare it with the prior pictures :)

As Pepe says it's a 0ohm resistor (checked one yesterday to confirm). You can put a meter across it to confirm and also measure the voltage after it to check if it's blown.

Measure it and find out.

The fact the bios wasn't happy about the drive indicates there's a serious issue and you're not just going to be able to clone the drive and recover files. Have to think the best option, if the data is important was to stop at this point as you've done all the safe DIY stuff.

yeah, it looks like your posts appear apparently randomly between ours :)

search for something like 'seagate terminal connection', you will need an 1.8V USB to serial adapter for that. I think this matter is negotiated in details on this forum in plenty of posts.

that black thing is not a capacitor, it is a resistor. The discolouring you mentioned looks like something got on its surface rather than a sign of burning.
i still don't give it too much chance as being the cause of your headache.

Terminal log, please :)

pepe

What are u talking about is the TTL to usb perhaps ?
Using putty with a baud i will be able to read the terminal log thats u are talking about ?
If yes i have to find it somewhere laying around somewhere.

Anyhow , i have looked into burned smd and they look almost the same.

Note that , after the "pop" it turned all black , i guess burned completely.
It was not colored.

In anycase i have purchased 2 (incase i fuck up 1) board with the same id so i can take out the resistor and swap it .
Since i didn't knew its value so i bought the board, safest bet.

I do want to fully diy it , this why i am here.
I dont have 1k$ to spend , and the data is not worth 1k.
I do think this forum came to be to help diy people like ourself .
It is to easy to send it over , i dont learn anything from letting a shop do it.
On top of that they wont teach me anything.
One of the reason i am here is to learn .

Anyhow i will do some searching about the terminal thingy , and update you guys about the operation of swapping the tiny resistor :)

Which might take couple of weeks until they arrive


By the way , after the pop, i have decided to plug it one more time ,
It turn on, hearing the disk spin , heads moving, getting recognized (by windows sound), but no partion shows up after couple of sec 30~ the hdd turns off and back on
When it turns off u can hear the heads quite loudly because of the stop

A few things you should know:
Your drive belongs to the Rosewood family of drives. These drives are hardnuts even for pro's (at least for a part of them).
One reason for this is that they have "Diagnostic Port Locked" i.e. they can't be repaired by the com port commands.
The problem of your drive has nothing to do with its PCB. If the PCB was bad, the drive couldn't spinup at all.
DIY task looks like a "mission imposible" for the guys here. So they are prone to joke with you, not to help....

+1 for BGman.

People who know how to do it won't engage into a never ending course, those who think they know it may give you ideas.
We can check the terminal log for you and give an idea what could be wrong but you won't be able to do anything in the terminal since it is locked.
What you may try is cloning with HddSuperClone, there are plenty of references to it on this forum. But i don't recommend skipping the terminal log step...
Such job takes a few hours for those who know what to do and have proper tools, while it takes weeks to teach somebody with zero insight in the field, while we can expect drastically lower success rate. So what's the gain?
You do what you are good at and we do what we are good at.
Btw, without sharing your location we can't even recommend anybody who might be able to help you locally, probably at a fraction of the amount you mentioned, at this stage. It can reach a higher amount if the condition of the drive gets worse though.

I'll just shut up then :D I've not seen one yet that didn't have a platter looking like Saturn's rings.

You'll also need 2mm pitch connectors as 2.5 wont fit unless you get creative with the scalpel.

I have split some breakable IC sockets, soldered them to wires and insulated with shrink tube. This way i can attach to connectors with whatever the pinout is.
