Samsung 860 Evo SSD Repair- Data Recovery Lab said it wasn't possible.

Here we have a Samsung 860 Evo 1 TB 2 and A2 in SSD drive that came for

data

recovery

. The drive looks like this and the customer expects us to be able to save the

data

for him. The customer mentioned that this drive went to a data

recovery

lab before it came to us the lab wrote to the customer Hi Richard, your SSD drive has a controller firmware failure or a power issue given the current state of SSD drive data recovery tools, driver failed and above corruption issues still cannot be

repair

ed for this device which is 100% true, usually the solution for this type of issue is offline recovery, However, this model of drive uses a type of encryption that makes chip recovery im

possible

once removed and read, the chips are encrypted with no way for companies to decrypt.

Do this to prevent other companies from seeing how your units work and stealing your secrets etc. What the lab told the customer is 100% true. We can't chip data recovery for this drive, the 60 Evo, but I'm going to take a look at the drive anyway because it was mailed to us for a second opinion and I don't know what else we can do besides what you already did the data recovery lab, but we will see how we have the correct N form. Here and we have one on the back, usually we can desolder the chips and we can use PC 3000 to read the chips and rebuild the files, but for this unit it is not

possible

.

I just want to quickly look at the circuit board and it looks like this. we have flow on the board. I see a slightly burnt burnt plastic right here, it means heat was applied to that board. We see flow here. Possibly this trip was reflowed due to the flux residue we see on the board around the chip. look at this, that tells me that chip was refloated or reballed, who knows, just a quick visual inspection, this chip was not refloated or reballed, just this and N ships are clean, if we flip the board, the N ships are clean and I don't see any. physical damage to the board no BN marks no burnt components what I want to do is measure a short circuit randomly check capacitors like this one here in diet mode this one is good and this one is good we have a short circuit here what is happening in let me go to HS mode we have a zero ohm reading and we have a zero ohm reading what we have here is so short what happens if you measure this cap right here on the meter in diet mode so you can hear the beep?

Voltage drop of 0.39 which is not a short and if we go over this we have a short on this boundary there is no short here wow we have that short here also those two boundaries are in two different locations one here and one here and both they are shorted to ground that short we have a short here we have a short here wow there is no short here and there is no short here how can we solve this? Probably the chip that was reflowed or rebuilt is what is causing the problem because we have a short everywhere, let's continue with the measurements and measure the caps here, what short also if we go to ohms mode, what ohms reading we are getting zero and here we have a diet mode zero zero, zero, what about this no short and no short?

Okay, behind the board. I don't think we even need to measure the back of the board, we have enough shorts on the front of the board, okay, so we'll leave the back of the board alone and focus on this area here, how do we proceed? short here we have a short on like 10 components here and we have a short here what's happening you know what we're going to do we're going to inject voltage into any of those shorted caps and we're going to monitor the board under a thermal camera and we see what is getting hot, why don't we inject voltage right into the two caps at the top and see we're going to inject voltage into the top shorted cap and look at this, we've got something hot right on top of it. here surprisingly we have something hot right here and not the chip itself, we're going to use an atomizer and we're going to spray flux powder in this area and then we're going to inject voltage again and see where that flux powder is. it melts first so we're going to spray flux powder and in case you're wondering you can buy this atomizer on our website just log on to northface.com click buy and you can buy all your tools from over there.

We have everything from soldering stations hot air stations thermal cameras this amazing microscope articulating arm the anti glare light the ring light tweezers flux spudgers everything just add to the card pay and we almost always ship the same day right now what we're going to do is to inject voltage into any of the shorted caps. I can do it right here and then we can look at this area and see where the flux melts first, much better than the alcohol, and you'll be able to see and identify where exactly the short is coming from, hopefully. one of the covers because one, two and three can be fixed, wow, wow, do you see it?

It's amazing, we can pinpoint exactly where the short circuit is coming from. That flux powder, the atomizer, is amazing, wow. Rosen's flow melted right here due to the heat. voltage injected right here and this component or the flux in this area melted, we still have Rosen flux throughout the dust, see how we have it everywhere, but here it no longer melted, so we can identify that our problem is this component. Right here, 1000 times better than applying alcohol and seeing where the alcohol evaporates first because alcohol evaporates by nature. Now, assuming the chip has reflowed correctly or reset correctly, removing the short should get the unit working again.

I just want to see the difference between using Rosen flux the atomizer or alcohol, so if we apply alcohol like we are doing now, let's inject voltage and see if we can say that we have a problem with this capacitor, here see how the alcohol evaporates, if not You have a spray bottle, you can use alcohol, but it's going to be difficult, especially if the heat is minimal, so we're going to inject volage right here and we're going to apply alcohol right here. I can see him looking, I can see him not like Sure how Rosen caps the atomizer, but I can see him.

You see how the alcohol evaporates all over the board. It's a little hard to tell, but first watch how it evaporates on this cap, so both methods work, but for me the spray is 100 times more. That's right, let's go ahead and remove this cover. I hope that's the problem. I don't want to get too excited, but we may have a problem with our controller chip, we may have a problem with our Nan ship, or we may have a problem somewhere else on the board. but for now I know that we have a short circuit in this cap, let's put it aside and we are going to measure it using our multimeter in diode mode, the component is defective, we have it, we have the component shorted, we are going to throw away the cap and not it anymore we need and we are going to go measure the top caps and the ones that were measured for your short to see if we still have a short hopefully we no longer have a short whoa whoa voltage drop of .35 we no longer have a short we no longer have a short and we don't have a short anymore that's amazing we don't have a short anymore we don't have a short anymore no short no short no a single component already has a short, look at this, wow, I think I'm too excited, too excited, I can't wait to test the drive and see if we can recover the data, so let's plug the drive in.

I have an extension cord here. and we're going to plug in this adapter and plug in the unit right here, we should hear a tone. I have an extension cord plugged into my desk. I'm not reading anything. We see a light here, but nothing annoying. Let me try something quick. Get rid of. of the extension cord and try it right on my desk. Nothing, it's not the extension cord because I know the extension cord is good. What I want to see is if this device detects this drive. Okay, connected directly to my desktop if the device is. upon detection we will see a blue light somewhere right here, yes, right there, we see a blue light right there, but nothing, look at this, look at this, it's this drive, right here, wow, I can read the files, this doesn't may be happening.

I can't believe it, I honestly can't believe we were able to resolve the issue by removing that shorted cap even though that drive went to a data recovery lab and they deemed it beyond

repair

due to possible firmware corruption from the faulty controller. , whatever we see. in the files, let me try to open a folder, yes we did it, we're done, let me know what you think, did you have high hopes for this unit or did you consider that unit hopeless as soon as I started working on it, I hope?
