Adamant IT yes you can see them in action @electronicsrepairschool

[@guytech7310]

A better option to remove smt components is with a hot-air rework station. Basically it produces a small stream of hot air to melt the solder so you can remove it. Alternative you can use solder wick (braided copper) to remove solder from the PCB and component so it can be removed. That said the hot-air station is the preferred tool to rework PCB boards.

[@jafinch78]

I've seen there are ~$15 solder iron tweezers online now on eBay and I assume Aliexpress. I ordered two additional SH72's with some J style tips and printed a holder on a local fab lab 3D printer to make portable tweezers. Haven't gotten around to assembling yet, since don't have the need. I'm still working on outdoors projects. Am planning to either use PlastiDip or Type 2 silicone coating on the 3D printed part also to seal and provide a little better grip. Thanks for sharing... makes me want to check my bin of HD's to see what might still have some life left.

Hey adamant IT. Quick question, if I have a 1080ti where 1 fan might be shorted, and the card only shows black screen when booting, what options do I have? Have disconnected all fans, but it wont boot. Is there something I could swap out or check with a meter?

[@guytech7310]

@@runehansen278 If the fans have three wires (speed feedback), its possible the card will not run with the fans disconnected. One option is to try running the fans (12VDC or 5VDC depending on fan voltage) to see if they work. Also check the fan power pins to see if the card is supplying power to the fans.

Hello there! I know we don't know each other, but I wanted to let you know, that you saved my memories of over 12 years I already thought were lost. I had a similar HardDrive which did not work anymore and I thought let's give it a shot. Fortunately I already had a multimeter as I started a little with microcontrollers and Arduino. I then watched another video on how to set a multimeter to continuity mode ( I am a nooby with electronics) and had the same issue. This is why I love the internet. Anyway I just wanted to let you know that you made my day! ❤ Dankeschön from Germany 😊

[@MrCalifornium]

Massive thank you for this guide! I found myself in a similar situation with my backup drive failing to spin and a short on the 12v line. Informed by your content, I ventured to remove the diode, and to my delight, the diode was shorted out of the circuit and... I'm now successfully recovering my data! As someone with minimal experience in electronics, particularly with circuit boards and soldering, I was initially apprehensive. However, your clear explanations and practical tips made the process not only achievable but genuinely enjoyable. Channels like yours are a treasure trove for novices like myself, empowering us to tackle technical challenges with confidence and enthusiasm. Your work is not only educational but truly life-saving regarding data recovery. Keep up the fantastic work - you're making a significant impact!

[@tunkunrunk]

where and how did you find replacement diode ? can you find a compatible one in any old devices pcb ?

[@danarepouille1381]

@Adamant_IT Thank you, Graham! I received a laptop yesterday, which would not POST when the SATA 1TB Seagate HDD was connected. I removed the HDD, removed the PCB from the HDD, and checked for shorts. The 5V rail was shorted all over the PCB. I injected voltage, starting with 1V and 1A, increasing to 3V and 1A. The diode got hot, which caused me to remember YOUR video! I removed the diode, and the HDD worked perfectly after I reassembled it and connected it to the SATA port. Since I have no use for this HDD, I did this purely as an experiment and for my training experience. Thanks ever so much for planting THIS video into my brain for future use, two years later.

[@dekeonus]

Just a heads up (to viewers and author alike), @14:01 DO NOT write to the actual disk! That is very bad practice: If there are deeper faults with the drive you may make the drive forever unrecoverable. The customer will be less than happy if any future attempts to recover data (by say a specialist lab/company) are thwarted by your inadvisable write to the failing drive. What you actually want to do: perform a sector by sector copy to a doner hdd or image file. Testdisk will also work against an image file (the linux and windows versions have been used this way by this commentor)

[@iDork56]

I'm so thankful that you decided to make and upload this video! While I did not have issues with a dying diode, I DID have a drive that dumped it's partition table mid-backup. I lost ~8 years of music collection from various audio outlets, some of which are now defunct. CGSecurity's software managed to find the partition table, re-write it, and allowed me to recover all of my music again! I've only been subscribed for a short while, and you've definitely piqued my interest with these oddball repairs. Thank you so much!

[@vitor900000]

4:45 You could have also talked about rust accumulation over time here. Right above you left hand finder are the contacts pads that connect the board with the HDD head. Overtime those pads can develop a layer of rust (Your HDD already have some. Its that yellow discoloration) and this can cause the HDD to have a lot of R/W errors. This can make a HDD look like it has bad sectors or is dyeing but in reality its just a bad connection between the Head and the Board. Cleaning it can bring the HDD back to fully function. Saved 2 Seagate 2TB HDDs by cleaning it.

[@vitor900000]

@Mr Guru There are many types of rust. Its defensively rust just not the usual green/blue rust that you usually see from water damage.

[@duroxkilo]

very interesting.. it's also visible around the 3 screw holes @4:41.. what causes oxidation to occur gradually like that?

[@vitor900000]

@@duroxkilo As far as I know the type of rust that aren't chemical are related to heat, humidity, and oxygen concentration and the type of metal. Also the flow of electricity can accelerate the process. Oxidation will happen overtime to all metals. Some are more resistant than others. Aluminium for example is very resistant to oxidation because it rapidly form a thin aluminium oxide layer that impedes the metal from entering in contact with oxygen. For those kind of applications the best metal to use is Gold. That is why Memory and CPU terminals are usually Gold plated. Gold is very resistant to oxidation and a excellent conductor but its also expensive. Idk what metal they are using to plate those terminals but due to their color its definitely not gold.

[@Umski]

I had a TVS diode go on a WD from my parents' PVR which had a PSU pumping out too many volts on the 5V rail - luckily this meant I could recover the recordings - I went down the road of replacing the entire board and swapped out the BIOS chip which matches the drive. Deep diving into it I learnt that the two TVS diodes for 5V and 12V work in conjunction with R64 and R67 (0 Ohms) so that the current shunts down to ground via the diodes and either blows the diode and/or the resistor to prevent damage to components further downstream - very sensible design IMO. Like you say - get the data off ASAP! Nice tip on using testdisk for MBR recovery :)

Good trouble shooting. Many times a a multi-meter is all that you need along with focused rational thinking. Reminds me of my days on a test bench in the Marines working on power supplies. Diodes are usually part of power supply problems ie, not turning on. You might want to get yourself a nice table mount vice grip to hold the things in place while soldering. Also, I would wick away that extra solder on the board before reinstalling. It can cause other problems.

One thing that might help you, instead of rebooting/replugging the disk to have the new partition scheme read, you might just use a 'partprobe' command which forces kernel to read the partition scheme from the disk again, eg. 'partprobe /dev/sdaX'

[@atmospheric5000]

Thanks a lot !! I was also facing the same problem, and solved it removing this diode too ! Lucky like you :))

[@TzOk]

In case of any doubts, this protection diode did its job, going to short circuit and saving the rest of the electronic components on the PCB. This is not a regular Zener diode, but the so-called TVS diode or a transil. In case of a voltage spike on input the short circuit to ground causing the faulty PSU to shut down. They can absorb pretty high energy.

[@seckinseckin3919]

yeah they say we can use it without TVS diode but without using it doesnt mean that we are open for new troubles ??

Interesting video. I have some old drives I have not used in a while, and I recently plugged them into a caddy, and they kept cutting the power to the caddy, I guess some short circuit protection. In another caddy I started to smell burning, and saw smoke after a few seconds. Both caddyies had decent power adaptors, and work with other drives. In fact, one was a brand new WD caddy I had after removing it's original drive. Of the 4 drives I tried 2 of them, with the same behaviour, and not wanting to mess up the caddies I stopped. I just checked, and the first 2 are shorting the right side sata pin onto pin 4 and 6 (not 5). I see the same thing on both drives. On drive 4 I think it's the same, and drive 3 seems OK, pin 1 not shorting to 4 and 6. I found a component, KVP 47A, and it seems to act like a diode, on drive 3, but not 1,2 and 4. I stumbled across your video by pure chance, in my KZbin recommendations, watched it casually, and when I saw, took a look at my drives. I might remove the KVP 47A component on one of the drives, just for kicks, since these are ancient 250GB SATA Maxtor drives I don't care about anyway, ideally I'd like to securely erase any remaining data prior to disposal, or letting someone else find a use for them.

[@waldevv]

I've seen zener diodes being used as voltage regulators before, particularly on a Commodore 64 for powering the cassette drive motors. The rail put out somewhere between 10-12V I believe but the tape drive needed something like 7 or 8 volts, can't remember as it was years ago but that's what the zener was rated at and since it starts conducting at that voltage it clamped the voltage down to the needed amount because everything "excess" got shorted to ground basically. Very effective however if it fails open circuit it unleashes the non regulated voltage to the motors, thankfully it survived when I accidentally did that. It was shorted initially which is why the tape drive wasn't spinning

It's generally unwise to write to the "patient drive" ... better would've been (even using free programs) to have used something like DD Recovery (and DO HAVE IT LOG, it can be very useful) ... create either an image on a drive (strengths and weaknesses to images) or clone the drive to a drive that at minimum has the number of sectors (in size) ≤ than the 'offset' to the last sector used ... ... then ONLY MAKE CHANGES TO THE DRIVE YOU'VE JUST CLONED; (especially if you're going to edit that partition in any way).

Interesting video. Considering the drive's diode was already toast, I hardly blame you for not wanting to use the original enclosure again. I'll just throw my two cents in... Having done a small amount of recovery from external enclosures that were sold with pre-installed HDDs I've seen some that use an intentional partition offset for the user's data. In those cases the SATA board in the enclosure is often designed to appear as two devices-- an HDD *and* a small CDROM drive or pre-loaded read only partition (inside the offset area) that contains the advertised and included software for backing up etc. You would see the drive using two drive letters, but each drive letter might show as different device types. If that's the case, then connecting it to any other SATA interface other than the one it came with will show the drive as uninitialized since the layout is intentionally non-standard. I'm guessing you might have unknowingly encountered one of those weird enclosures.

[@beardyface8492]

[@howard5992]

Was it necessary to use the dock ( at 10:19) or was that just convenient ? Also, assumed it would be necessary to replace the diode prior to powering it on again. Does the dock bypass the diode ?

[@Adamant_IT]

Dock was convenience. The drive will work without that diode, it just has less protection against electrical faults. Since we were just going for data recovery, it's no big deal to run it without the protection diode. If it had been an exotic or expensive drive, there might've been value in fitting a new diode, running diagnostics, and then using the drive again - but for a common drive, just replace the whole thing. Data's worth more than that.

Hot tip... The spring pins that go to the pads leading to the motor are a source of failure and frustration. Whenever I remove a board that has them I bend the pins upward just a little so they make better contact with the pads leading to the motor. If the pins don't put adequate pressure on those pads then the coils in the motor don't get sufficient current flowing for the controller to detect a properly functioning motor and so it spins up and down over and over.
