seagate hard disk not detected. Does it spin? (what to do if you fried your drive by plugging in wrong power supply)
If your seagate hard disk not detected, first of all, power it on and listen to it with your ear right next to it. Does it spin?
If not, then it would be for one of the 3 reasons. Seized motor, unparked heads, or dead PCB (printed circuit board). There are also things like dead preamp, but on most brands of drives it would not prevent the spin up process.
I will begin with explaining what seized motor is. Seized motor on the hard drive is fairly common issue that you would find on Seagate hard drive generations 7200.8 7200.9 7200.10 7200.11 7200.12, as well as some hitachi/IBM 2.5” hard drives.
Seized motor would upon start up process with create a faint buzzing, and in some cases beeping sound. I would highly suggest that you seek professional help at this point. This is one of the most difficult tasks to perform on the hard drive, and without necessary equipment you will kill your hard drive in attempt to recover it.
However, these sounds are identical to the ones that the sound would make when heads are not parked properly. All modern hard drives offer touchless heads technology, meaning that the heads are never suppose to come in contact with the disk surface. In the past 3.5” hard drives used to park heads closer towards the center of the drive, and they would land right onto the platter surface that had air pockets to prevent sticking. That technology slowly started to get outdated and less reliable than touchless, so now hard drives park heads on the external parking ramp. Touchless technology offers more durability for the heads when the drive is off power. If it is dropped external parking ramp, that suspends heads in the air, is much better option than having heads sit on the actual disk surface. (this section is best to be read on our blog page here because I have pictures explaining the difference)
Unlike 2 issues above, dead PCB, will turn your drive completely silent. PCB failure would usually be caused by power surges, or plugging in a wrong external hard drive power supply. Dead PCB can be either replaced, or repaired on component level. Luckily, TVS Diodes would protect most hard drives PCBs for mishaps like this, so they need to be tested first. A transient-voltage-suppression (TVS) diode or thyrector is an electronic component used to protect electronics from voltage spikes induced on connected wires. Multimeter with continuity test option will quickly determine if you have a damaged diode or not. Ideally, if you detect the damaged diode it would need to be replaced with an identical one, but in our case since I just needed to recover the data from this external hard drive. After the failed diode was removed, client’s drive began to spin and get detected by our imaging equipment.

What if it does spin but isn't recognized?

[@MikeMedvedPlusFour]

Bro, this video saved me 400 bucks. Can't believe it was as simple as popping off a diode. Thanks!

[@hddrecoveryservices]

You are welcome

[@jamesrios520]

@@hddrecoveryservices I need help with this SAS Hitachi ultrastar hard drive. It beeps once when plugged in, but doesn't spin. I'm not sure if this is a diode with the s marking code. Here is a pic link... kzbin.info/www/bejne/oHmTeKeHmq-EnqM

[@Invisibleotis]

Thanks so much! I accidentally broke the connector to the diode, but my drive spun up enough to get the data off it. LIFE SAVER!

[@brianrichmond3777]

This video helped me to diagnose and get a damaged 1TB Seagate video hard drive (ST1000vm002) from a Rogers Nextbox 3 going again. The problem is exactly the same, a shorted diode (which did not test ok after removal). When I removed the diode the drive spun up and was recognized. I am surprised the drive board without that diode enables the drive to work. Can the drive be operated "as is" or should the diode be replaced?

[@vantival8069]

If it works again after removing the diode, could you use again your hard drive normally or do you have to backup it immediately?

[@millerprod]

Hello guy, I have a Seagate 4To who doesn't spin. I tried to remove the diode like you did but the disk still not spinning (I mesured 0.693 with multimeter). If I replace the entire PCB do you think it could works ? Thanks for your answer !

[@user-xm4sz8ck6l]

what software do you use for checking the heads and making the sector by sector copy?

[@GREGELZZ]

after removing diodes and having the drive power up would you advise against re-using the drive or would you allow clients to continue using the drive as is? or is best practice to backup the data and get a new drive?

[@peterthelesser6536]

Thank you so much. I removed the bad diode now hard drive spins! I am able to get data backed up. Can a diode be purchased and soldered in? Or the diode crapped because of some other issue?

[@nxu5107]

Hi, I liked your video. However I am left with the question, how can the circuit work without the diode? I am scared to apply power to the board without the diode as there is a chance it can fry the board. Can you please explain the role of the diode in this instance and how the board can work without it? Thanks.

[@naderzigby]

Thanks, this helped me retrieve data off a Sata 3.5 !

[@hddrecoveryservices]

[@ashleyannesley7568]

I'm having this exact same issue, removed the bad diode and tested continuity, all was well, but it's still silent. What do I do now?

[@AxelWerner]

whats that little extra pcb that interfaces usb to some ribbon cable that goes to the hard disks extra pins ?

[@rikkiturner]

I have the same Seagate HDD which was dropped from around 2ft a few days ago. Since then it will not work. I can hear that the disc is not spinning but there is also a beeping noise. Did your HDD also emit a beeping sound when plugged in? I'm just trying to determine if i have a PCB issue or internal issue(such as stiction/head damage/spindle problem etc) thanks

[@denibajric5084]

You are amazing you helped me soo much

[@sweetlou5902]

Thanks a million, the diodes on my 1TB barracuda were fine, but the pin contacts were dirty, cleaned them all and voila, now to save my files

[@MargotTaylorPhotographer]

I have 3 dead diodes 2 x 1ROZ and a small S41 on a seagate 4TB external drive that does not start up. the outside diode has power. I am a bit nervous about 3 removing them.

[@ypdriff2537]

Any idea about a repetitive humming noise coming from the drive and the platters don't seem to be spinning. Windows on detect 4GB... it's a 500 GB drive. Windows want's to format the 4GB (I didn't). FTK Imager won't mount the drive either. Drive failed during a power outage... suspecting a power surge. Checking what look like the diodes didn't find any shorts...

[@CraigMullins1]

How do I find out where to get a new pcb board and cost. Mine is dead. Big chip melted.

[@ArmanAm]

ST3000DM001 Have problems with Head 4... When imaging the drive I can see a pattern: where a batch of sectors wouldn't get read, then a long batch would get read, and then a small batch not read again etc - with equal intervals. I ran /7 -> X through serial and got resistance values for all heads. All heads reading around 300 (need to convert from HEX to Decimal) except head 04 (head 5) which reads 540. Unfortunately I do not have access to hardware recovery tools like PC-3000, MRT etc... I've disable re-trying reading in firmware through terminal and can now quickly image the drive with HDDSuperClone without getting stuck at dead head for too long. But have a cleanroom, so will attempt a head swap after 5 healthy platters get imaged. If headswap will not fix the problem - time to send to specialists with hardware recovery tools.

[@zmurillo]

Man i really aappreciate this video it saved my but how long can I use this driver without the diode

[@sarathkothalawala8071]

what was the software did you use to check the disk at the end.

Very interesting. Impressed with your knowledge and very professional. Shame we don't have people in the UK like yourself. Not only a very nice guy and knows what he's talking about but also whiling to share his experiences and knowledge here on KZbin. You sir have a new sub. An see myself going through your entire channel watching a lot. I've had a few experiences with bad drives and loosing data so will be interesting to watch your videos. I have a USB stick that says it read/write protected when it's not and has never been made protected. Just on day it decided to screw up and I lost so much. It's was only 8GB but I had 7 years of Xbox360 game save files and a backup of some important stuff. One question I'd like to ask. Without going into huge detail I have a custom water cooler very high preformance PC and I've seen some people have a clear top, see through lid or case cover on there HDD so you can see it all working etc. all my SSDs are on show and I'd love to do the same

[@hddrecoveryservices]

I see what you mean, I've seen those covers. Custom made out of plexy. At my old work we actually made one :). But once hard drive is opened it would be hard to keep it reliable, unless you run RAID1 in case it fails.

Thanks for your videos! Any idea what might be wrong if seagate 2TB works just fine when detected, but... it's not detected all that often lately?.. It spins just fine, no weird noises. No errors in any test, SMART is ok, disk isn't too old yet (the newest I have aside from its replacement). And somehow BIOS just says says it's not there after being stuck on motherboard loading screen for like 30 sec. Swapping to other SATA doesn't help, other hdds work fine in its place. Tried to clear its contacts like you showed in this video, doesn't seem to help (but I got it detected at least 2 times after that). There's no data to save left, just wondering if it's something that might save me 2TB of space being tossed to trash.

[@VornameNachname86]

yo, I received a factory new drive from Seagate and the motor doesn't spin up. It gets detected in the device manager, sometimes also in the disk management without any storage showing up for it. I actually ordered two units, both of them seem to be from the same charge, although the PCB of the defective drive looks a bit discolored. I tried that one first in my external drive enclosure and it didn't spin up, so I assumed my external enclosure was defective (many reported cases of not detecting drives with more than 2TB of storage). I dropped the other drive in there and it worked without an issue, so I guess my one of the new HDDs is simply defective. Do you have any thoughts on that?

Right now situation is: when connecting drive the computer I can hear that it starts spinning but after two-three seconds it just stops and nothing happens. Do you thing that this might be something with device pcb or power supply pcb? I know that this is only estimation and guessing without seeing device but I would like to know your opinion. I can upload video showing how it behaves if that helps... Alternatively, what would be estimated cost of recovering data from that drive?

[@computerssuck93]

Hey i just sent a drive to outsource datarecovery services, and i KNOW for a fact the data on it is still good. The problem it has is that it TRIES to spin up but cant complete it. So i logically figured its either gonna be the PCB or barely possible the Spindle having a problem. I was told 3 times that all it would need is the $60 pcb swap, then they call and say "nope only data recovery will work" But literally 30 mins before it just stopped spinning i WAS AT THE DAMN DESKTOP, the files are fine. And you seem like an upfront sorta dude, how much would it cost for a PCB swap, or in the worst case a Spindle swap, i really really dont have a lot of money, which is why when he quoted me $600 dollars for data recovery, i just thought "data recovery?? why it doesn't need data recovery, the problem is its not spinning up"

[@kb3at131]

So where do the probes for the multimeter go? One on each diode or one on each side of each diode?

[@hddrecoveryservices]

you need to test the diode. Negative probe goes on the cathode side of the diode, and the positive probe goes on the anode.

[@hectorpl2066]

Im sure this is a stupid question but I don't get something. You touch red and black probes together to demonstrate the sound. Isnt this exactly the same situation when the current goes through the diode? In other words if the current goes through the diode and we touch the red and black probes on both ends of the diode it should be exectly the same as if we just touch them together (without the diode in between) and the sound should occur?

[@j3ffn4v4rr0]

Not stupid, he was not clear about this: The basic function of a diode is to let current flow ONE way only....by "shorted" he means the diode lets current through both ways. The "arrow and a line" he mentioned is the symbol for a diode (can't type it here, just look it up and you'll see what I mean)...the arrow part of the symbol indicates which side is + and the "line" side of the symbol is the minus (negative) side. Current is supposed to flow from plus to minus, and if you test with the probes that way, you are supposed to get a sound...but if you switch the probes (put red on the minus side, and black on the plus side) and you still get a sound, the diode is no good.
