“Great communication with fast service, managed to retrieve all family photos and videos off a broken hard drive.”
“Viktor is an absolute legend! I hit the worst-case scenario with BitLocker locking me out completely a problem that could’ve cost thousands. Viktor stepped in and had it fixed in mere minutes. He didn’t just fix it; he guided me step‑by‑step exactly what to do. Thanks to his clear, expert directions, everything was sorted quickly and stress‑free. Massive thanks to Viktor.”
“This was my first time needing data recovery, and I’m so glad I went to Wildfire Data Recovery. After spilling coffee all over my laptop, I thought everything was lost—but Viktor was incredibly reassuring and got to work right away. He and his team are extremely fast, professional, and communicative throughout the process.”
“Excellent Data Recovery and re set up. Viktor goes above and beyond to explain everything regardless of how long it takes. After disasters through the years gone by with other so-called experts, it was stessfree and a relief to discover Wildfire. Excellent pricing and communication. ☆☆☆☆☆ Highly recommend 👌”
“Wildfire Data Recovery were fantastic to deal with from start to finish. Extremely responsive to any customer requests and we able to perform data recovery and phone repair where Samsung official repairer advised they would not likely be able to preserve the data. Very satisfied with Viktor and his team. Highly recommend 👌”
“Had a massive problem with my iPhone X as it suffered water damage. It was successfully recovered by Viktor. I did not back up this iPhone X which was a problem & bought a new iPhone 16 Pro Max as the other one was old. The data off the old iPhone was put into the Cloud & I downloaded from there onto the new iPhone which took about 5-6 hours to do from my end & it was easy to do. The phone now feels & resembles with the same look I have on my previous old iPhone. Many thanks to Viktor who provides a great service.”
“Absolutely outstanding service from Wildfire Data Recovery! We came to them with several locked Samsung and ZTE mobile phones that we could no longer access due to forgotten or lost PIN codes. From the beginning, their team was incredibly knowledgeable, transparent, and professional. They were able to bypass the lost PIN numbers and also recover them all for us, so we can now use our phones again.”
The question this case answers
Can a dropped hard drive be recovered?
Usually, yes, and this case is the typical shape of it. A drop damages the heads and often leaves a light contact mark on the platter; the data underneath is intact until the drive is run again on damaged heads. Recovery is a donor head swap in the clean-air hood, then imaging with the contact zone mapped and read last. The drives we cannot save are the ones that were powered on again and again after the fall, not the ones that fell.
The 20-second answer
If your hard drive is clicking after a drop, or a dropped external hard drive is no longer detected, switch it off and leave it off. The heads are damaged, the platters are almost certainly fine, and every power-on trades platter surface for nothing. Send it in on the free Express label; every dropped hard drive data recovery we take on starts with a free diagnostic that tells you the level and the fixed price before any bench work starts.
How it arrived
The drive was a WD_BLACK 4TB portable, the 2.5 inch USB kind that lives beside a laptop or a games console rather than inside a tower. It was plugged in, powered and busy when it was knocked off the desk. Picked up and reconnected, it spun up, clicked in a steady rhythm for a short while, went quiet, and never appeared in Windows again.
Healthy drivePower-on click, the spindle winding up, a tick as the heads load, then a steady hum. 6 seconds.
Failing driveThe same steady hum, with a hard click about twice a second that never settles. 20 seconds.
What healthy sounds likeA short rising whine as the platters come up to speed, a soft tick or two as the heads load, then an even hum. Seeks are faint, irregular ticks that stop when the work stops.What failing sounds likeThe hum is still there, so the motor is fine. The click is the heads sweeping out, missing the servo tracks and snapping back to park, over and over.If yours sounds like the second onePower it off. Every click is another pass over the platter with a head that has already failed.
The client did the two things we ask people to do: stopped trying, and rang us before opening anything. The drive arrived on our free Express label, packed flat with padding on every side, with a note listing the folders that mattered most. That list became the success test for the whole job.
What we found
No hard drive is designed to be dropped while its platters are spinning. The heads fly a few nanometres above the surface, and a fall from desk height slams them into it. The steady click afterwards is the head stack sweeping across the platter, failing to read the servo tracks that tell it where it is, parking, and trying again.
On the bench the USB board came off first. Its ROM read cleanly and the firmware modules on the platters were intact when we reached them later, so the electronics were not the fault. That mattered more than it sounds: on a WD portable drive the USB board also carries the encryption for the platters, so this board had to stay with this drive for the rest of the job.
Inside the clean-air hood the head stack showed contact damage on the sliders, and under magnification the platter carried a light contact mark near the outer edge where the heads had landed. No deep scoring. That inspection is the moment that decides a dropped drive: scoring through the coating is permanent, light marks are survivable.
What we did
The damaged head stack came out and a matching donor stack went in. The match is the whole job on a Western Digital drive: the donor has to come from the same family and firmware generation, with a preamp compatible with the drive's adaptive settings, or the new heads never find the tracks. WD Black data recovery, portable or desktop, turns on that match more than on anything else.
With the new heads fitted, the drive was not simply copied end to end. It went onto the PC-3000 with the contact zone mapped out first, the healthy areas read at full speed, and the marked zone left until last with short timeouts so the donor heads never dwelled over the damage. Everything readable went to healthy storage before a single file was opened.
1Healthy surface, full speed
2Around the mark, short timeouts
3Contact zone last: short passes, long rests
Read in this passAlready safe on healthy storageContact zone
The file system was rebuilt from the image, the client's nominated folders were located, and files were opened and checked one by one. The client saw the file list and the fixed quote before paying the success fee.
The hard part
The contact mark sat close to the outer tracks, which is where a file system keeps some of its most important structures. Reading those tracks with new heads is the riskiest minute of the job: push too hard and the donor heads pick up debris and fail. The answer was patience, not force. Short passes, long rests, and the damaged zone left until every other sector was safe.
The outcome
The nominated folders were recovered and verified. The drive was retired and the data returned on new media with tracked shipping.
- Nominated folders recovered and verified
- Files opened and checked one by one

The case drive, board off: tap a marker
This is the drive from this case with its USB board removed, photographed on our bench before it went into the clean-air hood. Four points explain why a dropped drive cannot be checked at home.
All four markers are explained below.
1Spindle motor hub
The motor under this hub spins the platter stack. After a drop we listen for three things: a spin-up that settles into a steady note, a spin that never reaches speed, or no spin at all. Each points to a different fault and a different first step on the bench, and none of them can be judged safely by plugging the drive in at home.
2Head-stack flex contacts
These gold pads are the only electrical path between the heads inside and the board outside. They carry the preamp signals, so a donor head stack must have a compatible preamp, and the pads must be spotless when the board goes back on. A drive clicking after a drop almost always has its fault on the far side of these pads.
3USB board and connector
On a WD portable drive the USB bridge and the drive controller share one board, and many models encrypt the platters through it. That is why this board, or its ROM contents, must stay with the drive, and why a board bought from another drive gives you nothing but an unreadable disk. In this case the board was healthy and stayed put.
4Sealed casting
Platters, heads, ramp and actuator all live under here in filtered air. Opening it anywhere except a clean-air hood adds dust that scores the platter on the first spin. This lid is the line between what a client can safely do and what has to happen in the laboratory.

Dropped hard drive checker
Three questions decide how a dropped drive is handled. Answer them for your drive and read the same verdict our intake desk would give you.
Without JavaScript, the short version: Running when it fell (or not sure) plus clicking now is a head failure with likely platter contact: Level 4, switch it off. Switched off when it fell and clicking now is a head failure with clean platters: Level 3. Beeping or buzzing after a fall is stiction: Level 3 to 4. Dead after a fall is usually a shifted board connector or a cracked board, often Level 3. Spinning and working after a fall: back it up immediately and retire the drive. Every extra power-on after the fall lowers the odds.

How hard did it hit? A fall impact estimator
Two things set the shock a drive takes: how far it fell and how quickly it stopped. Carpet stops a drive over a couple of centimetres; tile stops it in about a millimetre. Pick your fall and see the rough number.
Reference values in g, drop height divided by stopping distance:
| Height | Carpet | Timber | Tile |
|---|---|---|---|
| 40 cm | 16 g | 65 g | 270 g |
| 75 cm | 30 g | 125 g | 500 g |
| 110 cm | 45 g | 185 g | 730 g |
| 150 cm | 60 g | 250 g | 1,000 g |
Estimated peak shock
about 125g
Spinning when it hit: the heads landed on the platter
A hard knock. Flying heads are pushed into the platter at a fraction of this figure, so the surface matters less than the fact that the drive was running. Treat it as a head fault and keep it switched off.
Book the free diagnosticTextbook estimate only: drop height divided by stopping distance (carpet 25 mm, timber 6 mm, tile 1.5 mm). Real impacts vary with angle, enclosure and what the drive hit. It is here to show why the surface matters so much, not to grade your drive.
Behind the head swap
What a donor head swap actually needs
The donor is chosen before the client drive is opened, so the swap happens in one session under the hood. Four things have to line up.
- Same family and generation
Capacity alone means nothing. The donor comes from the same WD family and firmware generation, checked against the drive's own module data before anything is ordered.
- Compatible preamp and head count
The preamp on the head stack must talk to the drive's adaptives. A near miss reads nothing, or reads badly and scrubs the platter while it tries.
- Sealed until the hood
Donors stay in their anti-static bags until the moment of the swap. The hood is ISO Class 5 rated clean air; the bench outside it is not.
- One read, then retired
Donor heads are fitted to read the platters once and image them. Nobody puts a head-crashed drive back into service, and we do not offer it.

Honest numbers
How the odds stack up for this kind of fault
92% is our overall recovery rate across 15,000+ clients since 2016. For dropped hard drive data recovery the outlook swings on what was done after the fall, so here is how the scenarios compare on the bench.
| Scenario | Recovery outlook | What decides it | The odds-killer |
|---|---|---|---|
| Fell while off, clicks now, never re-tried | Head stack replaced, platters usually clean. | A second and third power-on attempt. | |
| Fell while running, clicks now, powered on onceThis case | How wide the contact mark is; most are narrow. | Leaving it running to see if it comes good. | |
| Fell while running, run for hours since | How much coating survived under the damaged heads. | Already done: the hours of running. | |
| Fell, now completely dead | Usually a connector or board fault, platters untouched. | A board swap without the ROM contents. | |
| Fell, spins and works | Whether you back it up before the weakened heads fail. | Trusting it for another year. |
Outlooks are qualitative. Per-scenario percentages are published only when our job records support them.
Sound familiar?
If your drive was dropped
Do this now
- Unplug it and leave it unplugged, even to check. Every spin on damaged heads scrapes the platter.
- Keep it flat and pack it with padding on all six sides. Keep the cable and enclosure with it.
- Write down the folders you need most; that list becomes the success test.
- Note the height of the fall, what it landed on and whether it was running. All three change how the drive is opened.
Do not do this
- Do not open it to look for damage. The lid is the line between safe and scored.
- Do not run recovery software, chkdsk or a format prompt on it.
- Do not try different cables, computers or enclosures. Each attempt is another spin.
- Do not freeze it, tap it or swap its circuit board.
Where this sits on the price ladder
What a job like this costs
Every hard drive job is classified Level 1 to Level 5 after the free diagnostic. Levels 1 and 2 are success fee only. Levels 3, 4 and 5 carry a fixed upfront fee agreed in writing before bench work starts.

Upfront fee + success fee
The current Level 4 guide is $725 + GST upfront and $700 + GST only upon success: $1,425 + GST ($1,567.50 including GST) in total if successful. This is the current guide, not a statement of the historical invoice for this case. Level 4 carries a fixed upfront fee for the donor parts and bench work, agreed in writing after the free diagnostic, then a success fee only when the files are recovered and verified. Assessment confirms the recovery level; the power state and symptom alone do not establish the required work.

How we verify a recovery
- The client nominates the folders that matter before bench work starts; that list is the success test, not a percentage.
- We image the drive first and work only on the image. The original is never used as a working disk.
- A file list and opened sample files are sent before the success fee is raised.
- Data is returned on new media with tracked shipping; the original drive is retired.
- We publish per-scenario percentages only when our job records support them. Where they do not, you get a qualitative outlook and the reasoning behind it.

Plain English
Ten terms from this case, explained
- Head crash
- Physical contact between a read/write head and the spinning platter. A drop while running is the most common cause. Light contact marks are survivable; deep scoring through the coating is not.
- Head stack (HSA)
- The arm assembly carrying every head in the drive, plus the preamp chip. A donor head swap replaces the whole stack, not one head.
- Preamp
- The amplifier chip on the head stack that conditions the tiny signals from the heads. A donor stack must carry a preamp compatible with the drive's own settings or it reads nothing.
- Servo tracks
- Position information written to the platters at the factory. The heads read it to know where they are; damaged heads that cannot read servo produce the classic click.
- Platter scoring
- A groove worn into the platter by damaged heads. It is the reason a dropped drive must not be powered on repeatedly: scoring grows with every spin.
- Stiction
- Heads stuck to the platter surface so the motor cannot turn. It causes the beep or buzz some dropped drives make instead of a click.
- ROM and adaptives
- Drive-specific calibration data stored on the circuit board. It is why a board from another drive does not work, and why WD portable boards, which also hold the encryption, must stay with their drive.
- Donor drive
- A matching drive used as a source of head stacks or boards. Matched by family, firmware generation and part number, never by capacity alone.
- PC-3000
- The ACE Lab hardware and software platform we image failing drives on. It lets us map damaged areas and control read timeouts so donor heads spend as little time over damage as possible.
- Clean-air hood
- The ISO Class 5 rated laminar-flow workstation where drives are opened. It keeps airborne particles off the platters during the head swap.
Straight answers
Questions a dropped hard drive raises
20 questions our intake desk hears about dropped drives, answered the way we answer them on the phone.
20 of 20 questions shown
No question matches that. Call 1300 806 557 and ask us directly.
The first hour
Can a dropped hard drive be recovered?
Usually, yes. A drop damages the heads and sometimes leaves a light contact mark on the platter, but the data underneath survives unless the drive keeps running on damaged heads. The job is a donor head swap in the clean-air hood, then imaging around any contact zone. The drives we lose are the ones that were powered on again and again after the fall, not the ones that simply fell.
What should I do if I dropped my external hard drive?
Unplug it and leave it unplugged. If it was running when it fell, assume the heads are damaged and do not plug it back in to check. Keep the cable and enclosure with it, pack it flat with padding on every side and send it in with our free Express label. Tell us the height of the fall, what it landed on and whether it was running; all three change how we open the drive.
Should I put a dropped hard drive in the freezer?
No. Freezing does nothing for damaged heads or a marked platter, and condensation forms on the platter surface the moment the drive warms up, which turns a survivable head swap into a corroded, scrubbed platter. The freezer stories online come from a different era of drives and a different fault. Leave it at room temperature, switched off.
Can I run data recovery software on a dropped hard drive?
Please do not. Software can only work through the drive's own heads, so every sector it tries to read is another pass of damaged heads over the platter, usually with long retries in exactly the damaged zone. Recovery software is for drives that are mechanically healthy and logically damaged. A dropped drive is the opposite.
My dropped WD portable drive asks me to format it. Should I?
No. The format prompt means the computer can see the drive but cannot read its file system, which after a drop usually means the heads are struggling on the tracks where the file system lives. Formatting would write over exactly that area. Unplug it, and if it was running when it fell, leave it unplugged until it reaches the bench.
What you are hearing
Why is my hard drive clicking after a drop?
The heads can no longer find the servo information that tells them where they are, so the drive sweeps the head stack across the platter, fails, parks and tries again. That sweep is the click. Every click is another pass of damaged heads over the surface, which is why a hard drive clicking after a drop must be switched off straight away and left off.
Why does my dropped hard drive beep or buzz instead of clicking?
A beep or buzz with no spin-up means the motor is trying to turn but cannot: either the heads have landed on the platter and are holding it, which is called stiction, or the bearing has seized from the shock. The data is normally untouched. The heads have to be lifted off the surface in the clean-air hood and replaced; tapping or shaking the drive to free them scratches the platter.
My dropped external hard drive spins and whirrs but does not show up. What does that mean?
The motor still runs but the heads are not finding their position, so the drive never reports ready to the computer. On a WD portable drive it can also mean the USB board took the knock. Both are diagnosable in minutes on the bench and both are recoverable in most cases, as long as the drive is not left running while you try different cables and computers.
My dropped hard drive is not detected. Is the data gone?
No. A dropped hard drive not detected by the computer usually has heads that can no longer read the drive's own firmware tracks, or a board or connector shifted by the impact. The platters are untouched either way. The data becomes unrecoverable only when a drive is run for long enough on damaged heads to scratch through the platter coating.
How do I know if my dropped hard drive has a head crash?
You cannot tell from outside, and there is no safe way to check at home. The signs that point to it are a drive that was spinning when it fell, a rhythmic click or a beep afterwards, and a computer that no longer detects it. The only real answer is the inspection in the clean-air hood, which is part of our free diagnostic.
Cost, time and odds
How much does dropped hard drive data recovery cost in Australia?
Assessment determines the recovery level. Our current Level 3 guide is $350 + GST upfront and $350 + GST upon success ($770 including GST in total). Level 4 is $725 + GST upfront and $700 + GST upon success ($1,567.50 including GST in total). From Level 3 up there is a fixed upfront fee for donor parts and bench work, agreed in writing after the free diagnostic, and the success fee is charged only when your files are recovered and verified. We never price a job over the phone; the free diagnostic sets the level, so the dropped hard drive recovery cost you are quoted is the real one.
How long does dropped hard drive recovery take?
Most head-swap jobs run on our standard turnaround, typically two to three weeks from arrival, with the donor search the variable part: a common WD family is usually on the shelf, a rarer one may need to be sourced. Critical and Emergency 24/7 options move the job to the front of the bench for a fixed fee. Imaging itself is paced by the platter condition; a drive with contact damage is imaged slowly on purpose.
Can data be recovered from a hard drive with scratched platters?
It depends on depth. Light contact marks that have not gone through the magnetic coating are survivable: we swap the heads and image around the mark, reading it last with short timeouts. Deep scoring that has cut through the coating is permanent for that area, and if it circles the tracks where the file system lives the outcome drops sharply. That inspection under magnification in the clean-air hood is the decision point for every dropped drive.
Is a dropped hard drive still recoverable if it was switched off when it fell?
Usually, and it is the best-case version of the fault. With the drive off, the heads were parked on their ramp away from the platter, so the surface is often clean. Clicking or silence afterwards means the shock shifted or damaged the head stack, or knocked a connector. The required work and recovery level are confirmed after assessment.
Can a dropped hard drive be repaired and used again?
No, and we do not offer it. A head swap is a recovery procedure, not a repair: the donor heads are fitted to read the platters once, the data is copied to new media, and the drive is retired. A drive that has had a head crash should never be trusted with data again, even if it appears to work.
Why can't I just swap the circuit board from another WD drive?
Because the board carries drive-specific adaptive data in its ROM, and on many WD portable drives the USB bridge on that board also encrypts everything written to the platters. A board from another drive has the wrong adaptives and the wrong key, so the drive either fails to start or reads as scrambled data. When a board really is the fault, we transfer or rebuild the ROM contents onto the donor board instead.
Sending it in
Can you recover a dropped laptop hard drive?
Yes. A laptop dropped while running puts its internal 2.5 inch drive through the same event as a portable drive, and the recovery is the same head swap. The extra step is that we remove the drive from the laptop first. If the laptop still powers up, do not keep using it: every boot on damaged heads costs platter surface.
How should I pack and post a dropped hard drive to you?
Request the free Express label, then pack the drive flat inside a box with padding on all six sides so it cannot move; an anti-static bag inside the padding is ideal. Include the cable and enclosure if it is a portable drive. Add a short note with what happened, whether it was running, and the folders you need most. Australia Post Express is tracked door to door.
Do you recover dropped hard drives from Sydney, Melbourne, Perth and regional Australia?
Yes. Our laboratory is in Brisbane and most dropped hard drive data recovery jobs arrive by post from across Australia on the free Express label. Brisbane-area clients can arrange collection. There is no client counter; the drive comes to the bench, the bench does not travel.
Can you recover a dropped drive that another company opened or could not recover?
Often, yes, but tell us before you send it. A drive that has been opened outside a clean-air hood, or that has had a failed head swap, is graded differently at diagnosis and the odds are lower because of the extra handling, not because of the original drop. Include any report the previous provider gave you; it saves bench time and money.
