External hard drive recovery is one of the most emotionally charged repairs we do. Someone's wedding photos, the entire family video archive, three years of business accounting records, a half-finished PhD thesis — these aren't replaceable purchases like a phone screen. We've handled hundreds of documented external storage recovery cases across Western Digital, Seagate, Toshiba and generic external HDDs, plus countless USB flash drives, SD cards and NAS volumes. Recent volume is high — WD Elements 2TB, WD My Passport, Seagate Expansion 2TB and Toshiba Canvio drives have all walked in within the last month.
What we recover from, and what the categories actually mean
Western Digital external HDDs — My Passport, Elements, My Book, My Cloud (network-attached), Easystore. The WD ecosystem dominates the Australian external-drive market and we see these weekly. WD's drives include hardware encryption via the USB-SATA bridge chip on most models, which has implications for recovery (see below).
Seagate external HDDs — Expansion (the budget line), Backup Plus, One Touch, Game Drive, IronWolf and ST3000 NAS drives. Seagate's failure patterns differ from WD — the bare drives are typically easier to recover at the physical level, but recent Backup Plus models also use hardware encryption that has to be worked around.
Toshiba Canvio — Basics, Advance, Slim. Generally simpler internal architecture than WD or Seagate (no hardware encryption on most models), which makes recovery cheaper when the failure is electronic. Mechanically these use the same head technology as Seagate (Toshiba and Seagate share manufacturing arrangements).
Portable SSDs — Samsung T5/T7/T9, SanDisk Extreme/Extreme Pro, WD My Passport SSD, Crucial X-series, Sabrent Rocket. SSD recovery is fundamentally different from HDD recovery — there are no moving parts, but the NAND flash management is proprietary, and a failed controller chip on a portable SSD often means the entire drive is unrecoverable at chip-off level (which is unfortunate but honest).
USB flash drives and SD/microSD cards — every brand and capacity. We see daily. The recovery approach depends on the failure mode (file-system, controller, physical damage).
NAS drives and arrays — Synology, QNAP, ASUSTOR, Buffalo, plus generic Linux mdadm software RAID. Single-drive failures, multi-drive cascades, controller-board failures.
How drives actually fail — by symptom
Different failure modes need different recovery approaches. The symptom usually tells us what's gone wrong before we even open the drive.
Clicking sound when plugged in. Almost always a head-stack failure — the read/write heads are physically damaged or stuck, and the drive's controller is trying repeatedly to recalibrate them. This needs clean-room work because the drive has to be opened to swap the head stack. Recovery success is high if the drive hasn't been power-cycled excessively; lower if it's been plugged in 50+ times trying to make it work.
Drive not detected at all (computer doesn't see anything when plugged in). Most common cause is the USB-to-SATA bridge chip inside the enclosure has failed — the bare drive is probably fine but the electronics that present it to your computer aren't working. On WD and recent Seagate drives with hardware encryption, the fix isn't just swapping the drive into a new enclosure; we have to physically transplant the original bridge chip's encryption parameters. Recovery cost is moderate.
Drive detected but shows as "not formatted" or "RAW". File-system level corruption — the drive electronics and platters are fine but the partition table or filesystem metadata has been corrupted, often after a power loss during write or an improper eject. Software-level recovery (we use the same tools as forensic data recovery: R-Studio Professional, X-Ways Forensics, dmde) usually rebuilds the file structure cleanly. High success rate, low cost.
Drive detected, files appear but you can't read them, or they're random/garbled. Either partial filesystem corruption (recoverable with the same software approach) or the drive has degraded sectors that are returning garbage data — needs imaging the drive sector-by-sector to a fresh drive while skipping the bad sectors, then file-system reconstruction from the image. Moderate success rate, moderate cost.
Drive dropped and now not working. Variable — sometimes the heads have parked safely and the drive is fine, sometimes the drop has dislodged something that's now scraping the platter. We diagnose without power-on first by listening to the drive when held by hand and checking for free spin of the platters before deciding whether power-on is safe.
Drive exposed to water or fire. Possible to recover but time-sensitive. Water-damaged drives need rinsing in distilled water and ultrasonic cleaning before they're dried out — if you let them dry naturally with salt or mineral residue, the contamination corrodes the platters. Fire-damaged drives depend on whether the heat reached the platter surface (recoverable if not) or just the case and electronics (also recoverable). Both are partner-lab clean-room jobs.

What we do in-house vs partner clean-room work
Being honest about where the work happens matters more here than in most repair categories, because the costs scale dramatically across these tiers.
In-house at our Erina workshop: file-system recovery (software-level), partition table reconstruction, bridge-chip transplantation for WD/Seagate encrypted enclosures, USB controller chip transplant on flash drives, firmware-level repair using PC-3000 hardware on supported drive families, sector-by-sector imaging of degrading drives, and the front-end diagnostic that determines whether the drive needs clean-room work in the first place. About 70% of the recoveries we do are completed entirely in our workshop.
Partner clean-room (specialist lab in Sydney): head-stack swaps, platter transplants, drives that need physical opening in a contamination-free environment. We send the drive there with documented chain-of-custody, the lab does the clean-room operation and ships the drive back to us, we then complete the file-system recovery from the now-readable drive at our workshop and deliver the data to the customer. This adds 5-10 business days to the timeline and adds the partner lab's fee to the cost.
We don't pretend to have a clean room we don't have. Some Australian competitors advertise clean-room services on their websites then sub it out — we're upfront about partner relationships because it's both ethical and because chain-of-custody documentation matters for legal cases.
The pricing reality
Data recovery costs vary more than any other repair category because the work varies more. Honest guide figures by category:
File-system level recovery (drive detected, files appear missing or "not formatted") — $200-380. Most jobs land here. High success rate. Standard "no data, no charge" applies if we can't recover meaningful data.
Bridge-chip transplant on WD/Seagate (drive not detected, but the bare HDD is okay) — $280-480. Moderate complexity, but matched donor enclosure has to be sourced.
USB stick / SD card software recovery — $180-300.
USB stick / SD card chip-off recovery (failed controller, requires NAND extraction) — $400-900. Specialist hardware required.
Drive imaging plus reconstruction (drive has bad sectors, needs sector-by-sector copy first) — $380-650.
Clean-room head-swap recovery — $800-1,800 depending on drive size and how much platter damage there is. Higher end for 4TB+ drives or where multiple platter surfaces are affected.
NAS / RAID recovery (single failed drive in healthy array) — $600-1,200. Includes imaging all member drives.
NAS / RAID recovery (multiple failed drives or controller failure) — $1,200-2,500+.
Forensic-grade recovery (legal case, chain-of-custody documented, forensic image preserved) — quoted per case, typically 30-50% premium over standard work. Legal-court-admissible reports included.
We always diagnose first and quote the actual figure before committing to the recovery. For most file-system level jobs we can give a quote on the phone after asking a few diagnostic questions; for physical-damage cases we need to see the drive before quoting accurately.
Outside the Central Coast? Post the drive in
Most of our data recovery work comes in by post — we receive failing drives from Sydney, Newcastle, Wollongong, the Hunter, Canberra and interstate every week. The workflow is straightforward: call or message on (02) 4311 6146 with a description of the failure (clicking? not detected? dropped?), we tell you what to expect cost-wise, you wrap the drive in bubble wrap (do NOT use rice or silica packets near it — moisture barriers go in their own bag), post tracked and insured for the data value (not just the drive replacement value — your data is what we're recovering), we diagnose on arrival and email you a firm quote before doing any chargeable work. Round-trip for in-house recoveries is usually 5-10 business days; clean-room work adds another 5-10 business days for the partner lab leg.
External drive clicking, dropped, or undetected?
WD, Seagate, Toshiba, portable SSDs, USB sticks, SD cards, NAS arrays. In-house file-system recovery plus partner clean-room access for head-swap jobs. No-data-no-charge on standard recoveries. Postal Australia-wide.

My external drive is clicking when I plug it in — is the data recoverable?
Almost always yes, but stop plugging it in. Clicking on a mechanical hard drive means the read/write head is failing to find the platter surface correctly — usually because the head itself is damaged or the head-stack assembly has crashed onto the platter. Every additional power-on of a clicking drive scratches the platter further and removes data permanently. The recovery process involves opening the drive in a clean room, replacing the head stack with a matched donor unit, then imaging the platter to a new drive on specialised hardware. Success rate is high for drives that are clicking but haven't been powered on repeatedly — significantly lower for drives that have been cycled 50+ times. Cost is typically $500-1,500 depending on the drive and how badly the platter is damaged.
My WD/Seagate drive isn't being detected at all — what's wrong?
Most common cause is a failed USB-to-SATA bridge inside the external enclosure, not a failed hard drive. On WD My Passport and Seagate Backup Plus models from the last decade, the drive electronics include a hardware encryption chip — even if you remove the bare drive from the enclosure and connect it directly via SATA, you won't see your data because it's encrypted by that specific bridge chip. The fix is bridge-chip transplantation (we solder the original chip onto a working replacement enclosure board), then imaging the drive normally. Cost is typically $250-500. Drives that fail this way and have been opened by the customer first are harder — sometimes the chip has been physically damaged during attempted DIY access.
What about USB flash drives and SD cards — can you recover those?
Yes, but the success rate depends entirely on what kind of failure it is. File-system corruption (drive shows as 'not formatted' or files appear deleted) has a high success rate using software-level recovery — typically $150-300, completed within 24-48 hours. Physical USB connector damage (snapped USB plug) needs solder work to replace the connector — around $180-280. Failed controller chip (USB stick suddenly not detected on any computer) needs chip-off NAND extraction and reassembly via specialised hardware — that's a specialist job, $400-900, with success rates lower than mechanical hard drive recovery because flash storage management is more proprietary.
Do you do clean-room work in-house?
No, and we're upfront about it. Genuine clean-room work — opening platter assemblies, head-stack swaps, platter transplants between donor drives — requires an ISO Class 5 or better cleanroom environment to avoid contaminating the platter surface, plus the matched donor inventory to source compatible parts. We have neither in-house. What we do is the front-end diagnostic and pre-clean-room work in our Erina workshop, and we partner with a specialist clean-room lab in Sydney for the platter-level operations. The drives are tracked, chain-of-custody documented (important for legal cases), and we manage the customer relationship through the whole process. This is a real cost — clean-room recoveries are $800-2,500 — but it's also the only way to get data back from a drive whose platters have crashed.
What's the "no data, no charge" policy?
For standard file-system level recoveries (the high-success-rate jobs that don't need a clean room — drives that mount but show "not formatted", deleted files, partition table loss), we work on a no-data-no-charge basis: if we can't recover meaningful data, you don't pay. This doesn't apply to clean-room work because we incur the partner lab's fee regardless of outcome, or to logic board work where we've already done significant labour to diagnose the failure. We're always upfront before starting work about which category your drive falls into and what the cost looks like in each scenario.
My drive was dropped — should I try plugging it in to check?
No. This is the most common way customers turn a recoverable drive into an unrecoverable one. A drop can dislodge the head-stack from its safe park position; the next power-on tries to spin up the platters with the heads still resting on them, which scratches the platter surface and destroys data in those scratched areas. Drives that have been dropped and then immediately powered off are usually recoverable. Drives that have been dropped and then power-cycled 20 times by an anxious customer trying to make them work are often beyond saving even with clean-room work. If the drive contains anything you genuinely don't want to lose, don't plug it in — bring it to us and let us diagnose it without further power-on.
Can you recover from a dead NAS or RAID array?
Yes, with the same caveat as single drives — every additional rebuild attempt on a degraded RAID adds risk. Synology, QNAP, ASUSTOR and generic Linux mdadm RAID arrays are recoverable at file level when one or more member drives have failed. The procedure: image every drive (failed and surviving) individually before doing anything else, then reconstruct the array virtually using the images. Costs scale with the number of drives in the array and which (if any) need clean-room work. A typical 4-bay Synology with one failed drive: $600-1,200. A 4-bay with two failed drives or a failed controller: $1,200-2,500+. We're upfront about likely cost ranges before starting. Critical: if your NAS is showing degraded but still online, take a backup or copy off the data NOW, before another drive fails — the cost difference between "NAS still works" and "NAS dead" recovery is large.
