Hard Drive Recovery
Mechanical, electronic and logical failures need different approaches. AS assesses the drive first, images it where possible, and recovers from the image so the original is never put at further risk.

AS Data Recovery — Recover deleted, formatted and lost files and partitions from hard disks, SSDs, USB drives, memory cards, disk images and virtual disks.
When you need this
- Drive is not detected by the system or BIOS
- Clicking, grinding or repeated spin-up attempts
- Drive detected but files inaccessible or extremely slow
- Bad sectors, read errors or SMART warnings
- Accidental deletion or format on a working drive
- Drive dropped, water-damaged or power-surged
What we do
Diagnosis
We identify whether the failure is mechanical, electronic, firmware or logical, and whether the drive can be safely imaged as-is.
Controlled imaging
Failing drives are imaged with read-error handling and head-map control to capture as much data as possible before condition worsens.
Logical recovery
File systems (NTFS, exFAT, HFS+, APFS, ext) are reconstructed from the image to restore folder structures and file names where they survive.
Hardware-level work
Where a drive needs component or head work, it is handled in a controlled environment and only after the assessment confirms it is worthwhile.
Firmware-level repair
A drive's firmware lives partly in a reserved service area on the platters and partly in a small ROM on the PCB, storing its adaptive parameters, defect tables and the translator that maps logical to physical sectors. When that firmware is corrupted — a common cause of a drive that spins up normally but isn't detected, or hangs during initialisation — a straight PCB swap alone rarely fixes it, since the replacement board's ROM is calibrated to a different physical drive. We identify the exact firmware family and revision first, then work through the manufacturer's own diagnostic/terminal access (Seagate and Western Digital both expose serial terminal command sets for this; Samsung and Toshiba families use their own utilities) to repair or rebuild the affected module.
A firmware fault can live in the platters' reserved service area, the PCB's ROM, or both — which is why a straight board swap alone often isn't enough.
How it works
- Step 1
Consultation and scope
We establish what failed, what has been tried, and which data matters most. This shapes a targeted plan rather than a generic one.
- Step 2
Secure imaging and diagnosis
Where possible the source media is imaged before any work, so the original is never altered. Diagnosis then determines the safest recovery method.
- Step 3
Recovery
Data is extracted from the image or source using methods matched to the failure — logical, structural or hardware-level as required.
- Step 4
Verification
Recovered data is checked for integrity and completeness, and a file list is shared so you can confirm what matters is there.
- Step 5
Secure delivery
Verified data is returned through an agreed secure method, with guidance on validation before it goes back into production.
What affects the outcome
We have solved 656+ cases like these. Every case is assessed on its own condition, and we tell you exactly what is recoverable after a free assessment, before you pay anything.
- Physical condition of the media and the extent of any damage
- Whether the media has been written to, reformatted or re-initialised since the failure
- Encryption, corruption or partial overwriting of the data
- Availability of source data such as images, backups, logs or transaction records
- Attempts made before assessment (rebuilds, repair tools, repeated reboots)
AS Data Recovery
For healthy drives with deleted or formatted data, the software may recover what you need without a service engagement.
Frequently asked questions
Should I keep trying to power the drive on?
No. Each attempt on a mechanically failing drive can cause further platter damage. Power it off and contact us for an assessment.
Can data recovery software fix a clicking drive?
No. Clicking indicates a mechanical or firmware problem. Software can only help with logical issues on a drive that reads normally.
Do I need to send the drive to you?
For physical failures, yes. For logical failures on a readable drive, remote recovery may be possible after assessment.
What is "firmware-level" hard drive repair?
The firmware controls how a drive reports itself, maps sectors and applies its defect tables. When it's corrupted — often after a power surge or an interrupted firmware update — the drive can spin up but not be recognised by the system. Repair means entering the drive's diagnostic or terminal mode to repair or rebuild the affected firmware module, which is a different skill and toolset from the mechanical or logical-file-system work covered elsewhere on this page, and usually has to happen before the drive can be imaged at all.
Can a replacement PCB alone fix a firmware fault?
Rarely on its own. Most modern drives store adaptive calibration data (unique to that specific physical drive) on an onboard ROM chip, so a donor board only works once that ROM — or its data — is transferred across, or a board with a matching ROM revision is sourced. Swapping the board without addressing this usually leaves the drive undetected or unstable.
