Data recovery services in Sheffield

Professional data recovery for laptops, desktop computers, SSDs, hard drives and external storage devices

Losing important data can be one of the most stressful experiences for both home users and businesses. Whether it’s family photographs, business documents, customer databases, emails, accounting records or years of personal files, the thought of losing them permanently can be devastating.

At Byte IT Computers LTD, I provide professional data recovery services for customers throughout Sheffield and the surrounding areas. Every recovery case is approached carefully because no two storage devices fail in exactly the same way.

Data may be recoverable from:

Laptop hard drives
Desktop hard drives
Solid-state drives (SSDs)
External hard drives
USB flash drives
Memory cards
Corrupted Windows installations
Accidentally formatted drives
Deleted partitions
Damaged file systems
Liquid-damaged laptops
Computers that no longer power on

The success of any recovery depends on several factors, including the type of storage device, the cause of the failure and, most importantly, what happened after the problem first appeared.

Stop using the device immediately

If your data is important, stop using the device as soon as you notice a problem.

This is by far the most important advice anyone can give you.

Many customers unintentionally reduce the chances of recovering their files because they continue trying to “see if it still works”. Every time a failing drive is powered on, Windows attempts repairs, or new files are written to the storage device, the likelihood of successful recovery may decrease.

If your computer or storage device has failed, do not:

Continue turning it on to see whether it starts.
Restart it repeatedly.
Attempt to reinstall Windows.
Format the drive.
Initialise a storage device that Windows reports as “not initialised”.
Run CHKDSK or other disk repair tools.
Install or use data recovery software.
Save new files onto the affected drive.
Continue copying files from an unstable drive.

If the storage device is physically failing, every additional read or write operation places further stress on damaged components.

If important data has been deleted, every new file written to the drive increases the risk of permanently overwriting the deleted information.

In most cases, the first recovery attempt offers the best chance of success, which is why it is important that the first attempt is carried out correctly.

Why DIY data recovery attempts make things worse

The internet is full of free recovery programs promising to recover deleted files in just a few clicks.

While these tools can sometimes help with very simple deletion cases, they are not suitable for every situation.

If the storage device has developed physical faults, electrical faults, bad sectors, liquid damage or intermittent connection problems, recovery software can make the situation considerably worse.

Many recovery programs continuously scan the entire storage device. On a failing drive, this places the hardware under sustained load for long periods.

This may result in:

Additional bad sectors developing
More unreadable areas appearing
Further mechanical wear
Complete drive failure
Corruption of the file system
Previously recoverable files becoming permanently inaccessible

Windows repair utilities such as CHKDSK are designed to make a drive usable again, not to preserve damaged data.

They may alter directory structures, remove damaged file references or relocate information while attempting repairs. Once these changes have been made, recovering the original data may become significantly more difficult.

Similarly, reinstalling Windows, performing a factory reset or formatting the drive can overwrite file system structures that professional recovery methods rely upon.

If the information stored on the device is genuinely important, attempting DIY recovery before obtaining professional advice is rarely the safest option.

Warning signs of storage failure

Storage devices rarely fail without warning.

If you notice any of the following symptoms, stop using the device and arrange an assessment as soon as possible.

Common warning signs include:

Clicking, grinding or beeping noises from a hard drive
Windows taking an unusually long time to start
Files disappearing unexpectedly
Documents that suddenly become corrupted
Frequent freezing while opening files
Repeated Blue Screen errors
“No boot device” messages
Windows asking to format the drive
Extremely slow file transfers
Folders that refuse to open
SMART warnings
Drives repeatedly disconnecting and reconnecting
An SSD or hard drive no longer appearing in Windows
Burning smells
Signs of corrosion
A laptop that stopped working after liquid damage

Many customers continue using the computer despite these warning signs because it still appears to function.

Unfortunately, storage devices often deteriorate gradually before failing completely. Continuing to use them during this stage can significantly reduce the amount of recoverable data.

Liquid damage and data loss

Liquid damage is one of the most common causes of catastrophic data loss in modern laptops.

Many people assume that spilling a drink onto a keyboard only affects the keys. In reality, liquids often travel much further inside the device than most people realise.

Depending on the type of liquid and the way it entered the laptop, it may reach:

The motherboard
SSD or hard drive connectors
Storage controllers
Power management circuits
Data buses
Internal flex cables
Charging circuitry

Liquids containing sugar, salt, milk, coffee or alcohol are particularly destructive because they leave conductive and corrosive residues behind.

Even if the laptop appears to work normally after the spill, corrosion often continues developing long after the liquid has dried.

This corrosion can eventually destroy electrical connections that were initially unaffected.

For this reason, many laptops arrive weeks after a spill, by which point the customer can no longer access their files.

Never power on a liquid-damaged device

If liquid has entered your laptop, every attempt to switch it on increases the risk of permanent damage.

Electricity flowing through contaminated circuitry can create short circuits that damage components which may previously have survived the spill.

It is not uncommon for a laptop that initially required only cleaning to suffer complete motherboard failure because it continued to be powered on after the incident.

In some cases, the SSD or hard drive itself also becomes damaged, making data recovery considerably more difficult.

If the information stored on the laptop is valuable, preserving the storage device should always take priority over attempting to make the laptop work again.

What to do after a liquid spill

If you spill liquid onto your laptop:

Disconnect the charger immediately.
Switch the laptop off.
Do not attempt to turn it back on.
Do not continue pressing the power button.
Do not connect it to charge.
Do not use a hairdryer, heat gun or radiator.
Do not place it in rice.
Arrange a professional inspection as soon as possible.

Contrary to popular belief, placing electronics in rice does not remove corrosion or clean contaminated circuit boards.

Rice cannot remove sugars, salts or other residues left behind by spilled drinks. While it may absorb a small amount of moisture, it does nothing to prevent ongoing corrosion inside the laptop.

Professional cleaning involves completely dismantling the device, inspecting affected areas under magnification and removing contamination using appropriate electronic cleaning methods.

The sooner this is carried out, the greater the likelihood of preventing permanent damage.

When data is more valuable than the device

Many customers understandably focus on repairing the laptop itself.

However, if the information stored on the device is more valuable than the hardware, it is important to make this clear from the beginning.

Attempting repairs simply to make the laptop operational again may place unnecessary stress on a failing storage device.

Where the primary objective is recovering irreplaceable files, the recovery strategy should instead focus on preserving the storage media and extracting the data safely before considering any hardware repairs.

In many cases, a laptop can be replaced.

Family photographs, business accounts, legal documents and years of personal work often cannot.

Data recovery evaluation

Every data recovery case begins with a professional evaluation.

Before any recovery work is carried out, I first need to determine what has caused the failure, whether the storage device can be accessed safely and which recovery method is most appropriate.

This process takes time, specialist equipment and technical experience. For that reason, every recovery begins with a non-refundable evaluation fee of £60.

The evaluation fee covers the inspection and assessment only. It is separate from the cost of the data recovery itself.

During the evaluation, I may:

Inspect the storage device and its physical condition.
Determine whether the drive is detected correctly.
Check for signs of mechanical, electrical or liquid damage.
Assess the condition of the file system.
Identify bad sectors or communication errors.
Determine whether specialist equipment or laboratory work may be required.
Estimate the likelihood of recovering the requested data.
Provide a quotation for the recovery work.

Once the evaluation has been completed, I will explain my findings in plain English, discuss the available options and provide an estimated cost before any chargeable recovery work begins.

The £60 evaluation fee remains payable regardless of the outcome, including where:

No recoverable data is found.
The storage device has failed beyond recovery.
Specialist laboratory work is recommended.
The customer decides not to proceed.
The estimated recovery cost exceeds the customer’s budget.
Recovery is only partially possible.

Data recovery prices

The cost of data recovery varies significantly depending on the condition of the storage device and the complexity of the recovery.

Unlike standard computer repairs, there is no fixed price that applies to every situation. Recovering a few accidentally deleted files from a healthy drive is very different from recovering business data from a liquid-damaged laptop or a mechanically failed hard drive.

As a general guide, data recovery services start from £100 and may exceed £1,000 in particularly complex cases.

The following prices are based primarily on the amount of data successfully recovered.

Amount of recovered data	Estimated recovery fee
Up to 50GB	£100
More than 50GB up to 100GB	£240
More than 100GB up to 200GB	£360
More than 200GB up to 300GB	£460
More than 300GB up to 400GB	£560
More than 400GB up to 500GB	£660
More than 500GB up to 1TB	£760
More than 1TB up to 2TB	£1,000
More than 2TB	Quotation required

Please note:

The £60 evaluation fee is separate from the recovery fee.
These prices are intended as a guide only.
The final quotation will be provided after the initial evaluation has been completed.

Why recovery prices vary

Many customers ask why data recovery cannot simply be charged according to the size of the drive.

The reason is straightforward: two drives of exactly the same capacity can require vastly different amounts of work.

For example, recovering 30GB of family photographs from a healthy SSD that was accidentally formatted may take considerably less time than recovering 10GB of accounting data from a liquid-damaged laptop with severe motherboard failure.

The final price may depend on several factors, including:

The type of storage device.
Whether the storage device is physically damaged.
Whether the damage is logical or electrical.
Whether the device has suffered liquid damage.
The number of unreadable sectors.
Whether the drive disconnects during imaging.
The amount of corruption present.
Whether previous recovery attempts have been made.
Whether specialist software or hardware is required.
Whether donor components are needed.
Whether specialist laboratory work is necessary.
The amount of data requested by the customer.
The amount of data successfully recovered.
The total time required to complete the recovery safely.

Every recovery case is unique, which is why a proper evaluation is always carried out before providing a quotation.

Logical and physical data recovery

Data loss generally falls into two main categories: logical failures and physical failures.

Understanding the difference helps explain why some recoveries are relatively straightforward while others are significantly more complex.

Logical data recovery

Logical recovery is carried out when the storage device itself is still functioning, but the information stored on it can no longer be accessed normally.

This may happen because of:

Accidental deletion.
Formatting.
Corrupted partitions.
Damaged file systems.
Windows installation failures.
Failed updates.
Malware infections.
Corrupted boot records.
Lost or damaged user profiles.

In these situations, the storage hardware itself may still be healthy.

Where possible, the first step is to create a complete sector-by-sector image of the storage device. Working from an image rather than the original drive helps reduce the risk of further damage and preserves the original media should additional recovery attempts become necessary.

Physical or electrical data recovery

Physical recovery is considerably more complex because the storage hardware itself has been damaged.

Examples include:

Clicking hard drives.
Grinding or scraping noises.
Failed read/write heads.
Seized spindle motors.
Electrical damage.
Burnt controller boards.
Failed SSD controllers.
Damaged NAND memory.
Broken connectors.
Severe liquid damage.
Fire or impact damage.

These cases often require specialist equipment and, in some situations, controlled laboratory conditions.

If external laboratory services are required, this will always be discussed with you before any additional costs are incurred.

The data recovery process

Recovering data safely is rarely as simple as connecting a drive to another computer.

Every case follows a structured process designed to maximise the chances of success while minimising further damage.

Step 1 – Initial inspection

The storage device is visually inspected to identify signs of physical damage, corrosion, overheating, impact damage or previous repair attempts.

At this stage, it is extremely helpful if you can explain:

What happened before the problem occurred.
Whether the device was dropped.
Whether any liquid was involved.
Whether unusual noises were heard.
Whether Windows displayed any warning messages.
Whether any recovery software has already been used.
Whether another repair shop has already worked on the device.
Which files are most important to recover.

This information often provides valuable clues that help determine the safest recovery method.

Step 2 – Technical assessment

The storage device is then examined using specialist diagnostic equipment.

Depending on the condition of the device, this may include:

Checking whether the drive communicates correctly.
Reading SMART information where available.
Assessing the health of the storage media.
Identifying unstable or unreadable sectors.
Checking for controller faults.
Assessing file system integrity.
Identifying signs of encryption.

At this stage, I determine whether the storage device is safe to image or whether alternative recovery methods are required.

Step 3 – Recovery quotation

Once the evaluation has been completed, you will receive a clear explanation of:

The likely cause of the failure.
Whether recovery appears possible.
The recommended recovery method.
Any significant risks.
An estimated turnaround time.
The expected recovery cost.

No chargeable recovery work will normally proceed without your approval.

Step 4 – Controlled imaging

Where possible, I create a complete sector-by-sector image of the storage device.

Working from an image rather than repeatedly accessing the original drive significantly reduces the risk of further deterioration.

This also preserves the original storage device should additional recovery attempts become necessary later.

Step 5 – File reconstruction

Once a stable image has been created, specialised recovery software is used to rebuild:

Partitions.
Folder structures.
File allocation tables.
Deleted files.
Damaged directories.
Corrupted metadata.

Where possible, the original folder structure and filenames are preserved.

However, where file system damage is extensive, recovered files may instead need to be organised by file type.

Step 6 – Verification

Before returning the recovered data, I verify as much of the recovery as reasonably possible.

This may include checking:

Documents.
Photographs.
Videos.
PDF files.
Email archives.
Databases.
Folder structures.
File sizes.

Please note that large recoveries may contain thousands or even millions of individual files. It is therefore not always possible to manually verify every single file.

Step 7 – Returning your data

Recovered data is normally copied to a separate storage device supplied by the customer.

If required, I can also supply a new external SSD or hard drive at additional cost.

The destination device must have sufficient free capacity to hold all recovered files.

Once the recovered data has been safely transferred and verified, I will advise you to make at least two independent backups as soon as possible.

No storage device lasts forever, and a proper backup strategy is the best protection against future data loss.

What can and cannot be guaranteed

Data recovery can never be guaranteed.

Every storage device fails differently, and the success of any recovery depends on numerous factors, including the type of failure, the condition of the storage media and the actions taken before the device was submitted for assessment.

While every reasonable effort will be made to recover your data, it is important to understand that no reputable data recovery company can guarantee a successful outcome.

Even where recovery is successful:

Some files may be corrupted or incomplete.
Original folder structures may not be fully recoverable.
File names may be missing or changed.
Photographs or videos may only partially open.
Databases or email archives may require additional repair.
Previously overwritten files may be permanently lost.

Likewise, a storage device being recognised by Windows does not necessarily mean the data can be recovered, and a drive that is no longer detected may still contain recoverable information using specialist recovery methods.

Deleted and overwritten data

Many people believe that deleting a file immediately removes it from the storage device.

In reality, this is usually not the case.

When a file is deleted, the operating system normally marks the space occupied by that file as available for future use. The original data often remains on the storage device until new information is written over it.

This means deleted files may still be recoverable, provided the storage space has not already been reused.

Recovery is generally more successful where:

The device was switched off soon after the deletion.
No new files were copied to the drive.
Windows was not reinstalled.
The drive was not formatted.
Recovery software was not repeatedly used.
The storage device remained physically healthy.

Once deleted data has been overwritten by new information, it is usually impossible to recover.

For this reason, continuing to use a computer after accidental deletion significantly reduces the chances of a successful recovery.

SSDs and TRIM

Solid-state drives (SSDs) behave differently from traditional hard drives.

To maintain performance, most modern SSDs use a feature known as TRIM.

When a file is deleted, TRIM informs the SSD that the associated memory blocks are no longer required. The SSD may then erase those blocks in the background, allowing them to be reused more efficiently.

While this improves performance and extends the lifespan of the SSD, it can also make deleted files permanently unrecoverable.

For this reason, the recovery window for deleted files on SSDs is often much shorter than on traditional hard drives.

If you have accidentally deleted important data from an SSD, stop using the device immediately and seek professional advice without delay.

Encrypted storage devices

Many modern computers automatically encrypt their storage to protect personal information.

Examples include:

Microsoft BitLocker
Windows Device Encryption
Third-party encryption software

Encryption provides excellent protection against unauthorised access, but it also means that recovering data without the correct credentials may be impossible.

Depending on the device, recovery may require:

Your Windows password.
Your BitLocker recovery key.
Your Microsoft account details.
Other encryption credentials associated with the device.

Byte IT Computers LTD cannot bypass properly implemented encryption or recover encrypted files where the necessary credentials are unavailable.

Customers remain responsible for providing any passwords or recovery keys required to access their own data.

Previous repair or recovery attempts

If someone has already attempted to repair your computer or recover your data, please let me know before any work begins.

This includes:

Running recovery software.
Using CHKDSK or other repair utilities.
Formatting the storage device.
Reinstalling Windows.
Performing a factory reset.
Repartitioning the drive.
Opening the storage device.
Replacing electronic components.
Attempting motherboard repairs.
Cleaning liquid damage.
Work carried out by another repair company.

This information is important because previous repair attempts may alter the condition of the storage device and influence the recovery strategy.

Providing a complete history allows the safest and most appropriate recovery method to be selected.

Frequently asked questions

Can you guarantee that my data will be recovered?

No. Unfortunately, no professional data recovery company can guarantee a successful recovery. Every case is different, and the outcome depends on the condition of the storage device and the type of damage.

Should I keep trying to turn the device on?

No.

Repeatedly powering on a failing computer or storage device can make the problem significantly worse and may permanently reduce the chances of recovering your data.

Should I try recovery software first?

Not if the storage device is making unusual noises, disconnecting intermittently, responding very slowly, has suffered liquid damage or shows signs of physical failure.

Recovery software places additional strain on the storage device and may worsen the damage.

Can deleted files be recovered?

Sometimes.

If the deleted data has not yet been overwritten, recovery may be possible. The sooner you stop using the device, the greater the likelihood of success.

Can you recover data from an SSD?

In many cases, yes.

However, SSD recovery is often more complex than traditional hard drives due to features such as TRIM, encryption and modern controller technologies.

Can you recover data after Windows has been reinstalled?

Possibly.

However, reinstalling Windows may overwrite part of the original data, reducing the likelihood of a complete recovery.

If this has happened, stop using the computer immediately and arrange an assessment.

Can you recover data from a liquid-damaged laptop?

Often, yes.

Even if the laptop itself cannot be repaired economically, the storage device or its contents may still be recoverable.

However, every additional attempt to power on a liquid-damaged device increases the risk of permanent damage.

Is the £60 evaluation fee refundable?

No.

The evaluation fee covers the time, specialist equipment and technical work required to assess the condition of the storage device.

It remains payable regardless of whether data can be recovered or whether you choose to proceed with the recovery.

How long does data recovery take?

Every case is different.

Simple logical recoveries may be completed within a relatively short period, while physically damaged or unstable storage devices may require significantly longer.

A more accurate estimate will be provided after the initial evaluation.

Need professional data recovery?

If your files have become inaccessible, every minute counts.

Continuing to use a failing storage device may significantly reduce the chances of recovering your data.

Whether you’ve accidentally deleted important files, your laptop has suffered liquid damage, your hard drive has failed or your SSD is no longer recognised, professional assessment at the earliest opportunity offers the best chance of a successful recovery.
