Data recovery is the process of rescuing inaccessible, lost, corrupted, or formatted data from storage media when it cannot be accessed through normal means. It is an important tool for retrieving lost personal and business data. There are many potential causes of data loss, including hardware failure, accidental deletion, file corruption, ransomware attacks, natural disasters, and human error. When important data is lost or inaccessible, data recovery services provide the ability to recover and restore that information.
Data recovery is often critical for both individual consumers and businesses. Personal photos, videos, documents, and other files may hold sentimental value or record important life events. Businesses rely on data for daily operations, compliance requirements, analytics, and institutional knowledge. The loss of mission-critical business data can be catastrophic. By using data recovery methods, organizations and professionals can help mitigate the risks and costs associated with data loss.
Causes of Data Loss
There are several common causes that can lead to data loss from an external hard drive, including:
Hardware failure – Hard drives can experience mechanical failures or electronic circuitry failures that make data inaccessible. This is one of the most common reasons for data loss.
Accidental deletion – Users may accidentally delete files or format drives, erasing data. This human error is a top cause of data loss.
Corruption – Software errors, viruses, or physical damage to the drive can corrupt data so it is unreadable. File corruption is another major cause of data loss.
Theft – External hard drives that are lost or stolen result in data loss. This is why encryption is recommended for portable drives.
Water damage – Liquids spilled on a hard drive can short circuit components and make data recovery impossible. Keeping drives away from liquids reduces this risk.
Other causes include malware attacks, natural disasters, fire or smoke damage, and manufacturing defects with the drive hardware. Insufficient backup is also a common factor leading to data loss when hardware fails.
Data Recovery Process
The data recovery process typically involves several key steps:
Evaluation: The first step is for a data recovery specialist to evaluate the damaged drive to determine the cause and extent of data loss. They will assess the likelihood of recovering the data successfully.
Cloning: To avoid any further damage to the original drive, the specialist will create a clone or image of the drive to work from. This protects the integrity of the data.
Repair File System: If the file system is corrupted, the specialist will attempt to repair it to make the files and folders accessible again.
Extract Data: With the filesystem repaired, the specialist can now extract the lost or inaccessible data from the clone and copy it to another storage medium.

Factors Affecting Cost
There are several key factors that influence the cost of recovering data from an external hard drive:
Type of storage device – External hard drives can use different technologies like HDD (hard disk drives), SSD (solid state drives), or flash drives. HDD recovery is typically cheaper than SSD or flash drive recovery. SSDs and flash drives lack moving parts so the approach to recover data is more complex [1].
Cause of failure – Logical failures like accidental deletion or formatting are often easier and cheaper to recover from than physical damage to the device. Physical damage usually requires disassembly and specialist tools [2].
Amount of data – The amount of lost data being recovered impacts cost. Recovering a few gigabytes is cheaper than recovering multiple terabytes. Some providers charge per GB recovered [3].
Technology used – The tools and techniques involved play a role too. Software recovery tools are cheaper than hardware recovery methods like swapping chips. Clean room facilities add more costs [2].
So in summary, expect to pay more for SSD recovery, physical damage, large data amounts, and hardware-based techniques when recovering files from an external drive.

Average Cost Ranges
The cost of data recovery can vary significantly depending on the type of storage device and the extent of the damage or failure. Here are some typical price ranges:
Hard disk drives (HDD)
Logical failure recovery: $300 – $1000
Physical failure recovery: $800 – $2500
Solid state drives (SSD)
Logical failure recovery: $500 – $1500
Physical failure recovery: $1000 – $3000
In general, logical failures are less expensive to recover from than physical failures. Logical failures occur when the file system or partition tables get corrupted, but there is no physical damage to the disk itself. Physical failures arise from hardware malfunctions or physical damage to the device. SSDs tend to have higher recovery costs than HDDs.
The cost also depends on the storage capacity of the device. Recovering data from higher capacity drives naturally costs more than lower capacity ones. Lastly, the complexity and amount of manual work involved impacts the price. Advanced techniques like a clean room recovery from severely damaged drives costs the most.

When DIY May Work
In some straightforward cases of data loss, you may be able to recover data yourself using DIY software or methods. This is most likely to be successful if the data loss was caused by accidental deletion, a corrupted drive, or minor logical damage.
For example, if you accidentally deleted important files and realized shortly afterwards, free recovery software like Recuva may be able to restore them. Or, if the external hard drive’s file system became corrupted, running chkdsk or a repair utility could fix the issue.
Using recovery software can sometimes retrieve raw data from a drive with damaged partitions or a reformatted drive. But more complex issues like physical damage require sending the drive to a professional recovery service.
Overall, DIY recovery methods are worth trying first for basic data loss issues before resorting to paid recovery services. But they are not a substitute for professional help when hardware damage or complex logical issues are present (Sources: https://www.ontrack.com/en-gb/blog/lost-data-on-your-phone-heres-what-to-do-next, https://www.quora.com/Can-we-use-our-mobile-phones-as-external-storage-devices-for-our-computers-similar-to-how-we-use-USB-flash-drives)
Choosing a Service Provider
When selecting a data recovery service, it is important to research their reputation, capabilities, and security measures. Here are some tips for choosing a reliable provider:
Check reviews and testimonials. A reputable company will have positive feedback about their data recovery success rates, customer service, and transparency about pricing. Look for detailed reviews rather than brief anonymous ones.
Ask about their experience and capabilities. An established company that specializes in data recovery will have more knowledge and resources to handle complex cases involving different storage devices and types of data loss. Ask specific questions about their experience with your type of issue.
Inquire about security protocols. Responsible data recovery services will explain how they protect and secure clients’ personal data throughout the process. This includes data encryption, restricting employee access, and secure disposal of storage devices after recovery.
Get cost estimates in writing. Beware of businesses that won’t provide written estimates or guarantees about costs. Reputable providers will assess the work required and give you a written estimate of the recovery costs.
Consider tools and techniques. Ask how they recover data and what tools they use. Cutting-edge techniques like clean room recovery indicate greater capabilities to salvage data.
Check credentials and certifications. Licenses, accreditations like ISO certifications, and partnerships with major hard drive manufacturers demonstrate compliance with high standards.
Understand the process. Professional data recovery firms will be able to explain their recovery process in detail, giving you confidence in their approach.
Looking at a service provider’s reputation, transparency, capabilities, and security protocols can help give you assurance you are choosing a reliable data recovery partner. Proceed with caution if a provider does not readily offer information about their practices, experience, and policies.
Preventing Data Loss
There are several ways to help prevent data loss from occurring in the first place:
– Perform regular backups of your data to an external hard drive or cloud storage. Backups provide a copy of your data that can be restored in case of data loss. Experts recommend the 3-2-1 backup rule – 3 copies of your data, 2 local copies and 1 offsite/cloud copy.
– Use a RAID array which spreads data across multiple hard drives. This provides redundancy so if one drive fails, data can be reconstructed from the remaining drives. RAID 1, 5, 6 and 10 are common configurations.
– Use an uninterruptible power supply (UPS) to prevent data loss from sudden power outages. The UPS provides backup power to safely shut down systems.
– Store data on enterprise-class hard drives designed for 24/7 operation and RAID environments. Consumer hard drives are not built for constant activity.
– Maintain proper temperature and humidity in server rooms according to hardware specifications. Environmental factors can lead to premature disk failures.
– Install surge protectors, fire suppressors, and water sensors to protect against power surges, fire, flood and water damage.
– Follow cybersecurity best practices like firewalls, malware protection and access controls to prevent against data loss from security breaches.
Conclusion
Data loss can happen to anyone and the costs to recover that data can vary widely based on the type of storage device, the amount of data, and the techniques required. While averages costs range from $300 for a basic external hard drive recovery to over $5000 for a damaged SSD or RAID array, many factors influence the final price.
Prevention is always preferable to recovery. Be proactive by consistently backing up your data and choosing storage solutions wisely based on your needs. But even with the best preparations, disasters happen. In those cases, weigh the value of your data against the cost of professional recovery services. For irreplaceable or mission-critical information, the price may be well worth it.
With proper diligence, you can limit your risk and make smart decisions if data recovery becomes necessary. Just remember – your data is an asset. Plan now to protect it.
