Hard disk data loss is one of the most critical problems for businesses and individuals today.
When your important documents, photos or business data are lost, it is almost impossible to recover your data
without the right approach and professional equipment. As TeknikNokta,
with our 17 years of experience since 2007 and our ISO-certified laboratory,
we are one of Turkey's leading companies in hard disk data recovery.
Hard Disk Recovery: TeknikNokta's Power

Operations are performed in ISO 4 Class 100 Clean Room environment, in accordance with international standards.
We work with an average success rate of 87%; success may vary depending on the device and type of failure.
We know that no recovery operation is the same, regardless of the nature, severity or condition of the data loss.
Your dedicated data recovery specialist will work with you to determine the best course of action for your hard disk recovery operation.
Common Data Loss Scenarios
We provide solutions for common data losses such as deletion, formatting, electronic/mechanical failure, liquid/fire damage, virus and corruption.
Deletion and Format
Accidentally deleted files or accidentally formatted disks cause your data to become logically inaccessible.
In this case, data is usually present on the disk but cannot be read by the operating system.
Solution: Deleted or formatted data can be safely recovered with special data recovery software and techniques.
Electronic/Mechanical Failure
Electronic and mechanical failures resulting from hard disk drops, collisions, voltage fluctuations or motor failures are
one of the most common causes of data loss.
Solution: Physically damaged disks must be opened in an ISO 4 Class 100 Clean Room environment and repaired with professional equipment.
Liquid/Fire Damage
Water, liquid contact or fire damage can cause hard disks to be physically damaged and data to be lost.
In such damages, emergency intervention is critical.
Solution: Disk platters are cleaned with special techniques in a clean room environment and data is recovered with professional equipment.
Virus and Corruption
Malware, file system corruptions or bad sectors cause data to become logically inaccessible.
Solution: Corrupted file systems can be repaired with special software and techniques, and data can be safely recovered.
Mechanical Failures
If your hard drive is not working or making clicking and/or scratching sounds, it means you are experiencing a mechanical failure.
This may be due to a read head problem and/or motor failure.
Mechanical Failure Symptoms
Mechanical failures require a clean room (Clean Room) environment to open and examine the hard drive without causing further potential data loss.
If strange clicking or scratching sounds are coming from the hard disk, this is a sign that your drive may have experienced a read head problem and is not reading data correctly.
A read head problem can cause permanent, unrecoverable damage to your files if the drive continues to run.
Important: In case of mechanical failure, immediately shut down the device power and get professional help.
Contact our Data Recovery Experts to discuss the best recovery options for you.
If your hard drive is working but you cannot access some or all of your files, you are most likely experiencing a logical failure.
This may be due to a lost partition or accidental reformatting of the drive.
Common Logical Data Loss Problems
Common logical data loss problems include file deletion, corruption or file directory damage caused by a virus or malicious program.
Recovery Chance: In logical failures, data is usually present on the disk and can be recovered with special software.
Whether accidentally deleted or your files are lost, we still have a chance to recover the data.
Consult a TeknikNokta data recovery expert.

Useful Tips to Increase Data Recovery Success
Taking the right steps in case of data loss significantly increases recovery success.
By following the tips below, you can recover your data more safely.
Shut Down Device
Shut down the power of your computer or storage device to prevent further damage.
Recovery depends on the integrity of data and file structure, any operation on the device
may corrupt data or file structure.
Liquid Contact
DO NOT DRY. Corrosion begins with drying and increases data loss.
Place the hard drive in an airtight ziplock bag and send it to TeknikNokta office
as soon as possible for data recovery services.
Strange Noises
Shut down the device power. If strange clicking or scratching sounds are coming from your hard drive, this is
a sign that your drive may have experienced a read head problem and is not reading data correctly.
A read head problem can cause permanent, unrecoverable damage to your files if the drive continues to run.

Frequently Asked Questions
You can find answers to your questions about our hard disk data recovery service here.
How long does hard disk data recovery take?
Data recovery time varies depending on the type of damage and disk condition.
Simple logical errors can usually be resolved within 24-48 hours, while physically damaged disks
may take 3-7 days. We have fast intervention services for emergency situations.
How much does data recovery cost?
Pricing is determined according to the type of damage, disk capacity and recovery complexity.
Preliminary analysis is completely free and you will be given a firm price quote. If your data cannot be recovered
no fees will be charged. You pay only in case of successful recovery.
Can you recover data from all hard disk brands?
Yes, we provide data recovery services from Western Digital, Seagate, Samsung, Toshiba, Hitachi, Fujitsu and all other common hard disk
brands. Regardless of manufacturer or model, we have the necessary equipment
and knowledge base.
Is my data safe? Is privacy protected?
Absolutely. All your data is protected under the confidentiality agreement. We work safely in our ISO certified laboratory.
After the recovery process, your disks are securely destroyed
and your data is not shared with third parties.
What is your success rate?
We work with an average 87% success rate. Success rate may vary depending on the device and type of failure.
While this rate may be slightly lower in physical damages, we achieve higher success rates in logical errors.
After preliminary analysis, we provide you with detailed information about the success chance.
What happens if I try to open the hard disk myself?
Absolutely do not open it! Opening the hard disk in a normal environment causes dust and contaminants to
damage the disk platters. This can cause your data to be permanently lost.
Physically damaged disks must be opened in an ISO 4 Class 100 Clean Room environment.
Can you recover data from a formatted disk?
Yes, we can recover data from formatted disks. The formatting process usually only deletes the file
system, the data physically remains on the disk. With our special software, we can successfully recover
data from formatted disks. However, no new data should have been written to the disk after formatting.
RAID sistemlerden veri kurtarabilir misiniz?
Yes, we provide data recovery services from RAID 0, RAID 1, RAID 5, RAID 6 and other RAID configurations.
We also perform successful recovery operations in cases such as multiple disk failures, controller problems or incorrect configuration in RAID systems.
