Eskişehir Data Recovery: A Short Distance from Central Anatolia to Ankara Hacettepe Teknokent

Eskişehir, in the northwest of Central Anatolia, is one of those rare cities where industry and the university are intertwined. From Tepebaşı to Odunpazarı, from the sprawling campus of Anadolu University to the hospitals of Eskişehir Osmangazi University (ESOGÜ), from the laboratories of Eskişehir Technical University (ETÜ) to the rail-system production lines of TÜLOMSAŞ and TÜVASAŞ, the data produced at every point forms the economic muscle of the city. The Eskişehir Air Supply and Maintenance Center and ASELSAN facilities on the defense-industry side, and meerschaum workshops and food factories on the traditional-production side, constantly leave new digital traces. In this data-intensive ecosystem, when disks fail, RAID arrays collapse or servers stop responding, a reliable nearby laboratory is needed in order to make the right decision.

DSET Data Recovery serves corporate and individual users in Eskişehir from its academically grounded laboratory based at Ankara Hacettepe Teknokent. We do not have a physical office in Eskişehir; instead, we have set up a secure delivery flow that reaches our Ankara base, 230 km away, by same-day shipping or courier. In this article we explain the effect of Eskişehir's geographic location on data recovery, the typical failure scenarios of the local sectors, the correct workflow within the KVKK and ISO/IEC 27037 framework, and how we produce service to Eskişehir from our Ankara Hacettepe Teknokent base.

Why Eskişehir Is a Strategic Location for Data Recovery

Eskişehir lies between Ankara and Istanbul, in the middle of the high-speed train line, at the intersection of the D200 and TEM connections. It is about 230 km from Ankara, roughly 2.5 hours by motorway and 1 hour 20 minutes by high-speed train. This proximity is a serious advantage for getting critical disks to an expert laboratory within hours.

The city's economic structure also makes this service need routine:

• Rail-system and railway manufacturing: The supply industry within the TÜLOMSAŞ and TÜVASAŞ ecosystem constantly produces CAD/CAM files, the logs of production-control panels and PLC histories. When the NVMe disk of an engineering workstation dies, the project's latest weekly drawings are at risk.
• Defense industry: The supplier chain of the Eskişehir Air Supply and Maintenance Center and the satellite firms around the ASELSAN facilities hold data that is technically critical even when it is not classified.
• University and research: Anadolu University's open-education infrastructure is the largest in Türkiye; at the ESOGÜ Faculty of Medicine Hospital, PACS image archives, and at ETÜ, aviation and engineering research data, are constantly in motion.
• Ceramics, meerschaum and food: The Logo, Mikro or ETA databases belonging to the accounting, pre-accounting and order software of family companies and SMEs often live on a single server.

This diversity means that the phrase "every failure is different" has a real counterpart in Eskişehir. A RAID 5 collapse at a TÜLOMSAŞ supplier and a corrupted database on the POS server of a restaurant in Odunpazarı are not solved by the same method. The right diagnosis requires the right team.

Our Ankara Base · Hacettepe Teknokent Foundation

DSET Data Recovery's laboratory is at the Ankara Hacettepe University Teknokent. This choice is deliberate. The Teknokent ecosystem gives us three things:

1. Academic proximity: Being on the same ground as Hacettepe's engineering faculties, computer-science department and hospital keeps us close both to a pool of interns and senior engineers and to specialized workloads such as medical imaging and research data.
2. Physical security: Teknokent gate control, card-based access, 24/7 security and closed-circuit recording systems strengthen the laboratory's perimeter security ring.
3. A dust-controlled environment: The clean benches used for HDD head replacement and platter-opening interventions operate in conditions close to ISO classification.

Every device arriving from Eskişehir is delivered to this infrastructure in Ankara. Rather than showing a fake Eskişehir address, we explain our real location and service flow transparently. This approach works against the most common trust problem in the data recovery sector in Türkiye: the customer knows where and to whom they are entrusting their device.

For a detailed process and laboratory structure, you can review our Ankara data recovery page.

Same-Day Delivery Flow from Eskişehir to Ankara

The short distance between the two cities leaves us comfortable on the logistics side. Our standard flow is as follows:

1. First contact. You reach us by phone, WhatsApp or the web form. In the first conversation we fill in a short form that asks about the failure symptoms, the device type (HDD, SSD, NVMe, RAID, NAS, server), the capacity and the data criticality. This form also becomes the first line of our case record.

2. Preparing the device. If the device is non-functional, do not move it and do not try turning it on and off. An HDD making a clicking noise wears down the data layer a little more with each startup. If an SSD has an electrical fault, it can further strain the thermal-control block. Prepare the device in air-cushioned packaging or in its original box, with an ESD-protective bag.

3. Logistics. We have two options:

• Courier: A motorized courier option that reaches Ankara from the central districts of Eskişehir (Tepebaşı, Odunpazarı) the same day or the next morning. We prefer this for sensitive RAID enclosures, servers and mini towers.
• Shipping: At hours when contracted couriers are not available, a package handed over in the morning reaches Ankara in the evening. This is sufficient for individual disks and laptops.

4. Delivery and the intake record. When the device reaches Ankara, we create an intake record with the serial number, photographs of physical damage and seal information. This record both protects your status as a data controller within the KVKK framework and ensures compliance with the "chain of custody" rule of ISO/IEC 27037. For details about the standard, you can see the ISO/IEC 27037 page.

5. Free diagnosis. Once your device is on the engineer's bench, a physical and logical preliminary diagnosis is performed. After the diagnosis we present you a written report: the type of failure, an estimate of recoverability, the time and the cost. Not a single byte is moved without your approval to proceed after the diagnosis.

6. Recovery and delivery. After approval, the recovery process begins. The cloning, head or controller replacement, firmware intervention, file-system repair and file-extraction steps vary according to the type of problem. The recovered data is transferred to an encrypted carrier disk and delivered to your Eskişehir address by courier or secure shipping.

Local Scenarios: The Cases We Most Frequently Encounter in Eskişehir

A RAID Collapse in the TÜLOMSAŞ/TÜVASAŞ Supplier Network

The rail-system supply industry mostly uses file servers running in a RAID 5 or RAID 6 configuration with between 4 and 8 disks. When one disk fails, the system continues in "degraded" mode; when a second disk drops out, the array goes down completely. One of the most critical mistakes is when the customer replaces the failed disk with a new one to start a rebuild, but because the array's parity is corrupted, the rebuild logically overwrites the entire array.

The correct move at this point is to clone all the disks in the array sector by sector first, then re-derive the array order and parity calculations on a virtual RAID. For the technical details of the RAID 5 scenario, you can read our RAID 5 recovery article.

PACS Images at ESOGÜ and Private Medical Centers

The ESOGÜ Faculty of Medicine Hospital, as a central hospital, operates integrated with PACS systems, but at the surrounding private imaging centers the DICOM archives are often kept on a single NAS. The failure of these NAS units to start after a power fluctuation or disk collapse directly cuts off access to patient data. Under the KVKK, health data is in the special-category personal-data class, and the data controller has an obligation to maintain access to this data. For details, you can refer to the KVKK official website.

Anadolu University Open Education Staff and Academic Data

The open-education infrastructure of Anadolu University, one of the most populous universities in Türkiye, means research data distributed across thousands of faculty members in addition to campus staff. Theses, assessment-and-evaluation files, Mendeley/Zotero libraries of articles, and video recordings prepared for exam systems often rest on a portable SSD or a laptop disk. A sudden failure on these devices can strike the academic calendar.

SME Accounting in Odunpazarı and Tepebaşı

From the boutique businesses on Odunpazarı's historic streets to the more modern business centers of Tepebaşı, Logo, Mikro, ETA or Netsis databases often live on a single SSD. The backup plan is limited to copying to an external disk once a month. When the SSD's controller dies, the last 3 weeks of invoices and current-account movements are at risk. The correct move in this scenario is to read the controller with PC-3000 or similar expert hardware without rewriting to the SSD.

Meerschaum Workshops and Food-Industry Production Data

In Eskişehir's meerschaum workshops and food factories, CCTV footage and production-line data are often collected on network-connected NVRs. The failure of NVR disks due to heat or humidity creates a problem both for security investigations and for production traceability.

Which Devices We Work On

• HDD: Mechanical disks, clicking noises, head failure, motor failure, platter damage.
• SSD and NVMe: Controller death, firmware corruption, NAND wear, unreadability after a sudden power loss.
• RAID arrays: RAID 0, 1, 5, 6, 10 configurations; multiple-disk failure, controller-card corruption, an incorrect rebuild.
• NAS and servers: Synology, QNAP, Buffalo, Asustor; Btrfs, ext4, XFS, ZFS file systems.
• Virtualization: VMware (VMDK), Hyper-V (VHD/VHDX), Proxmox (qcow2) image recovery.
• Databases: MSSQL, MySQL, MariaDB, PostgreSQL, Oracle, Logo, Mikro, ETA, Netsis database table / MDF / LDF recovery.
• Mobile and flash: USB sticks, SD cards, physically damaged phones (limited).

KVKK, ISO/IEC 27037 and Digital Forensics Compliance

Data recovery is not a purely technical matter. How the recovery process is carried out, whether it is recorded, and whether it is disclosed to third parties directly affect KVKK compliance. For our institutional customers we apply the following framework:

• KVKK: When a device comes to us, we take on the status of a data processor. For this reason we sign a written data-processing agreement with our customer, who is the data controller. Internally, the principle of minimum access (need-to-know) is applied. Review the KVKK website for the official legislation.
• ISO/IEC 27037: From the moment the device is received to the end of the recovery, the chain of custody is recorded. Which engineer touched which disk, at what time, with which tool, is written down. In a possible legal process, these records carry evidentiary value.
• USOM: In cyber-incident processes, especially when ransomware is suspected, we provide guidance on the USOM notification steps. Official portal: USOM.
• TÜBİTAK BİLGEM: For the cryptological and digital-forensics reference framework, we follow the work of TÜBİTAK BİLGEM; compliance with these standards is important especially for our defense-industry customers.

These frameworks form the fundamental difference between a data recoverer and the "I had a friend recover this device, he did it cheap" approach. The recovered data is not meaningful merely by having been recovered; how it was recovered, by whom it was extracted, and where it went are at least as critical as the recovery itself.

No Physical Office, but There Is Transparency

We want to emphasize this point once more: there is no physical DSET office in central Eskişehir. This is not a deficiency but a deliberate structural choice. The sector is full of operators who claim "we have a branch in every province" but actually move the data to other provinces in the background, break the chain of custody and sometimes hand the devices over to intermediary workshops. We reject this model.

One laboratory, one team, one chain of custody. A disk arriving from Eskişehir is opened at Ankara Hacettepe Teknokent, worked on there, and closed there. There are no vague points such as intermediaries, subcontractors or "our guy."

In this model, two clear advantages emerge for you:

1. Traceability: Who received your device, who delivered it, which engineer did what at which step, and with which software/hardware they worked are all in a single chain of records.
2. Consistency: There is no quality fluctuation tied to a difference between branches. Every case arriving from Eskişehir, Bursa or Istanbul goes through the same standard process. For Bursa details, you can find them on the Bursa data recovery page.

A Practical Roadmap for Eskişehir

Data loss often comes suddenly. Following the steps below while the disk is still working or has only just failed will significantly increase your chances of recovery:

• Shut the device down: In the event of symptoms such as clicking, a burning smell, or not appearing in the BIOS, do not keep the system on. Every second can enlarge the physical damage.
• Do not try to restart: Do not run the commands that the computer suggests during startup to "fix" the disk, or tools such as chkdsk or fsck. If a logical error mixes with a physical one, data can be permanently erased.
• Do not install data recovery software: Most of the software advertised online as "free data recovery" corrupts the state of the disk when it fails and steers you toward the paid version.
• If you have a backup, set it aside immediately: If there is a backup in the cloud or on an external disk, physically move that backup to a separate place before the recovery process begins. A double backup saves lives in ransomware scenarios.
• Call us: The first conversation is free. With a few questions over the phone, we suggest which path the device should take.

We have detailed the holistic framework of the process across Türkiye in our Data Recovery Guide 2026 article. There you will find what steps the route from Eskişehir to Ankara consists of and what to watch out for with each type of device.

Conclusion

Eskişehir is one of the most dynamic production and education centers of Central Anatolia. From rail-system factories to university campuses, from defense-industry suppliers to the boutique businesses in Odunpazarı, every sector carries its own data load. The dropping of this load is not just a technical disruption; it is a matter that directly affects commercial continuity, the education calendar, patient services and legal responsibilities.

DSET Data Recovery, with its laboratory based at Ankara Hacettepe Teknokent, combines the logistical advantage that high-speed-train and motorway proximity give to users in Eskişehir with academically grounded engineering quality. There are no fake branches, intermediary workshops or hidden subcontractors. There is a single-handed, transparent process compliant with KVKK, ISO/IEC 27037 and digital-forensics standards.

Whether you are calling from an office in Tepebaşı or Odunpazarı, from a laboratory at ESOGÜ, from a research unit at ETÜ, from a TÜLOMSAŞ or TÜVASAŞ supplier, or from a satellite-industry firm around Eskişehir Air Supply, the first conversation is the same: first we listen, then we guide you, and if necessary your device is on the road the same day.
