Sakarya (Adapazari) Data Recovery: Professional Service from Eastern Marmara to Ankara Hacettepe Teknokent

Sakarya is an Eastern Marmara city where automotive manufacturing, railway engineering and agricultural trade are decisive on a Turkey-wide scale. The Adapazari-centered industrial basin, the service sector in Erenler and Serdivan, the forest products and food production in Hendek and Akyazi, the port logistics in Karasu, the tourism businesses in Sapanca and Geyve; all of them lean their daily operations on a large amount of digital data. The loss of this data, for a business, is not merely "the disappearance of a file," but the stopping of the production line, the breaking of the customer supply chain, and the suspension of legal obligations.

At DSET, our headquarters is in Ankara Hacettepe Teknokent. We do not have a physical office in Sakarya; however, we offer our corporate and individual customers based in Sakarya remote diagnostics, device transfer via insured courier, and professional data recovery in our clean room infrastructure in Ankara. This page has been prepared to transparently explain to those who want to reach us from Sakarya how the process works, which method is applied in which cases, and the legal framework.

Why Data Recovery from Sakarya to Ankara

Thanks to its proximity to Istanbul and Kocaeli, Sakarya forms the eastern end of Marmara's industrial corridor. The Toyota Motor Manufacturing Turkey (TOMSA) Arifiye factory is the locomotive of Sakarya's export economy, and dozens of supplier industry vendors, mold shops, plastic injection, cable harness and electronic control module manufacturers are positioned around it. The Adapazari Organized Industrial Zone (AOIZ), Hendek OIZ and Karasu OIZ; each hosts hundreds of firms producing ERP, MES, PLM and CAD data.

There are many small computer repair points in the Sakarya center that claim local data recovery, but because physically damaged disks require a class 100 clean room, NAND chip transplantation requires professional equipment such as PC-3000 Flash, and RAID rebuild operations demand laboratory-level infrastructure, for serious cases the device must be transported to our Hacettepe Teknokent laboratory in Ankara. This distance (about 360 km) is short enough to be delivered by insured courier usually the same day or the next morning, and it is a negligible cost next to the risk of permanent loss of valuable data through incorrect intervention.

Our preference for an Ankara-centered process also aligns with the Ankara-focused structuring of the national cybersecurity and digital forensics ecosystem of the Scientific and Technological Research Council of Turkey (TUBITAK BILGEM). You can reach the institution's work on its official site: bilgem.tubitak.gov.tr.

Sakarya's Industrial Structure and Data Loss Scenarios

The economic heart of Sakarya is automotive manufacturing. For the TOMSA factory and the supplier industry vendors in the Adapazari OIZ, a single hour of production stoppage creates hundreds of thousands of dollars of opportunity cost. The cases we encounter most frequently at these firms are as follows:

ERP/MES server RAID failures: On servers running on SAP, Logo, Netsis, IFS or Oracle EBS infrastructures, multiple disks in RAID 5 or RAID 10 arrays failing sequentially or simultaneously. Production orders, batch tracking records and quality control data are endangered. We detailed the technical particulars of the process and sample cases in our article RAID 5 Crashed, Recovery Process and Cost.

CAD/CAM workstation losses: Firmware-level failure of NVMe SSDs that host the CATIA, NX and SolidWorks files of mold engineers. Since redrawing a single mold project means weeks of engineering hours, in these cases the priority is flash translation layer recovery techniques.

Railway engineering data: Engineering firms working in Adapazari around the TUVASAS (Turkish Wagon Industry) ecosystem may keep wagon and locomotive design files in unbacked or inadequately backed environments. A disk or SSD failure puts the critical design library at risk.

Agriculture and food businesses: Disk failure of small-scale NAS devices that host accounting and stock management data at the hazelnut and corn processing facilities and dairy industry firms along the Hendek, Akyazi and Geyve line. Usually a RAID 1 or SHR configuration on 2 or 4-bay Synology, QNAP, or TerraMaster devices.

Tourism businesses: HDD failure on servers holding PMS (hotel management) and POS data for the boutique hotels and restaurant chains around Sapanca Lake. The loss of front-office accounting and reservation history directly affects period closing and VAT declaration.

Port and logistics: The disks of systems that digitally archive bills of lading, manifests and customs declaration records at the transport and customs brokerage firms around Karasu Port.

Lessons of the 1999 Marmara Earthquake and the Data Continuity Plan

Sakarya is also the province where the epicenter of the 17 August 1999 Marmara earthquake was located. Adapazari is one of the cities where the earthquake taught Turkey its most expensive lessons in terms of infrastructure, engineering and disaster management. While this experience has made firms operating in the region more sensitive about building reinforcement than other provinces, the same sensitivity has not settled into every organization regarding the digital business continuity plan (BCP) and disaster recovery (DR).

To Sakarya-based firms designing a data center or server room, we always make these three reminders:

1. The backup must not be kept in the same building. A backup in the same rack, same room, same building is destroyed together with the main data in an earthquake, flood or fire scenario. At least one copy must be kept geographically in a different location, preferably in a region with different fault line dynamics such as Ankara or Istanbul.
2. The 3-2-1 backup rule applies. Three copies, two different media, at least one copy offsite. For the offsite leg of this rule, Ankara-based corporate cloud services are a suitable choice for Sakarya organizations.
3. A backup whose restore has not been tested is not a backup. A full restore drill must be done every three months.

Due to the high groundwater level around Sapanca Lake, server rooms in basements in some parts of Sakarya are open to a routine water leak risk. Keeping the server room above the ground floor is a basic precaution against a flood scenario.

Process: How Does a Device Reach Us from Sakarya

The standard flow we apply for our Sakarya-based customers is as follows:

1. Preliminary Discussion and Remote Diagnostics (Same Day)

In the first phone or WhatsApp conversation, the brand, model, capacity, failure symptoms (is there noise, does the BIOS see it, is it logical or physical), backup status and the criticality level of the data are asked. This conversation takes an average of 15 minutes, and based on the preliminary diagnosis two possible paths are recommended: logical cases that can be solved with remote intervention or laboratory cases requiring physical intervention.

2. Device Transfer

In situations requiring physical intervention, shock-cushioned and insured transport is provided via a contracted courier. If the customer wishes, they can also bring the device themselves to our Ankara Hacettepe Teknokent office. The road distance from the Adapazari center to Ankara is about 360 km, and a device delivered in the morning usually reaches our laboratory the same day or the next morning.

3. Laboratory Diagnostics

In our class 100 clean room laboratory in Ankara, detailed diagnostics are performed with professional hardware such as PC-3000 (HDD/SSD/Flash versions), MRT Lab, and DeepSpar Disk Imager. At this stage the customer is presented with a written report and a fixed-price quote. A fixed price means there are no later surprises such as "this also came up, the price increased." We apply a no-data-no-fee policy.

4. Recovery Operation

In approved cases, head transplantation, PCB rework and firmware module repair for HDDs; NAND reading and flash translation layer reconstruction for SSDs; parameter detection and virtual array assembly for RAID are applied.

5. Verification and Delivery

The recovered data is listed for the customer, integrity tests are run on critical files, and it is delivered on new hardware. Encrypted delivery is provided if requested.

Legal Framework: KVKK and ISO/IEC 27037

The data recovery process, especially for corporate customers, is not only a technical operation but also a personal data processing activity. The data inside an ERP server or an accounting NAS contains customer identity information, personnel files, customer contact records, and financial information. For this reason every data recovery case must be assessed within the scope of the Personal Data Protection Law No. 6698 (KVKK).

The standards DSET applies in all Sakarya-originated cases:

• From the moment the device is received, a signed data processing agreement is made. The customer firm is positioned as the data controller and DSET as the data processor.
• During the recovery process, the working disks holding the data are protected with full disk encryption.
• After the case is closed and the customer has taken delivery, once the period specified in the contract (default 30 days) has elapsed, the working copies are securely erased in accordance with the NIST SP 800-88 standard.
• Throughout the process, the record and chain of custody is kept compliant with the ISO/IEC 27037 (Identification, collection, acquisition and preservation of digital evidence) standard.

The official texts of KVKK and the obligations of the data controller can be reached at kvkk.gov.tr. The ISO/IEC 27037 standard defines the processes of identification, collection, acquisition and preservation of digital evidence and is a critical reference in cases where digital forensics and corporate data recovery intersect.

Cyber Incidents: The Ransomware Scenario

Over the last three years, about a quarter of the cases we have received from industrial firms in Sakarya stem not from a classic hardware failure but from ransomware attacks. Attacks that begin on a Friday evening with employees connecting to the company VPN from their home computers with a weak password can move laterally through the network over the weekend and, by Monday morning, leave the entire file server, the ERP database and the backup disks encrypted.

The first steps to follow in these types of cases are as follows:

1. Instead of powering off the encrypted systems, isolate them from the network. Keeping them on preserves the possible encryption keys in RAM.
2. Follow the guides announced by the National Cyber Incident Response Center (USOM) and file an incident report: usom.gov.tr.
3. Before going down the path of paying ransom, consult an expert such as DSET. In some variants, decryption is possible with VSS shadow copies, file recovery tools, or known keys.
4. Check the status of the backups. If there is an offline backup (LTO tape, external offline disk), the priority is to restore it.

USOM is the official authority that coordinates cyber incidents nationwide and provides response recommendations by categorizing reported cases. In industry-dense provinces such as Sakarya, given the position of the automotive supplier industry within the OEM supply chain, it must not be forgotten that the cyber incidents experienced affect not only the firm but also its OEM partners.

Sakarya Surrounding Districts and the Relationship with Neighboring Provinces

Among the regions we serve from Sakarya, alongside the provincial center Adapazari, are the service sector in Erenler and Serdivan, the forest and food businesses in Hendek and Akyazi, the port logistics in Karasu, and the tourism and agriculture businesses in Sapanca and Geyve. At the same time, research data recovery requests from the academic units of Sakarya University and Sakarya University of Applied Sciences are also handled regularly.

Sakarya borders Kocaeli to the west and Duzce and Bolu provinces to the east. The process frequently used by our customers who also receive service from Bursa is explained on our city-based pages: our Bursa Data Recovery and Ankara Data Recovery pages look at the subject from different regional angles.

A systematic summary of the general data recovery methodology for all of Turkey can be found in our pillar article: 2026 Turkey Data Recovery Guide.

Our Pricing Approach

In the data recovery service, we are deliberately distant from the practice of "quoting a price over the phone." Because even the failure of two disks of the same model can involve different operational difficulty. Multiplying the price after a low figure stated over the phone, by saying "an additional fault came up" in the lab, is an approach frequently encountered in the sector that victimizes the customer.

DSET's pricing principles:

• Preliminary diagnosis and remote discussion are free.
• After laboratory diagnostics, a case-specific fixed-price quote is given.
• Operation does not begin without the quote being approved.
• If data is not recovered, no fee is charged.
• The entire process is carried out with a contract and invoice.

The real cost of your case can only be determined after diagnosis.

Contact and Conclusion

Our corporate and individual customers based in Sakarya win the process by taking the most critical step correctly in data losses: instead of tampering with the device, powering it off and getting an expert opinion. Restart attempts, "let me look with a tool on my own" approaches, and amateur extraction interventions lower the chance of recovery with every passing minute.
