Our advice to avoid making
data loss worse
Stay calm, and above all, don’t take any risks!
Hardware faults
Switch off the device immediately, especially if you hear unusual noises.
Don’t force the drive with tools that don’t handle bad sectors — this could scratch the platters.
Never open the drive outside a cleanroom. This will leave traces, and labs charge extra for the time needed to clean the platters.
Pack your hard drive carefully when shipping it
Non-hardware faults
You can no longer access your data.
Above all, stop writing anything to the drive: don’t install software, or worse, copy data onto the drive that suffered the loss.
If you need to keep working on the computer, clone it onto an identical drive and work from an external enclosure instead.
Water and fire damage
Cleaning is delicate! Do not dry the drives.
For submerged hard drives: it’s best to leave them in water to prevent corrosion — ideally in a sealed plastic container filled with distilled water.
Stay calm — we’ve already seen dozens of these 🙂
Frequently asked questions
Databases sit at the heart of modern information systems. They hold customer data, financial transactions, HR information, business applications and the ERP systems businesses depend on to operate. Corruption or unavailability can cause major service outages and significant financial consequences.
With more than 20 years of experience, Chronodisk helps businesses recover critical databases, whatever system they use.
Causes of database data loss
Businesses generally use databases to store and organise the strategic information their operations depend on: customer data, financial transactions, HR information, business applications, ERP systems or e-commerce platforms. Losing this data can cause immediate service disruption, affect the whole organisation and lead to significant financial consequences.
Several causes can lead to a failure resulting in data loss or database unavailability. Database management systems (DBMS) are exposed to numerous risks, including:
- Corrupted MDF, NDF or LDF files in Microsoft SQL Server.
- Configuration or migration errors.
- Damage to data files or transaction logs.
- Accidentally deleted tables or records.
- Server, RAID or storage infrastructure failures.
- Ransomware attacks or malicious infections.
- Power outages or hardware problems.
- Disasters (fires, floods, power surges, lightning).
- Accidentally overwriting a usable backup.
- Human error during maintenance operations.
- And more.
In short, database recovery covers several categories of incidents that can affect SQL environments and their associated infrastructure, namely:
- Logical faults.
- Hardware faults.
- Application incidents.
- Cyberattacks.
- Human error.
Recovering your data from databases
With more than 20 years of experience in data recovery, we put our expertise to work for businesses facing incidents affecting their databases. Whether it’s a Microsoft SQL Server, Oracle, MySQL, PostgreSQL or MongoDB database, our teams can restore critical data that has become inaccessible, corrupted or deleted.
We know that the information held in a database is often essential to your business: customer data, orders, financial transactions, business applications, ERP systems or e-commerce platforms. That’s why we apply strict recovery procedures to preserve the confidentiality and integrity of your data.
Our engineers have solid experience and use advanced methods to respond quickly, even in the most complex environments. To do this, they rely on a laboratory equipped with the technology needed to analyse, rebuild and restore damaged databases.
Our database recovery services are tailored to each case and cover the leading database management systems on the market:
- Microsoft SQL Server
- MySQL
- MariaDB
- PostgreSQL
- Oracle Database
- MongoDB
- IBM Db2
- SQLite
- SAP HANA
- Redis
The process for recovering your data with Chronodisk is simple. At the first sign of a problem, get in touch with our teams. Our customer service is available 6 days a week, and our crisis unit can be mobilised quickly in an emergency.
Once we have your files, backups or storage media, we carry out a technical analysis to identify the nature of the incident: corrupted MDF files, accidental deletion, server failure, a damaged transaction log or a ransomware attack.
Depending on the type of incident and your operational constraints, our engineers can work:
- In our laboratory: this approach is preferred for complex cases requiring in-depth analysis of data files, backups and transaction logs.
- Remotely or on-site: where the environment allows, our teams can work directly on your infrastructure to reduce downtime and restore your data as quickly as possible.
Chronodisk’s advice
Incidents affecting a database can be made worse by inappropriate handling. A corrupted SQL database isn’t necessarily lost for good. If something goes wrong, we recommend that you:
- Do not restart the server repeatedly.
- Do not reset SQL services.
- Do not overwrite existing backups.
- Do not run repair tools you’re not familiar with.
- Keep the transaction logs.
- Keep a copy of the MDF, NDF, LDF or equivalent files.
- Avoid any further writes to the affected server.
By keeping your environment in its original state, you maximise your chances of recovering your critical data.
