Our advice on avoiding
further data loss
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 laboratories charge extra to clean the platters.
Pack your hard drive carefully when shipping it
Non-hardware faults
You can no longer access your data.
Above all, don’t write anything else 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 to an identical drive and then work from an external rack.
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 handled dozens of these 🙂
Frequently asked questions
Known as Network Attached Storage, a NAS server is an excellent system used to store files on a central volume and then share them among network users. Easy to manage, it’s reliable and offers excellent performance. That doesn’t stop it from failing, though. There are always handling errors and failure risks that can lead to the loss of important information. Because we know this kind of situation can happen at any time, and that it can be damaging for you and your business, we offer our NAS server data recovery services at Chronodisk!
Causes of data loss on a NAS server
Generally, servers are used by businesses to centralise a large volume of data essential to their operations. Losing it can paralyse an entire area of activity, limit the company’s ability to function, and even lead to significant financial losses.
Several causes can lead to a failure and the loss of important files. The storage devices used in this type of system are generally subject to the same problems as hard drives, namely:
- Drive failures caused by a partition or formatting issue
- RAID configuration errors
- File system corruption
- Volumes corrupted, deleted or damaged due to human error or viruses
- Power supply failures or motherboard issues
- Disasters (flooding, fire, lightning)
- Accidental overwriting of files
- Adding hard drives incompatible with the RAID
- Etc.
In short, NAS server data recovery covers the same types of faults encountered on physical storage media, namely:
- Logical faults
- Mechanical faults
- Electronic faults

Depending on the type of fault and your needs, our technicians can work:
- In our laboratory: most of the time, working in our cleanroom is the most recommended approach. It has all the tools we need to diagnose, analyse and recover your inaccessible information.
- On site: we can also travel to the location of the fault to carry out the NAS server data recovery process.
Chronodisk’s advice
NAS malfunctions can be fixed and lost information can be recovered, provided you take the right steps. If you notice a problem, we recommend that you:
- Avoid working on the system once you detect a problem
- Avoid resetting the system’s devices or hard drive
- Avoid any system reconfiguration
- Do not format the failed RAID
- Do not reset the failed system
- Do not install a new hard drive after a failure
By keeping all devices and storage media exactly as they are, you reduce the risk of permanent loss and give the recovery process on your NAS server the best chance of success.
