DATA RECOVERY

When data becomes inaccessible, every action matters.

Repeated repair attempts, a RAID rebuild or another write can reduce the chance of recovering information. The first step is preserving the useful state.

FIRST RESPONSE

Preserve before repairing.

  • Stop using the affected device where possible.
  • Do not initialize or format a volume whose condition is unclear.
  • Do not run repair, rebuild or recovery tools repeatedly.
  • Call UNITECH before additional writes occur.

    • For active data loss, calling is the most direct path.

BEFORE YOU ACT

Stop the escalation before more evidence is lost.

A repair attempt can change the state that diagnosis still needs to understand. Where the situation allows, preserve the original and record what happened before continuing.

  • Avoid writes that are not necessary for the business to keep operating immediately.
  • Keep the error messages, symptoms and actions already attempted.
  • A disk that makes an unusual noise or disappears from the system should be checked before any rebuild.

WHAT WE CAN ASSESS

From a deleted file to physically damaged storage.

Restoring from a backup makes a known copy available. Data recovery deals with media or a volume whose condition, files or structures are no longer reliable. The first diagnosis helps distinguish the two situations.

Logical recovery

Deleted files, lost partitions, corrupted volumes, backup images, VHD/VHDX/VMDK files and data accessible after encryption when clean sources exist.

Failed media

Disks, SSD, RAID, NAS or storage that require a careful approach and sometimes coordination with a physical-media specialist.

THE CASE

A method designed to avoid additional damage.

Preserve

Stop unnecessary writes and document symptoms, events and actions already attempted.

Diagnose

Assess the media, file system, RAID/NAS configuration or virtual-machine state.

Recover and verify

Work from a copy where possible, prioritize data and validate the files returned.

USEFUL INTAKE

What happened helps choose the next step.

Prepare the media type, affected system or application, priority data, last known good state and actions already attempted. We then explain limits, dependencies and the proposed path before going further.

Situations we can assess

  • deleted files or lost partitions;
  • corrupted file systems;
  • hard drives or SSDs that become unreadable;
  • RAID, NAS or volumes whose state is unclear;
  • damaged backup images;
  • VHD, VHDX, VMDK files or virtual machines that no longer boot;
  • recovery after encryption where clean sources exist;
  • Microsoft 365 data according to retention and available backups;

Recovery cannot be guaranteed before diagnosis.

The result depends on media condition, writes already made, available copies and data that can actually be recovered. For an active loss, data recovery is the right first path; a backup review can follow once sources are accessible again.

AFTER THE URGENT PART

A useful recovery starts with understanding why the situation happened.

Once the data is accessible again, you can separate what belongs to a recovery copy, what belongs to storage or infrastructure work and what needs an owner. This continuation does not assume a recurring contract; it helps choose the next decision.

Backup and recovery

Confirm what is covered, who receives failures and which restore has actually been tested.

Clarify who keeps track of access, storage, vendors and the next corrections.

Review managed and co-managed IT

Did a disk disappear or start making an unusual noise?

If you can do so without making the situation worse, power the device down and call before running more repair or rebuild tools.
