How it's done

How We Perform Data Recovery

What our technicians do, what it requires, and how to tell you need it.

1 How It's Performed

For a recovery case, the first thing we do is stop using the affected drive entirely and work from a sector-by-sector image of it, so every recovery attempt happens on a copy — never the original — protecting whatever data is still intact from further damage during the process.

Typical time: 2–48 hours depending on damage severity

2 What This Requires

  • A sector-by-sector image/clone of the drive made before any recovery attempt — this is non-negotiable, since every recovery technique after this point works on the copy, not your only surviving copy of the data.
  • A clear diagnosis of logical vs. physical failure, since the two require entirely different tools and techniques.
  • For physically damaged drives: a controlled environment to avoid introducing further contamination while the drive is open.

3 When You Need This

  • Files or folders have disappeared, a partition shows as "RAW" or unformatted, or the drive was accidentally formatted.
  • The drive makes repetitive clicking or grinding noises — in this case, power it off immediately and stop using it rather than attempting more reads.
  • The drive isn't detected by the system at all, or is detected but shows 0 bytes of capacity.

About the Dell XPS

Best for: users wanting premium build quality and display in a Windows laptop

The Dell XPS is Dell's premium consumer laptop line — the flagship competing directly with the MacBook Pro, with a machined aluminum chassis, InfinityEdge display, and genuinely premium build quality.

Key features

  • Machined aluminum/carbon-fiber chassis — among the most rigid in Dell's lineup, but also among the most involved to open for repairs.
  • InfinityEdge display — very thin bezels, a genuine design standout, though panel replacement requires careful handling of the thin bezel assembly.
  • Often has soldered RAM on thinner configurations — check the specific model year before assuming an upgrade is possible.
  • Premium build commands a premium repair-parts price relative to Inspiron.

Dell XPS models we commonly repair

  • Dell XPS 13 9310
  • Dell XPS 13 9315
  • Dell XPS 13 Plus 9320
  • Dell XPS 15 9510
