Why We Don't Advertise a Data Recovery "Success Rate"

Written and maintained by the Desert Data Recovery lab team. · Updated July 14, 2026

It would be easy to add a big "98% success rate" to our homepage. It would probably even help us win business. We don't, because we can't stand behind a number like that honestly — and neither, if you look closely, can the labs that advertise one. Here's what those figures actually mean, what they hide, and what we think you should judge a recovery lab on instead.

Nobody audits these numbers

Start with the simple part: there is no independent body that verifies data recovery success rates. No regulator collects them, no standard defines them, and no auditor checks them. Every percentage you see on a recovery company's website is a number that company typed onto its own page, measuring itself, by its own definition, with nobody checking the math.

That doesn't automatically make every such number dishonest — but it does make it unverifiable, and an unverifiable claim is worth exactly as much as the trust you already have in whoever made it. A statistic you can't check isn't evidence; it's marketing.

"Success" can mean almost anything

Even setting aside honesty, the word "success" has no fixed meaning in recovery, so a lab can define it in whatever way flatters the number:

• Does recovering one file count? If a lab pulls back a handful of files from a drive but not the folder you actually cared about, is that a success or a failure? Depending on the definition, both count toward a rosy percentage.
• What's in the denominator? A rate is a fraction. If a lab turns away the hard cases at the door — or excludes them from the count — its "success rate" on the cases it chose to take will naturally look excellent, while telling you nothing about whether it would have helped you.
• Which cases are counted at all? Physically destroyed media, overwritten data, and key-lost encrypted drives can quietly drop out of the sample, leaving only the winnable cases behind.

Two labs could both do identical work and advertise wildly different "success rates" purely based on how they define the word. The number tells you about their marketing, not their bench.

An average across every failure type is meaningless for your case

Here's the deeper problem, even with a perfectly honest, perfectly audited number: it would still be useless to you. Data recovery isn't one thing. It spans everything from an accidentally deleted file that takes minutes, to a firmware fault, to a head crash that needs cleanroom work, to a drive whose platters are scored past reading. Success is close to certain at one end and genuinely impossible at the other.

Blending all of that into a single percentage produces a number that describes none of the individual cases. Knowing that a lab recovers "95% of cases" tells you nothing about whether your clicking, dropped, or water-damaged drive is in the 95% or the 5%. The only figure that matters is the one for your specific device — and that can't be known from an average. It can only be found by looking at the drive. This is the same reason we're honest that recovery isn't always possible; see the real problems with data recovery.

What we do instead

Rather than ask you to trust a number, we replace it with things you can actually verify and that put the risk on us, not you:

• A free evaluation. We diagnose your actual device and tell you, in plain language, what's recoverable and what isn't — a real assessment of your case, not an average of everyone else's.
• No data, no recovery fee. If we can't recover your data, you don't pay a recovery fee. That aligns our incentive with yours far more powerfully than any advertised rate: we only succeed when you get your files. (See our pricing for the full details.)
• An honest answer, including "no." When a drive is genuinely unrecoverable — overwritten data, a crypto-erased or key-lost encrypted drive — we tell you straight, instead of taking your money on a case we know won't succeed.
• A real person on your case. You can talk directly with the technician handling your recovery, ask what the failure is, and get a straight explanation — not a sales script built around a statistic.
• Verifiable reputation. Our Google reviews come from real customers and can't be edited by us. That's the kind of track record worth weighing.

How to read any lab's success-rate claim

If you're comparing recovery companies, a headline percentage is one of the least useful things to compare. Better questions to ask:

1. Do they offer a genuine free evaluation before quoting?
2. Is it truly no-data-no-fee, and what exactly does "no data" mean in their terms?
3. Will they tell you honestly when a case is unlikely or impossible?
4. Is the work done in-house, or shipped out to a third party? (Ours is done in our own Phoenix-area lab.)
5. What do independent reviews say?

A lab that answers those well is telling you far more than one that leads with "97%." Learn more about what separates professional recovery from the rest, or read how our process works.
