A great deal of advertised data recovery is collected in one place and performed in another. The counter that takes the drive, the company on the invoice and the engineer who opens it can be three separate parties, and you are usually told about the first one only. The price you were quoted then contains somebody else’s fee, a margin you were not shown, shipping risks, possible data theft and HIPAA violations or a broken chain of custody.

A mail-in operation is the same arrangement with the counter removed. A free evaluation, free shipping both ways and a no data, no charge guarantee all describe what happens before a price exists, not what the recovery costs. The figure is set once your only copy is already inside a building you have never seen, at which point declining it means asking for the drive back, wondering what was done to it and hoping that it returns in the same condition as when it left. When you pay nothing for a diagnostic, they aren’t required to give you any paperwork explaining what they did to it. A prepaid shipping label is not a convenience in that arrangement. It is the step that makes the rest of it possible.

The turnaround works the same way. When a standard wait is measured in weeks and faster tiers are sold at a premium, the premium buys a position in a queue, not a diagnosis. It is priced by somebody you will never speak to, before anyone has looked at your drive. On a flood-damaged drive, where corrosion continues every day it sits, weeks in a queue is the difference between a recovery and a loss.

That much is disclosed. Nothing past it is. So ask the question in a form that cannot be answered sideways: what town and what county is my drive opened in, and by whom? Ask for it in writing. A single laboratory answers with one company and one name. A partner facility, a lab network or somewhere nobody will name is the answer to a different question, and ask for the split while you are there. A company that performs its own recoveries has no reason to withhold it.
