The labor fee covers engineering time, imaging, clean bench work, and firmware rebuilds. The donor fee covers the physical part. We list them separately because the donor cost varies by model and availability. Some common 1 TB desktop drives have $50 donors. A discontinued helium enterprise model from 2018 might cost $500+. Bundling these into one number would force us to quote the worst case on every job.
We do not want to pad every quote with worst-case donor pricing when most jobs use a $50-$150 part. We also believe you should see real price ranges before you ship your drive, not a "call for quote" form that tells you nothing.
A large portion of the data recovery industry operates on opaque, call-for-quote pricing with zero published tiers. We think that model exists because it lets companies charge each customer whatever they think that customer will pay. We publish our pricing because we want you to know what you are getting into before you do business with us, not after your drive is already in someone else's hands in another state.
