How to choose a data recovery service

  1. Ask whether physical repairs are done in a clean room or clean bench, and where.
  2. Ask for a written quote after diagnosis and whether there is a no-data, no-charge policy.
  3. Check how the drive and the recovered data are kept confidential and returned or destroyed.
  4. Ask for two or three references from clients of your size and industry, and call them.
  5. Get the scope, response times and price in writing before you sign, including how you leave and get your data back.

Questions to ask a data recovery service

  • Is the diagnosis free, and is there a fee if nothing is recovered?
  • Where is the recovery work actually done?
  • How long will it take, and what does a rush service cost?
  • How will you return the data, and what happens to the original drive?
  • How do you keep our data confidential?

An IT firm with no Google reviews scores zero on rating, review volume and recency; other factors we cannot measure are left out.

Do data recovery services outside Sunnyvale count in this ranking?

Yes, if they are within 50 mi of the Sunnyvale city center, our service radius for data recovery services. Each listing shows where the IT firm is based and how far away it is. Proximity is 5% of the IFR Score, so a nearby IT firm gets a small edge.

What should we do first when a drive fails?

Stop using it. Do not keep restarting the computer, run repair utilities or open the drive yourself: each attempt can make recovery harder. Note what happened and contact a recovery service.

How is data recovery priced?

Usually after a diagnosis, by the type of failure and the urgency. Many services charge nothing if no data is recovered; ask before you send the drive.
