An IT firm with no Google reviews scores zero on rating, review volume and recency; other factors we cannot measure are left out. Only IT firms with a confirmed service and 3 or more reviews, or a claimed profile, are ranked.
Do data recovery services outside San Mateo count in this ranking?
Yes, if they are within 50 mi of the San Mateo 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.

No. The IFR Score never reads payment status, and this ranking has 0 paid placements. Up to 3 Featured IT firms may appear above the list, labelled Sponsored and showing their honest rank.

Data recovery services retrieve files from failed, damaged or deleted hard drives, SSDs, RAID arrays, servers and memory cards.

By IFR Score: Google rating and review volume, recent reviews, opening hours, how clearly the firm does data recovery, distance, a claimed profile, our badge and verified client reviews. Sponsored placements never change the order.
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.
