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.
