Using a data recovery service is usually considered when the data recovery software route and other solutions fail to retrieve lost data. Using data recovery services is often considered to be a last resort option because these services can be expensive and can take several weeks between when you send the drive and when the recovered data is actually received.
However most services are quite good, to the extent that they can recover data from severely damaged hard drives. Some services, such as the Seagate owned i365, even have a ‘no data- no charge guarantee’ that ensures that customers don’t have to pay if their data can’t be recovered.
When to use professional data recovery services – You may need to use a data recovery service if your own effort to use off-the-shelf data recovery software has failed, or the hard drive is physically damaged. You may also need to use a professional service if the lost data is of high value and can’t be replaced or easily reacquired.
