It may be possible to recover deleted pictures or data from your SD card by using the Memory Card File Rescue software. This software is available as a free download online. Downloads are posted on your model support page.
If the Memory Card File Rescue is unable to recover your files, then the SD card may need to be sent to a professional data recovery service company, like Sony® Media Services or DriveSavers™ Data Recovery. For more information and pricing, visit the Sony Media Services Web site or the DriveSavers Data Recovery Web site.
NOTE: Sony is not responsible for any data loss or any cost incurred from the recovery of data.
