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.
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.
