It may be possible to recover deleted pictures or files by using the Memory Card File Rescue application. Downloads are posted on your model support page.
If the Memory Card File Rescue application is unable to recover the image files, then the memory card or USB storage device 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 website or the DriveSavers Data Recovery website.
NOTE: Sony is not responsible for any data loss or any cost incurred from the recovery of data.
