File Format error

[fantaboy191]

Hi everyone,

I have an ARW file (RAW format from sony) which can not display the picture

Here are the result with ExifTool

ExifTool Version Number         : 9.66
File Name                       : DSC06228.ARW
Directory                       : C:/
File Size                       : 16 MB
File Modification Date/Time     : 2014:06:30 23:39:58+02:00
File Access Date/Time           : 2014:07:03 14:21:13+02:00
File Creation Date/Time         : 2014:07:03 14:21:13+02:00
File Permissions                : rw-rw-rw-
Error                           : File format error

Is there any suggestion to deal with file format error problem ?

I'm also upload the picture here : http://www.mediafire.com/download/rd8tdera1gyyfmu/DSC06228.ARW

Thank you in advance

This seems to be a common result of a corrupted memory card.  Most of the file is binary zeros, and there is no useful image that can be recovered:

The last command lists all lines in the hex dump which are not all zeros.  This looks like it could be a section of the file allocation table, instead of data from an ARW file.

The only way to recover this image is to go back to the memory card with some file recovery software.
