Hi All, |

I was handed what seems to be a corrupt xD flash card to extract the last |
| 4 |
photo from it. When the WinXP system at work coughed and died on it |
| 5 |
(couldn't read it) I thought that my Linux would do better. Anyhow, I've |
| 6 |
inserted it into my Fuji camera and this is what dmesg shows: |
| 7 |
|

=================================================== |

In some cases useful info is found in syslog - try |
| 36 |
dmesg | tail or so |
| 37 |
==================================================== |
| 38 |
|
| 39 |
and dmesg then shows: |
| 40 |
==================================================== |
| 41 |
FAT: bogus number of reserved sectors |
| 42 |
VFS: Can't find a valid FAT filesystem on dev sda. |

This is what fdisk shows: |
| 48 |
==================================================== |
| 49 |
# fdisk /dev/sda |
| 50 |
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF |

Building a new DOS disklabel. Changes will remain in memory only, |
| 53 |
until you decide to write them. After that, of course, the previous |

content won't be recoverable. |

Is there a Linux (or even M$Windoze?) way of me recovering the last photo, |
| 71 |
that doesn't involve reconstructing raw data with a hexeditor? |
