Thanks. I'll check these apps out. |

So far the only life I've found is with e2fsck -b 32768 /dev/sda1. |
53 |
This starts finding some things that make sense name-wise but then |
54 |
starts complaining about other things. |

Again, it's just mythtv video files so those can probably just be |
57 |
rerecorded at some point. The backups were for my Windows machines |
58 |
which are working right now so as long as I make some new backups |
59 |
elsewhere I should be reasonably safe unless I find one day that |
60 |
something I need then isn't on my machine right now. |

Sad when your backup strategy goes against you... |

Again, thanks for the pointers. |
